Behaviour of Normal Concrete Using Superplasticizer under ...

When concrete is fresh, it is desirable to be malleable or workable. But sometimes, due to scorching conditions at site, desirable workability cannot be maintained. Then superplasticizer enhances the workability to sufficient extent by lowering the shear and flow resistance. Even in the case of self-consolidating concrete, superlasticizer greatly enhances the workability of fresh and hardened concrete

In this case, the concrete without superplasticizer gave 48% strength under C-5 whereas the same concrete with 2% superplasticizer under the same curing condition gave 60% average compressive strength to that of the respective concrete cured in C-1. This infers the positive effect of the superplasticizer in terms of strength gain if the concrete is to be exposed to higher ambient
