摘要: A cold-weather admixture composition that accelerates the setting time and strength development of cementitious compositions is provided which comprises the components of a soluble inorganic salt having freezing point depressing properties, an inorganic early set and strength accelerator, a polycarboxylate high range water reducing dispersant, and an organic set 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 time and strength development.
