They are distinguished by long incubation periods, characteristic spongiform changes associated with neuronal loss, and a failure to induce inflammatory response.The causative agents of TSEs are believed to be prions. The term “prions” refers to abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins called prion proteins that are found most abundantly in the brain. The functions of these normal prion proteins are still not completely understood. The abnormal folding of the prion proteins leads to brain damage and the characteristic signs and symptoms of the disease. Prion diseases are usually rapidly progressive and always fatal.__________________________________________________To destroy a prion it must be denatured to the point that it can no longer cause normal proteins to misfold. Sustained heat for several hours at extremely high temperatures (900°F and above) will reliably destroy a prion.__________________________________CEMEX UK | View CEMEX Aggregates Extraction Processes . … the majority of coarse aggregate used in concrete with crushed stone making up most of the … Aggregation Process of the Prion Ure2p: Insights on Vesicle Permeabilization and.SEARCH –What would be the benefit to multinational corporations, such . . .Jul 14, 2020 — … solve: What would be the benefit to multinational corporations, such as CEMEX , … Choosing Carnegie, Ford, or Rockefeller, or a more recent.

TOXIC Cloud of cement dust from Cemex Plant Cloud of cement dust from Cemex plant in Victorville triggers fire department response Published 11 months ago on April 24, 2020By Victor Valley News Group VICTORVILLE, Calif. (VVNG.com) — A cloud of cement dust from a Cemex plant in Victorville triggered a response from the fire department Friday evening.On April 24th, 2020, at 5:05 p.m., the Victorville Fire Department responded to reports of a commercial structure fire at the plant, located at 16888 E St. in Victorville, after people reported the cloud of building material particles as a fire.“It was not a fire,” stated Victorville City Spokeswoman Sue Jones. “Cemex was filling a silo. It was cement dust that resembled a smoke cloud.”Cement is the main ingredient in concrete and is a very fine powder that can be dangerous.“Every two days we got to wash our car with muriatic acid, [and Cemex] won’t do a [expletive] thing about it,” he stated. “You know, they’re a global company.”“That usually doesn’t happen until Sunday morning when nobody’s up,” he stated as he pointed to the dust cloud.According to Osha.gov, exposure to cement dust can irritate eyes, nose, throat, and the upper respiratory system.Skin contact may result in moderate irritation to thickening/cracking of skin to severe skin damage from chemical burns. Exposure to silica, which is often in cement, can lead to lung injuries including silicosis and lung cancer, the government website stated.Osha suggests that anybody who is experiencing symptoms should rinse their eyes with water if they come into contact with cement dust and consult a physician, use soap and water to wash off the dust to avoid skin damage, and wear a P-, N- or R-95 respirator to minimize inhalation of cement dust.There was no report of injuries at the Cemex plant and at 5:30 p.m., the excess dust escaping from the silo had stopped.________________________________________________________________________ EXAMPLE 1A light colloidal concrete is prepared by using:a commercially available cement (cement CPA 400), a silico-calcareous sand graded no higher than 0.8 mm (the cement/sand mass ratio being equal to 1), whole blood powder of animal origin, a colloid, and mixing water in variable proportions.The various constituents are mixed by means of a mixer working between 100 and 600 r.p.m. US patent 1,020,325 from 1912 which described mixing blood into concrete. ______________________________________________________________ https://www.nationalgeographic.com/travel/article/things-to-see-bone-church-sedlec-ossuaryBones of 30,000 Plague Victims Decorate This Church Search – bone church czeck republic From Skull Chapel in Poland to Medieval Ossuary in Spain, here are eight of the coolest churches made of bones from around the world.Sedlec Ossuary, Czech Republic. … San Bernardino alle Ossa, Milan. … Skull Chapel, Czermna, Poland. … Capela dos Ossos, Portugal. … Monastery of San Francisco, Peru. … Medieval Ossuary, Spain. ______________________CEMEX Organizes its 3rd “Blood” Donation Drive26 Jul 2017 CEMEX is a “global building materials company” that provides high quality products and reliable service to customers and communities in more than 50 countries.

