摘　　要：XSG固化剂为多种矿物结构的聚集体,属于常温下存在的介稳高温态物质。由于其结构的不稳定,且其晶体结构中存在有活性阳离子,所以具有水化反应活性,可以自发进行水化过程。如果水化过程生成足够数量的稳定的水化物,并且彼此连生成网状凝聚结构,随着水化物粒子的大量生成,结构会强化,转化成凝聚—结晶网,直至固化剂全部溶解水化,最终硬化固结。Solidifying agent XSG is a composite of various mineral textures.It is a substance in metastable state with high temperature at normal temperature.Because of its unstable structure and active cation existing in the crystalline structure,it has the hydration activity and hydration can react spontaneously.If sufficient number of stable hydration particles and even mesh structure are formed with hydration,the structure will be strengthened and condensed-crystallization nets will be formed with a large number of hydration particles engendered,until all solidifying agent are hydrated,and hardened eventually.
