EPS Polycarboxylate superplasticizer

EPS (40%)polycarboxylate super plasticizer high water content has reduced the advantages of small, can greatly reduce the water-cement ratio of concrete to improve early and late strength, can improve the physical properties of concrete, to improve permeability and crack capacity. Cementations material content is 0.8% to 1.5%, reducing the water rate can be achieved: 20% 35%.And whenby high water, low water-cement ratio in the case of improving the fluidity of cement paste and increase the slump of concrete.Slump loss, in two hours less than 15%, while the compressive strength of concrete 28d higher than 35% of the reference concrete.To comprehensively improve the main physical and mechanical properties of concrete, reduce heat of hydration of cement; significantly improve the impermeability of concrete.Have improved the workability of concrete, to improve the flow of concrete without bleeding occurs, segregation phenomena, can improve the steel and concrete bond strength.C80 high-strength concrete can be prepared or slump 20 24cm of C60 high-strength concrete or self-compacting concrete.The preparation of high-durability concrete impermeability, grade or even greater than P20 to P40. And preparation of high resistance to carbonation of concrete, Preparation of concrete with high resistance to freezing, and thawing, the freeze-thaw resistance of up to 300 times.
