摘要
本文研究了以氟硅酸盐、铝硅酸盐、过渡元素改性化合物为主要成分的新型超缓凝剂。采用绝对升温法测定了新型超缓凝剂对大体积砼水化热放热过程。
The new kinds of super setting retarder that com posites w ith fluoslicate,alum inosillicate,and transition etem ent com pound is produced. The hydration process can be m esured by heat insulationm ethod. The as cending and descending.stages of the hydration curves are dom inated by various processesw ith different kinetics param eters respectively. And therm al cracking of the hardening concrete w ith supersetting retarder is described.
