Summary
DOC-GasStoDOCem Anti-channeling strength-enhancing cement slurry system is composed of DOC-G80L, DOC-H21L and DICO-H42L as basic additives, anti-channeling enhancer DOC-GS12L as core additive, retarding agent and other additives as auxiliary additives. DOC-GS12L is a high solid content aqueous suspension prepared by special technology. Its micro active particles can fill with the cement gaps tightly so as to achieve the role of anti-channeling and enhancing the cement strength.
