摘要：采用沉淀法制备形貌分别为类纤维状、类球形堆叠状及团聚锡箔状的水化硅酸钙（C-S-H），并探究了不同形貌C-S-H对水泥水化产物形貌及水泥性能的影响。结果表明：不同形貌的C-S-H对水泥浆体的微观形貌有调控作用；C-S-H能有效缩短凝结时间，加快水泥水化速度，并提高水泥浆体的早期强度，其中纤维状的C-S-H分散性最好，对水泥性能的提高效果最为显著。

Abstract：Calcium silicate hydrate（C-S-H） with different morphology was synthesized by precipitation method. There are three different types of morphology：the class fibrous，the spherical stacked and reunion foil. And the effect of different morphology of C-S-H on morphology of cement hydrated productsand cement performance was studied. The results show that C-S-H with different morphology can regulate the morphology of cement hydration products.Adding C-S-H can effectively shorten the setting time，speed up the cement hydration and improve the early strength of cement paste. The morphology of fibrous C-S-H with the best dispersion have the most significant effect on the cement performance.
Key words：calcium silicate（C-S-H），morphology，cement hydration，early strength
