Abstract
(EN)
Disclosed is a cement slurry formulation, characterized by comprising the following components in parts by weight: 25-40 parts of cement, 2-4 parts of a stabilizer, 3-5 parts of an epoxy resin, 10-15 parts of an iron ore powder, 8-12 parts of clay, 5-8 parts of glass fibers, 8-15 parts of gypsum, 4-10 parts of silica sand, 2 or 3 or 4 parts of a vermiculite powder, 10 or 15 or 20 parts of a dolomite powder and 80-120 parts of water. The addition of various assistants in the cement improves the stability, permeability resistance and crack resistance of the cement slurry, having low costs and being environmentally friendly, thereby saving on resources.
