The invention discloses a novel cement anti-compression modifier. The modifier is prepared from the following raw materials, by weight, 2.5-3.8 parts of quartz-feldspar powder, 0.8-2.4 parts of polycarboxylic acid, 3.2-3.8 parts of a protease solution, 2.2-2.8 parts of n-octyl alcohol, 3.5-7 parts of dimethylpropyl ester, 1.7-2.6 parts of 6-dimethylphenol, 2.5-4.6 parts of aqueous amino acid-epoxy resin and 0.8-2.4 parts of nisin. Compared with cement products obtained by using present modifiers, a cement product obtained by using the novel cement anti-compression modifier has the advantages of high safety, good stability, simple construction, no special crack resistance layer, short construction cycle, low cost, energy saving, environmental protection, high tensile strength, high impact resistance, prevention of cracking of cement matrix due to long time pressure, enhancement of the durability of the cement matrix, and increase of the safety performance of buildings.
