This standard specifies the homogeneity test method for admixtures in cement concrete. This standard applies to ordinary water reducers, high-efficiency water reducers, retarded high-efficiency water reducers, early-strength water-reducers, retarded-set water-reducers, air-entraining water-reducers, early-strength agents, retarders, and air-entraining agents There are 14 kinds of concrete admixtures including pumping agent, waterproofing agent, antifreeze agent, expansion agent and quick-setting agent.
