Abstract

Starting from the causes of concrete slump loss and the polymerization mechanism of different types of polycarboxylic acid water reducing agents, this paper introduces the effects of different gradient slump retaining polycarboxylic acid and water reducing polycarboxylic acid combinations in polycarboxylic acid admixtures on the fluidity of cement paste and its temporal changes, the fluidity of concrete changes over time, compressive strength, and concrete state.The experimental results indicate that slump retaining polycarboxylic acid can effectively control the loss of concrete slump and ensure construction requirements. However, excessive slump retaining polycarboxylic acid in polycarboxylic acid admixtures can lead to lagging of concrete admixtures, thereby affecting concrete quality and construction requirements.
