ACCELERATING ADMIXTURE FOR CONCRETE

摘要

A cold-weather admixture composition that accelerates the setting time a nd strength development of cementitious compositions is provided. which compris es the components of a soluble inorganic salt harrying freezing point depressing properties, an inorganic early set and strength accelerator, a polycarboxylate high rang e water reducing dispersant, and are organic seat accelerator. With lower dosages of dispersant than those disclosed in the prior art the admixture composition provides to concrete increased dispersant performance and acceleration of setting tim e and strength development.
