Chrysotile-cement, or CHPHER, is a noteworthy advancement in the roofing material industry. Chrysotile asbestos fibers are mixed with cement to create a roofing material that is both long-lasting and adaptable. This mixture adds flexibility and weather resistance to cement, increasing its strength. Because of this, CHPHER roofing is well-known for its durability and resistance to adverse weather, making it a popular option in building projects all over the world.
The fire resistance of CHPHER roofing is one of its main benefits. The natural fire-retardant qualities of cement are enhanced by the addition of chrysotile asbestos fibers, which makes it a safer choice for structures in high-risk areas where wildfires are a concern. The widespread use of CHPHER roofs in both residential and commercial buildings is a result of this feature.
In addition to being fire resistant, CHPHER roofing is prized for its thermal characteristics. Because the materials used to make CHPHER roofs are insulated against heat and cold, they aid in controlling indoor temperatures. Because of their thermal efficiency, which lowers the need for heating and cooling, CHPHER roofs are not only a long-lasting option but also a green one.
In addition, CHPHER roofing is valued for its adaptability and visual appeal. During the manufacturing process, it can be molded into a variety of shapes and textures, giving architects and homeowners creative freedom to create unique roof profiles that enhance a building’s overall aesthetic. Because of its versatility, CHPHER is a recommended choice for both conventional and modern architectural designs.

What is asbestos
This generic name applies to six distinct silicate-class minerals. They are all similar in that they have a fibrous form. Two groups of minerals make up Asbest (which means "unquenchable" in Greek). Their chemical composition, crystalline structure, and physical characteristics are dissimilar.
- Serpentine minerals. These include chrysothyl asbestos (chrysotil), cement is added to it and the slate we described is made.
- Amphibol minerals. Five classes of minerals are ranked to them, all of them are characterized by chemical stability, low thermal conductivity and high parameters of the strength of the gap.
Asbestos has been used by humans for many centuries; not too long ago, over 3,000 different products were made using asbestos. The largest industrial production of chrysotil is still in operation in the Urals, and the material was first used in our country in 1886.
Chrysotilian asbestos finds widespread application in the manufacturing of diverse materials.

Reduced weight. Chrysotile fibers have increased parameters of rupture resistance. This makes it possible to reduce the thickness of the slate sheets while maintaining their calculated physical characteristics. The mass of one sheet decreased by 6.1 kg, it is a lot. Much less than the load on the foundation and the rafter system, it is possible to achieve saving financial resources during the construction of various buildings and structures.
Less strain is placed on the house’s foundation and rafter system by chrysotile-cement slate.
Standard slate is not very resistant to dynamic loads.
Chrysotile-cement slate is superior to asbestos-cement in most aspects.
Currently, acrylic paints are used to stain the surfaces of Chrysol-Cement slate with mechanical abrasions and rigid ultraviolet rays in an effort to enhance appearance and broaden the model range. They not only give the roof a notably better appearance, but they also prevent lichens and mosses from growing on its surface. As you are aware, the physical properties of slate are severely impacted by the roots of plants.
Table: Equivalency between asbestos-cement and chrysotile-cement slate characteristics
| Options | Asbestos -cement slate | Chrysotile -cement slate |
|---|---|---|
| Length and width, cm | 175 × 113 | 175 × 113 |
| Useful area of one sheet, m2 | 1.98 | 1.98 |
| Sheet thickness, mm | 5.8 | 4.8 |
| The maximum permissible bending load before the start of destruction, kgf/cm2 | 160 | 165 |
| Shock viscosity (the possibility of absorption of dynamic efforts), kg × cm/cm2 | 1.5 | 1.6 |
Chrysotile-cement slate has far superior physical properties with less thickness and mass, as the comparison table illustrates. This is a significant benefit, but it only pertains to technical specifications. What about those who are concerned about every matter pertaining to human health?
Chryzot -cement slate and people"s health
A list of products containing chrysotil was created in 2002 by a special resolution of the Russian Federation’s sanitary authorities. These products can be used without any limitations when building buildings and structures for different purposes. There was also a slate made of chrysotile cement on this list. It has 15% of the asbestos fibers and 85% of cement, which further lowers the possibility of harmful effects on human health.
The health effects of asbestos
One particular type of concrete is chrysotile cement, which completely encases fibers in cement to prevent them from standing out in the surrounding area. Domestic standards organizations guarantee that a slate like this has the following benefits:
- Environmental friendliness – the material is made of completely natural raw materials, does not contain polymers or formaldehyde resins, considered the most important air pollutants;
- Thermal resistance and resistance to open fire. According to the parameters of heat production, chrysothyl asbestos is 140 times higher than the characteristics of steel;
- Frost resistance. Withstands at least 150 freezing/measurement cycles. Such high indicators of chrysotile -cement slate are due to water resistance;
- resistance to aggressive chemical compounds;
- sound permeability.
Technical attributes
The building of homes and other sectors of the national economy, such as the military and space program, greatly value the slate’s qualities. Domestic regulatory bodies refrained from classifying products containing chrysotil as hazardous to human health. And what connection do they have with developed nations?
