Why is asbestos added to concrete?
Faith Franz, content writer for the Mesothelioma Center, says, “Concrete precasters added asbestos to products to make them less permeable and less likely to crack. Asbestos was considered a good fiber reinforcement since it was inexpensive, readily available, and easily blended into the mix.” When construction workers encountered asbestos-reinforced concrete on the roof of a government building, the project was halted until the roofing and soft concrete layer were removed. The concrete was found to contain between 2% and 10% asbestos by weight, and the construction company was required to comply with OSHA methods for removal. Franz notes that a similar process should be taken with any project that involves asbestos concrete.

Visit the official OSHA Asbestos Training Requirements page here.
Why Add Asbestos to Concrete?
First, the presence of asbestos fibers embedded in a concrete mix can make the resulting structure or surface less likely to crack.

In addition, asbestos was chosen for its:
What Are the Dangers of Asbestos-Containing Concrete?
However, the situation changes when a repair, removal or modification job calls for the cutting of asbestos-impregnated concrete. Once cut open, the concrete will release mineral fibers into the air , exposing any unprotected workers or bystanders to significant health risks. As a rule, the greatest hazards occur in enclosed or indoor spaces. Some old structures may contain concrete with a relatively high asbestos content, leading to an even higher level of risk.

Once cut open, the concrete will release mineral fibers into the air, exposing any unprotected workers or bystanders to significant health risks. As a rule, the greatest hazards occur in enclosed or indoor spaces. Some old structures may contain concrete with a relatively high asbestos content, leading to an even higher level of risk.
Can asbestos be found in concrete?
When building materials such as wallboards and tiles break apart, a simple visual examination will reveal their asbestos content. The same does not hold true for asbestos embedded in a concrete mix. That’s the case, in large part, because the mixing process evenly distributes the mineral fibers and blends them in with the other concrete ingredients.
