In this type of cement it is necessary to decrease the ratio C 3 A less than 3.5, because this component reacts with Ca SO 4, which exists in soil or water. The result of this reaction is called Ettringite, which causes increasing in the concrete volume then causes cracks that lead to concrete failures.
