Effect of Super plasticizer for Improvement of Concrete ...

The superplasticizers (SP) are referred to as high range water reducing admixture by ASTMC494, which mainly disperses the water in concrete matrix. This property is some time called as dispersion-fluidification property of concrete admixture.

Effect of Super plasticizer for Improvement of Concrete ...

High performance concrete is a concrete mixture, which possess high durability and high strength when compared to conventional concrete. This concrete contains one or more of cementious materials such as fly ash, Silica fume or ground granulated blast furnace slag and usually a super plasticizer. The use of some mineral and chemical admixtures like super plasticizer enhance the strength ...

Effects of Super Plasticizers on Concrete Concrete ...

Hence super plasticizers enhance the durability of concrete. Super plasticizers due to the reduction in water/cement ratio, reduce the penetration of chlorides and sulphates into the concrete and thus improve the resistance to the sea water or deicing effect.
