Expansive Compound for Controlled Demolitions, Huaraz

Expansive cement is a compound designed to increase its volume while setting, unlike ordinary Portland cement, which typically shrinks. This property makes it an effective solution for situations where concrete shrinkage needs to be counteracted, cracks prevented, voids filled, or internal pressure applied capable of breaking concrete structures or rock formations. Depending on its degree of expansion and the speed at which it acts, it is classified into three types: I, II and III.
