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 由于矿物掺合料的晶核作用、填充密实和二次水化作用,明显改善了界面过渡区和基体中ch的择优取向,并且不论是在界面区还是基体中,结晶相的晶粒尺寸都发生了明显的细化。
