摘　　要：研究了搅拌制度对动态水热合成硬硅钙石二次粒子的影响,包括硬硅钙石纤维结晶生长情况、二次粒子尺寸大小及形状、粒度分布以及C-S-H凝胶含量等。结果表明,搅拌对上述性质的影响非常显著,并且进一步影响硬硅钙石制品的干燥收缩率及体积密度。Effects of agitation on the secondary particles of xonotlite in dynamic hydrothermal process were investigated, such as the situation of fibrous xonotlite crystals, the dimension, granulometric distribution and shape of secondary particles, and the content of C-S-H. The results indicate that stirring evidently affects the formation and morphology ofxonotlite secondary particles, and further affects the dry shrinkage and bulk density of xonotlite products.