(“CEMEX”) (NYSE: CX) announced today a new Climate Action strategy, which outlines the company´s vision to advance towards a carbon-neutral economy and to address society’s increasing demands more efficiently. In CEMEX, we believe that climate change is one of the biggest challenges of our time and support the urgency of collective action.As a result of our efforts to date, we have reduced our net specific CO2 emissions by more than 22% compared to our 1990 baseline. But we acknowledge that this is not enough. This is why we have defined a more ambitious target of a 35% reduction of net specific CO2 emissions by 2030. This new goal is aligned with the Science-Based Targets methodology, a requirement climate science says is necessary to meet the goals of the Paris Agreement.To complement this strategy with a longer-term vision, CEMEX is also establishing a new ambition to deliver net-zero CO2 concrete by 2050. In our business, we believe concrete—our end product—has a key role to play in the transition to a carbon-neutral economy, and is an essential component in the development of climate-smart urban projects, sustainable buildings, and resilient infrastructure.“Climate change has been a priority for CEMEX for many years. Our efforts have brought significant progress to date, but we must do more. This is why we have defined a more ambitious strategy to reduce CO2 emissions by 2030 and to deliver net-zero CO2 concrete by 2050,” said Fernando A. Gonzalez, CEO of CEMEX.This press release contains forward-looking statements within the meaning of the U.S. federal securities laws.

He cited a variety of earlier patents, such as US patent 1,020,325 from 1912 which described mixing blood into concrete. And, in fact, the technique of using blood to make concrete was even practiced by the ancient Romans. What made Laleman’s technique unique (and therefore patentable) was apparently that he used it specifically to lighten the concrete, rather than to color it or to make it more porous. That seems like a rather fine distinction to me, but it was enough to earn him a patent.

Here’s how the cement business worked in Mexico’s second-largest city, Gua-dalajara, only a couple of years ago: A builder telephoned in an order a day or so ahead, two days in advance […] Cemex has its First World operations – through astute acquisitions, it’s now Spain’s top cement supplier and has a US subsidiary based in New Braunfels, Texas. But it specializes in places that lack highly developed road systems, solid telephone networks, etc.Cemex’s own satellite system, hooks up every plant and office, providing streams of real-time data on everything from daily sales and output to truck oil change schedules. Technical flying squads get newly acquired subsidiaries online in only a few months. There’s a private satellite TV network for in house training and videoconferencing. A local call from virtually anywhere on the planet hooks traveling executives directly into the companywide international phone system.Cemex is a company on a high tech roll that has carried it in scarcely a decade from a sleepy perch in northern Mexico to its place as the world’s third-largest cement company. Its 20,000-plus people, 486 plants, thousands of vehicles, and fleet of freight ships move more than 50 million tons of the stuff annually in 60 countries – including places that make Guadalajara look like Geneva. Cemex executives will dutifully tell you that the idea of going high tech came from chair and CEO Lorenzo Zambrano, a 53-year-old Stanford MBA whose grandfather consolidated Cemex as a modern company in the 1920s.

The recommended process for preparing a lightened material consists in associating a construction element chosen from the cements, mortars and concretes, with at least one air entraining colloid chosen from whole blood, globules, red blood corpuscles and haemoglobin. The invention also relates to the lightened material obtained according to this process. The term “blood” is here understood to mean whole animal blood or an extract of animal blood containing haemoglobin. The following may be mentioned in particular among the extracts of animal blood which are suitable:the globules, i.e. all the elements constituted by the red blood corpuscles, the white blood corpuscles and the thrombocytes, this resulting from the elimination of the plasma;the red blood corpuscles, andthe haemoglobin which is the colouring matter of the red corpuscles.It has been ascertained that, in the blood, it is mainly the red blood corpuscles and the haemoglobin which have the sought after air entraining properties. Therefore, for economical reasons, whole blood or an extract of blood which is more or less rich in red blood corpuscles or haemoglobin may preferably be used, depending on the costs of treating blood.To facilitate the conservation and storage, the animal blood or extract of animal blood are advantageously brough into powder form either by drying, freeze drying or by applying any other method known per se.The preferred use of blood according to the invention for obtaining a lightened material consists in associating the blood, the globules, red blood corpuscles or haemoglobin with at least one other colloid. ____________________________________________________________ https://www.nanowerk.com/news2/gadget/newsid=54160.php ‘Buildings’ in human bone may hold key to stronger 3D-printed lightweight structures(Nanowerk News) What do bones and 3D-printed buildings have in common? They both have columns and beams on the inside that determine how long they last.Now, the discovery of how a “beam” in human bone material handles a lifetime’s worth of wear and tear could translate to the development of 3D-printed lightweight materials that last long enough for more practical use in buildings, aircraft and other structures.A team of researchers at Cornell University, Purdue University and Case Western Reserve University found that when they mimicked this beam and made it about 30% thicker, an artificial material could last up to 100 times longer. |

