Roofing materials.
Concrete Floor Tiles.

Benefits of Asbestos Concrete

Asbestos improves the building’s energy efficiency and serves as an excellent thermal insulator.
It does not burn quickly and has a high level of fire resistance.
When combined with cement as an additive, it creates a composite material known as asbestos cement that is incredibly durable.
It is widely used since it is a highly affordable and efficient material.
In corrugated form, it is usually employed as a protective roofing material.
It is incredibly resilient and waterproof.
Asbestos is simple to maintain and clean but challenging to repair.
Boost tensile strength of concrete
Control plastic shrinkage and drying shrinkage to prevent cracking
Make the concrete less permeable to stop water seepage,
Unlike other fibres, which might make concrete harder to work with, it mixed smoothly into concrete mixtures.
Unlike other fibres that leave rust spots on the surface, it was corrosion-resistant.
It had little resistance. This made cement pipes particularly appealing.
Due to its greater strength-to-weight ratio, it has become a popular alternative to slate or clay for roofing.

Disadvantages of Asbestos Concrete

The fact that asbestos poses a substantial health risk is the main drawback of its use. When invisible microparticles from asbestos are discharged into the air, they can result in serious illnesses if ingested over an extended period of time.

Asbestos is being replaced with alternative materials as a result of this significant drawback.

Asbestos Nowadays

Although it is still legal to produce and utilize asbestos concrete in corrugated sheets, flat sheets, and shingles, American businesses long ago stopped domestic production as the expense of litigation increased. Anyone involved with the distribution chain is at risk from both its application and importation.

So it’s unlikely that you will ever see it in new construction. You’ll find that the bulk of asbestos cement now was created in the late 1980s or earlier. In addition to the issue of human disturbance of ancient concrete, we are beginning to see asbestos concrete’s surface erosion and disintegration as its 70-year lifespan approaches an end.

Old asbestos cement piping, which was frequently used in sewage systems, drainage pipes, and storm drainage systems, is especially worrying in this regard. Finally, siding and shingles are disintegrating as a result of typical weathering. Corrosion must be carefully inspected in order to avoid endangering the public’s health. Projects to demolish and replace outdated asbestos cement will continue to be widespread in the ensuing decades. There are threats to the workers’ health in every endeavour.

Safety when working with Asbestos Concrete

OSHA Construction Standard 29 CFR 1926.1101(g) must be followed when working with asbestos concrete in order to protect the crew and the public from asbestos fibres in the air.
