▎ 摘　　要

NOVELTY - Cement modifier comprises 82.5-93 wt.% nano-seed crystal, 2-5 wt.% solubilizer, 3-7.5 wt.% precipitation accelerator and 2- 5 wt.% lattice modifier. USE - The cement modifier is used for cement (claimed). ADVANTAGE - The cement modifier combines the physical filling enhancement and chemical enhanced two ways, in the cement process, and has small doping amount, good enhance effect, can ensure proper initial coagulation, on the basis of final setting time, and obviously improves early and post-period strength of cement.
