摘要
采用晶种作为防冻剂中的早强组分，试验时对比了晶种防冻剂与普通防冻剂的性能，发现晶种防冻剂不但大量降低混凝土中的盐掺量，而且各项性能均能达到和超过普通防冻剂的水平。试验发现负温体系中晶种的作用仍然是促进水泥的水化速度。
Crystal nucli is used as an early strength component of anti freezing admixture It is found that,compared with the admixture without crystal nucli,the salt content of anti freezing admixture is not only decreased greatly,but its all properties is also incresed It is concluded that crystalnucli accelerates the hydration of cement at negative temperatures
