the gel c-s-h has the trend to crystallizing and transforming into low crystallized hydrates, which were similar to tobermorite . the incorporation of mineral mixtures improves greatly the orientation of ch either in interface zone or matrix zone and the crystal sizes also become small 由于礦物摻合料的晶核作用、填充密實和二次水化作用,明顯改善了界面過渡區(qū)和基體中ch的擇優(yōu)取向,并且不論是在界面區(qū)還是基體中,結(jié)晶相的晶粒尺寸都發(fā)生了明顯的細(xì)化。
