 · Concrete is a brittle material, which means, it fails suddenly when the stress due to external load reaches it's ultimate strength. For example, a concrete cylinder with a compressive strength of 20 mPa (M20 according to Indian Standard), fails when the stress due to external load reaches slightly higher than the value.
