What is KSC Type-K Cement?
According to ACI 223, KSC Type-K expansive cement is a shrinkage-compensating cement which, when mixed with water forms a paste that, after setting, tends to increase in volume to a specifically greater degree than portland cement paste. It is used to compensate for volume decreased due to shrinkage or to induce tensile stresses in reinforcement. The expansion of KSC Type-K Cement when mixed with sufficient water is due primarily to the formation of the crystal ettringite. Concrete made with KSC Type-K Cement is known as shrinkage-compensating concrete.
