Cement Expansive Agent

Brief Introduction:

compensate the volume shrinkage when slurry consolidates, and expand the cement sheath

BCP series expanding additives can compensate the volume shrinkage when slurry consolidates, and expand the cement sheath. They can improve the cement bonding quality and cementing quality by producing chemical prestress during the cement-setting process. BCP series expanding additives can be used alone or with other additives.They should be dry blended with cement. They include BCP-1S, BCP-200S and BCP-201S.
