Portland Cement Type 5
This type of cement has good strength against sulfate attacks; it is suitable for places where soil and underground water is high in sulfate . So the designations for Type V cement focus on keeping the C3A content low. Also alkali content of type 5 cement is low (in terms of sodium oxide equivalent is approximately %0.8); it is preferred in environments with the risk of damaging reaction of silica and alkali.
