Abstract：This article describes the development trend of liquid set accelerator，description about different quoted standard of domestic and overseas at present，reaction mechanism and classification of liquid set accelerator，etc. In engineering application，our research focus on the dosage of accelerator，water consumption per cubic concrete and slump retention ability that effect on the on-site workability，simultaneously solving problem like reducing the rebound rate in the process of construction，dissatisfied spray effect and so on.
Key words：set accelerator，liquid，technical requirement，engineering application
