Experimental Study on Polycarboxylate High-Performance Superplasticizer Use in Tunnel Segment
Among the many super plasticizer, polycarboxylate super plasticizer because of its high water reduction rate, good slump, low admixing v olume and no significantly retarding have become a emphasis in the development and application. This paper through the experiment to determine super plasticizer use in project and tested the water reducing agent performance. The results show that when the defoamer admixture is 0.05%, the water-reducing agent can meet the subway segment concrete workability and mechanical property requirements. Suitable for segment concrete in actual production.
