The effect of high temperatures on the mechanical
Oct 01 2011 · Concrete is well known for its capacity to endure high temperatures and fires owing to its low thermal conductivity and high specific heat. However it does not mean that fire or high temperatures do not affect concrete at all. Because concrete has relatively good insulating properties it tends to retain the heat of an exposing fire and release it slowly in an effect referred to as the Heat sink effect.

Why is concrete fire resistant HowStuffWorks
It s also incredibly resistant to fire which makes it a safe bet for homes. The fire-resistant properties of concrete are fairly easy to understand. The components of concretecement (limestone clay and gypsum) and aggregate materialsare chemically inert and therefore virtually non-combustible. Hence the crushed waste ceramic tiles were used in concrete as a replacement for natural coarse aggregates with 10 20 30 40 and 50 of substitution. After analyzing results the optimum