| Would YOU Live in a City Made of BONE ? ? The cities of today are built with concrete and steel – but some Cambridge researchers think that the cities of the future need to go back to nature if they are to support an ever-expanding population, while keeping carbon emissions under control. “The material properties of bone and wood are very similar,” says Oyen. “Just because we can make all of our buildings out of concrete and steel doesn’t mean we should. But it will require big change.” https://www.cam.ac.uk/research/features/would-you-live-in-a-city-made-of-bone Concrete and steel are responsible for as much as a tenth of worldwide carbon emissions. Before they ever reach a construction site, both steel and concrete must be processed at very high temperatures – which takes a lot of energy. And yet, our cities are completely dependent on these two “unsustainable materials”. Just think NATURAL construction materials will reduce your carbon footprint. People assume that air travel is a huge contributor to carbon emissions,” says bioengineer Dr Michelle Oyen of Cambridge’s Department of Engineering. “But the truth is, while the emissions caused by air travel are significant, far more are caused by the production of concrete and steel, which of course is what most cities are built from.” So what does that mean for cities of the future, as more and more of us live in urban areas? How can we continue to build while reducing carbon emissions?Whereas some researchers are investigating ways of producing steel and concrete in more energy-efficient ways, or finding ways of using less, Oyen would rather turn the tables completely, and create new building materials that are strong, sustainable and take their inspiration from nature.“What we’re trying to do is to rethink the way that we make things,” says Oyen. “Engineers tend to throw energy at problems, whereas nature throws information at problems – they fundamentally do things differently.”Oyen works in the field of biomimetics – literally ‘copying life’. In her lab, with funding support from the US Army Corps of Engineers, she constructs small samples of artificial bone and eggshell, which could be used as medical implants, or even be scaled up and used as low-carbon building materials. Like the real things, artificial bone and eggshell are composites of proteins and minerals. In bone, the proportions of protein and mineral are roughly equal – the mineral gives bone stiffness and hardness, while the protein gives it toughness or resistance to fracture. While bones can break, it is relatively rare, and they have the benefit of being self-healing – another feature that engineers are trying to bring to biomimetic materials.In eggshell, the ratios are different: about 95% mineral to 5% protein, but even this small amount of protein makes eggshell remarkably tough considering how thin it is.When making the artificial bone and eggshell, the mineral components are ‘templated’ directly onto collagen, which is the most abundant protein in the animal world. “One of the interesting things is that the minerals that make up bone deposit along the collagen, and eggshell deposits outwards from the collagen, perpendicular to it,” says Oyen. “So it might even be the case that these two composites could be combined to make a lattice-type structure, which would be even stronger – there’s some interesting science there that we’d like to look into.”In her lab, Oyen and her team have been making samples of artificial eggshell and bone via a process that could be easily scaled up – and since the process takes place at room temperature, the samples take very little energy to produce. But it may be some time before we’re living in bone and eggshell houses.For one, the collagen that Oyen needs to make these materials comes from natural (meaning animal) sources. One of the things she’s currently investigating is whether a non-animal-derived or even synthetic protein or polymer could be used instead of natural collagen.“Another issue is the construction industry is a very conservative one,” Oyen says. “All of our existing building standards have been designed with concrete and steel in mind. Constructing buildings out of entirely new materials would mean completely rethinking the whole industry. But if you want to do something really transformative to bring down carbon emissions, then I think that’s what we have to do. If we’re going to make a real change, a major rethink is what has to happen.”Dr Michael Ramage from the Department of Architecture is another Cambridge researcher who believes we need to expand our use of natural materials in buildings. Ramage has several ongoing research projects that are looking into the use of wood – one of the oldest building materials we have – for tall buildings. _______________________________________________________ As economic and political power shifts worldwide, ‘new champions’ are emerging regionally that force us to rethink solution s to global and industry challenges.