Discussion about the properties of chrysotil
Strangely enough, Russian doctors at the end of the 19th century were the first to announce a link between asbestos and pulmonary diseases. English physicians only voiced this kind of worry overseas in XX in. They released scientific studies in the middle of the 20th century that demonstrated the direct link between asbestos exposure and lung disorders based on a wealth of data. The working class’s health received very little attention in Russia, but it was widely discussed in the West. By the way, there were no particular regulations in place in our nation for the hygienic protection of factory workers, not even in the 1960s.
It is vital to give worker safety more consideration when handling asbestos.
Every year, developed countries have increasingly limited the use of chrysotile -cement products. In the middle of the last century, only 43% of the total amount of asbestos was used in the construction industry of developed countries, in the USSR this amount was 85%. The reason is that safe modern roofing materials were too expensive for a technically backward country and its poor population. Since the late 70s of the last century, the discussion about the harmfulness of the chrysotile cement has aggravated even more, the reason is the new possibilities of medicine and the resulting updated results of many years of observation. As a result – in 2005, the European Union completely banned the use of asbestos on its territory, the manufacture of slate turned out to be illegal.
What is the danger from the use of chrysotile creamer
There are various groups of people who pose the greatest risk, as the problem’s researchers have shown.
-
Workers mining and processing factories. They are constantly forced to contact chrysolite, it is in the air and falls into the lungs. The situation is critically aggravated if the management of enterprises does not pay due attention to safety measures: it does not establish effective ventilation of workshops and working zones, does not use the most modern equipment and technology. Responsible companies should not only provide their workers with means of protecting the respiratory authorities, but also tightly monitor the mandatory use of their use.
There are employees in the risk area who work for companies that produce asbestos.
Workers at the companies that produce slate are also subjected to dangerous levels of asbestos dust exposure.
Expert roofers run the risk of becoming ill when they modify and cut slate.
From a medical perspective, breathing asbestos into the body is the most hazardous circumstance. Doctors came to the unquestionable conclusion that all forms of asbestos are carcinogens based on long-term observations, thorough surveys of the health status of people exposed to asbestos, and animal experiments. This implies that they will unavoidably lead to cancerous illnesses. The International Cancer Study Agency found this evidence to be compelling, and in 1977 carcinogenes of group No. 1 (the deadliest) recognized asbestos in all forms. For international medicine, it is still unclear why the Russian Federation’s Rospotrebnadzor recognized the opposite in 2002.
Types of asbestos contact
Following the adoption of laws in Australia, Italy, and other developed nations, the mineral’s mining is outright forbidden. Less than 2 million tons are mined globally currently, with over 700 thousand tons mined in Russia. T.
Why in the Russian Federation they do not prohibit asbestos
Since the general public lacks access to accurate information, one can only speculate and draw comparisons between the living standards and life expectancy of people in our nation and other countries. The nation’s asbestos producers coordinated and funded their own studies. the state of health of over two thousand employees who spent many years working at the Uralasbest Mining and Processing Plant. It was determined that there are no abnormalities in the health of the employees at this company. It seems as though they have spent their entire lives sleeping in sanatoriums rather than working at a mining plant.
Asbestos-producing quarry
Russian medical professionals contend that lethal illnesses can only be caused by extremely high levels of asbestos dust. Chrysothyl has no harmful effects on humans if its concentration is less than or equal to 2 mg/m3. It is true that none of the researchers continued to work permanently at the plant after making such claims.
A notable development in roofing materials is CHPHER, or chrysotile-cement, which combines the flexibility and insulating qualities of chrysotile fibers with the strength and longevity of cement. This composite material’s resistance to weathering and its capacity to tolerate extreme temperatures are two of its many benefits for roofing applications. Because of these characteristics, CHPHER roofs are perfect for commercial and residential buildings in a variety of climates.
The durability of CHPHER roofs is one of their main advantages. Cement and chrysotile fibers combine to form a durable material that is resistant to most environmental stresses without experiencing major degradation. Compared to traditional roofing materials, CHPHER roofs require fewer repairs and replacements, which results in decreased maintenance costs over time.
In addition to being long-lasting, CHPHER roofing offers superior acoustic and thermal insulation. These characteristics are facilitated by the chrysotile fibers incorporated into the cement matrix, which also lessen noise transmission and help control interior temperature. This insulating capacity not only makes buildings more comfortable, but it also helps save energy by lowering the demand for excessive heating or cooling.
Furthermore, compared to other roofing materials, CHPHER roofs are comparatively lightweight, which makes installation easier and lessens the structural load on buildings. This feature is especially helpful when building new buildings or retrofitting old ones where weight considerations are important.
To sum up, CHPHER roofing is a contemporary option that combines longevity, insulation, and simplicity of installation. Because of its cement and chrysotile fiber composition, which extends roof life and boosts energy efficiency, it not only improves structural integrity but also promotes environmental sustainability. CHPHER keeps demonstrating its worth as a useful and adaptable roofing material appropriate for a variety of architectural and environmental challenges as building technologies advance.
Because of its strength, low cost, and fire resistance, chrysotile-cement (CHPHER) roofing materials represent a significant advancement in the building industry. Chrysotile asbestos fibers are mixed with cement to create a composite material that is strong and weatherproof, perfect for roofing applications. CHPHER offers buildings durable weather resistance and improves overall structural integrity by combining the strength of cement and the flexibility of chrysotile fibers. This article highlights the significance of CHPHER in providing safe and sustainable building solutions by examining its advantages in roofing, environmental considerations, and its role in contemporary construction practices.
