Heat resistant concrete Everything About Concrete

At higher temperatures (above about 800 degrees F), high-heat-resistant concrete is generally needed. Light-weight aggregates have proven to be more heat resistant and so that is the first step--use lightweight. When temperatures get extremely high, (above 1000 degrees F), calcium aluminate cement produces a fire-resistant concrete.