Therefore, for economical reasons, whole blood or an extract of blood which is more or less rich in red blood corpuscles or haemoglobin may preferably be used, depending on the costs of treating blood.To facilitate the conservation and storage, the animal blood or extract of animal blood are advantageously brough into powder form either by drying, freeze drying or by applying any other method known per se.The preferred use of blood according to the invention for obtaining a lightened material consists in associating the blood, the globules, red blood corpuscles or haemoglobin with at least one other colloid.The process of preparation, according to the invention, of a lightened material is characterised in that at least one air entraining colloid chosen from whole blood, globules, red blood corpuscles and haemoglobin is associated with the construction element chosen from cements, mortars and concretes.According to a preferred embodiment, the process for preparing a mortar or lightened concrete consists in associating, with stirring and in the presence of mixing water:(a) a mixture of cement and sand, and(b) at least one air-entraining colloid in powder form chosen from whole blood, globules, red blood corpuscles and haemoglobin,the quantity of air entraining haemoglobin (b) being advantageously comprised between 0.1 and 1% by weight with respect to the weight of the cement contained in mixture (a).Stirring is one of the essential elements according to the invention. The association, comprising water, the mixture (a), the air entraining colloid (b) and, if necessary, the colloid (c) which will be mentioned hereinbelow, is obtained by means of a mixer working between 100 and 600 r.p.m. Below 100 r.p.m., an insufficient quantity of air is incorporated. The mixer will preferably work at 200 r.p.m., the duration of mixing generally being from 3 to 10 mins.In the mixture (a), the cement/sand mass ratio may in particular be between 0.3 and 1.5. Of course, light aggregates graded between 0.1 and 25 mm may be added to the cement/sand mixture. These light aggregates may be expanded schist, polystryrene balls, expanded glass, vermiculite, perlite or mica.To prepare a light colloidal concrete comprising a very stable network of spherical micro air-bubbles, whose diameter is between 1μ and 1 mm, having a good mechanical resistance and a low density (for example a density of 0.8 to 1.3 kg/dm3after 28 days), the recommended process consists in associating the mixture (a) of cement and sand with at least one air entraining colloid (b) and at least one other colloid (c). The quantity of colloid (c) is then advantageously between 0.025 and 1% by weight with respect to the weight of the cement contained in the mixture (a).The colloids (c) which may be used according to the invention, may be constituted, in particular, by cellulosic derivatives, such as degraded starch, esters and ethers of cellulose, alginic derivatives, derivatives of silane and polyalkyleneoxides (e.g. those which contain from 7 to 22 units alkyleneoxide per molecule) and mixtures thereof. The preferred colloids (c) according to the invention are hydroxyethylcellulose, carboxymethylcellulose, hydroxypropylmethylcellulose and polyethyleneoxides, the most advantageous being the polyethyleneoxides as they act not only as colloids but also as foaming agents and thus make it possible to use, if necessary, a quantity of product (b) close to the lower limit given hereinabove. 0.1 to 5% by weight of polyethyleneoxide with respect to the weight of the cement of mixture (a) may advantageously be used.The association of (a) and (b) and possibly (c) is effected at the moment of mixing with mixing water. According to a similar technique, ready-mixed dry light mortars, may be prepared. The water/cement mass ratio is between 0.35 and 0.45.Other advantages and features of the invention will be more readily understood on reading the following examples of light colloidal concrete. In particular in Example 1, the colloids (c) used were hydroxyethylcellulose (marketed under the name of “Natrosol” by Hercules-France), carboxymethylcellulose (marketed under the name of “Blanose” by Novacel) and hydroxypropylmethylcellulose (marketed under the name of “Methocel” by Dow Chemical; two varieties of hydroxypropylmethylcellulose designated by Methocel No. 1 and Methocel No. 2 were used). In these Examples, the percentages of air entraining colloid and of colloid are expressed by weight with respect to the weight of the cement contained in mixture (a).EXAMPLE 1A light colloidal concrete is prepared by using:a commercially available cement (cement CPA 400),a silico-calcareous sand graded no higher than 0.8 mm (the cement/sand mass ratio being equal to 1),whole blood powder of animal origin, a colloid, andmixing water in variable proportions.The various constituents are mixed by means of a mixer working between 100 and 600 