Flash set refers to the rigidity of the cement paste which can occur within 5-10 minutes of mixing with water and is referred to as irreversible rigidity. This is caused by the formation of aluminate hydrate due to high content of C₃A and / or a small amount of easily soluble calcium sulphate.

Cement produced with this behavior is unsuitable to use.

Flash set - Rapid rigidity with considerable heat generation, plasticity cannot be regained.

It differs from False set in that appreciable heat evolution takes place & that the plasticity of the paste can not be restored.
