Abstract:
Influence rules of adding single fly ash, single silica fume, and compound of fly ash and silica fume as well as age on the performance of mortar solidifying chloride were studied through chemical titration method. The results show that by comparing with the blank sample, the performance of mortar solidifying chloride, especially its chemical binding capacity of chloride is strengthened by addition of fly ash. There is hardly influence on the performance of mortar solidifying chloride by the addition of silica fume in this experiment. Appropriate addition of compound of fly ash and silica fume can further improve the performance of mortar solidifying chloride. With age increasing, performance of total amount of mortar solidifying chloride and chemical binding capacity of chloride are on the decline, but the performance of chloride physical adsorption is on the rise. Both chemical binding and physical adsorption will be invariableness when age is definite.
