The invention discloses a cement anti-compression modifier, which is composed of the following raw materials in parts by weight: 2.5 to 3.8 parts of quartz-feldspar powder, 0.8 to 2.4 parts of polycarboxylic acid, 3.2 to 3.8 parts of trisodium phosphate, 2.2 to 2.8 parts of n-octanol, 3.5 to 7 parts of dimethyl propionate, 1.7 to 2.6 parts of 6-xylenol, 2.5 to 4.6 parts of aqueous amino-epoxy resin, and 0.8 to 2.4 parts of zinc dialkyl dithiophosphate. Compared with cement modified by conventional modifiers, the cement modified by the provided cement modifier has the advantages of higher safety, better stability, and more convenience in construction, a special anti-cracking layer is not required, the construction period is short, the cost is low, and moreover, the modified cement is energy-saving and environment-friendly, and has a high tensile strength, a good impact-resistant performance, and a good anti-cracking performance, so the phenomenon that the cement base cracks due to the long-term compression is avoided, furthermore, the durability of cement base is enhanced, and thus the safety of buildings is strengthened.
