The present invention discloses a novel cement modifier, which is prepared from the following raw materials by weight: 1.5-3.5 parts of asbestos, 2.5-3.8 parts of polypropylene, 2.5-5 parts of a furan resin, 0.5-1.2 parts of 2-ethyl formic acid, 1.5-2.2 parts of stearic acid, 1.8-3.3 parts of defatted miscellaneous meal powder, 1.2-1.8 parts of tributyl phenol polyoxyethylene ether, and 3.5-5.2 parts of N-methyl fatty amido taurate. Compared with the existing cement modifier in the prior art, the novel cement modifier of the present invention has the low cost, and well solves the technical problems of hardening, poor water resistance, low adhesion, no wear resistance, no freezing resistance of the cement. In addition, with verification of a lot of experiments, the results show that the performances of the ordinary cement are substantially improved after the modifier of the present invention is added to the ordinary cement.
