Preparation and Performance Study of Concrete Anti-segregation Agent
A concrete anti segregation agent can be obtained by compounding anionic polyacrylamide with a molecular weight of 5 million and sodium polyacrylate with a molecular weight of 6 million in a ratio of 6:4,which can effectively solve the problem of concrete segregation and layering,improve the fluidity and uniformity of concrete.This article investigates the effects of the anti segregation agent on the workability,slump loss,setting time,and compressive strength of concrete.The experimental results show that anti segregation agent W can significantly improve the flowability,slump,and time loss of segregated concrete,with little effect on setting time and a significant increase in compressive strength.