r.p.m.The results obtained after 2, 7 and 28 days shown in Table I hereinbelow, in which:W/C represents the water/cement mass ratio,d represents the density of the materialTB represents the tensile strength in bending (in kg/cm2),andC represents the simple compressive strength (in kg/cm2) TB and C being determined after conservation in air in the presence of humidity (20° C.; 50% HR).By proceeding as indicated in the Example given hereinabove, it is possible 1) to incorporate a filler, particularly a calcareous filler, or 2) to replace the sand or a part thereof by a suitable quantity of light aggregates such as for example polystyrene, expanded slag, vermiculite, perlite and expanded schist.Generally, by playing on the percentage of blood powder or of powder of blood extract containing haemoglobin, on the percentages of colloid and on the modi operandi, in the proportions given hereinabove, the density of the hardened colloidal concrete may be varied from 0.5 to 1.8 kg/dm3 with, correlatively, a simple compressive strength of 5 to 350 kg/cm2.EXAMPLE 2A light colloidal concrete is prepared by mixing, for 4 mins. at 200 r.p.m., a composition comprising water, a mixture of 100 kg of sand (graded no higher than 0.2 mm) and of 100 kg cement (CMP 400), 2 kg of blood extract, 0.6 kg of a cellulosic colloid (carboxymethylcellulose) and 0.3 kg of polyethyleneoxide with a view to comparing three products obtained from blood, namely: whole blood powder, powder of red blood corpuscles and powder of ox plasma, the latter not containing haemoglobin, the water/cement mass ratio (W/X) being 0.42.The density (d) of the material thus obtained as well as the TB and C strengths are determined after 7 and 28 days, as defined in Example 1. The results given in Table II show that the powders containing haemoglobin (whole blood powder and powder of red blood corpuscles) lead to lower densities.EXAMPLE 3A light colloidal mortar is prepared by mixing, for 4 mins. by means of a mixer working at 200 r.p.m., water, cement (CPA 400), sand graded no higher than 0.1 mm and a mixture of colloids (hydroxyethylcellulose and whole blood powder in a mass ratio 0.3:1), the water/cement (W/C) mass ratio being 0.42.For the material obtained at each test, the apparent density is measured (in kg/m3) as well as the TB and C strengths, after 7 and 28 days (in kg/cm2), the heat conductivity when dry (in W/m2 ° C.) and shrinkage after 28 days. The results are shown in Table III hereinbelow.When fresh, the light colloidal mortar obtained according to each test of Example 3 is fat adhering well to the support. It can easily be pumped and is projectable with the mortar-gun. The vibrations, pumping and projection do not destroy the micro-air bubbles.The setting time of the light colloidal mortar is slightly extended, this giving the material a longer application time, but is is possible to accelerate it by means of an accelerator known per se.The heat shrinkage of this material is of the same order of magnitude as that of a conventional concrete (10 μ/m/° C.). Moreover, as shown by the result of Table III hereinbelow, the compressive strengths obtained after 28 days of conservation in damp (20° C.; 50% H.R.) are:50 kg/cm2 for the economical mixture (low colloid content) of light colloidal mortar of density 1100 kg/m3, and212 kg/cm2 for the light colloidal mortar of density 1500 kg/m3.The ratio TB/C varies between 0.60 and 0.30 according to the density, instead of 0.15 to 0.20 for conventional concretes. The substantial increase of this ratio translates a considerable reduction in the fragility of the material and a great faculty of accommodation under the pulling forces.The hydraulic shrinkage after setting of the light colloidal mortar is greater than that of a concrete in view of the high content of fine elements, but, what is important in a lining, is the fissurability. The modulus of elasticity of the light colloidal mortar according to the invention is of the order of 60 000 kg/cm2, or about 1/5 of that of a conventional concrete, in other words, with equal stresses, the mortar according to the invention deforms five times more than a conventional concrete. It is this deformability which protects this light material against cracks. The high resistance to cracking and the plasticity are due to the presence of numerous air bubbles which stop the possible micro-cracks, similarly to a hole which is made at the end of a crack in a window to stop propagation thereof.The light colloidal mortar is only slightly capillary and is perfectly resistant to the freezing-thaw cycles. Finally, the dimensional variations (swelling/shrinking) during the drying/humidification cycles are substantially the same as those of a conventional concrete.In view of these properties, the light colloidal mortar according to the invention is perfectly usable in the domains of single-layer linings and outer insulating linings.
