Movement of concrete material
One of the main features of concrete is its movement that cannot capture by the naked eye. But concrete material shrinks and shifts at a minute level that causes the actual crack. And the main reason for this movement is thermal expansion and contraction. When concrete is exposed to the highest temperature, like fire, it starts to move and crack.
