FlowAid FA 24-2G
A viscosity modifying admixture for self compacting and high workability concretes
FlowAid is a ready-to-use liquid admixture used to modify the rheology of the concrete mix. It finds use in the manufacture of (SCC) Self compacting Concrete, Pumpable and High-Workability Concrete.
A self-compacting mix should have high workability and high viscosity. Although a superplasticizer admixture gives high fluidity, alone it does not guarantee the necessary properties to ensure a good degree of self-compacting. that is why FlowAid is a fundamental admixture when making Self Compacting Concrete and High Workability Concrete.
By using a superplasticiser alone, there is high segregation, which can lead to a improper mixed concrete. So to achieve a right balance between the fluidity & the proper placement of all the ingredients of the concrete /mortar, FlowAid is used to change the rheological behaviour of the concrete.
The fluidity of the mix is guaranteed provided there is no friction between the internal particles and the concrete can flow freely; segregation occurs when the components of the concrete separate out into mortar and large aggregates. Reaching the right balance between fluidity and resistance to segregation – apparently opposing properties – is essential for this type of mix. This balance is lacking when the fluidity of the
concrete is obtained by adding water.
The technology of using FlowAid in combination of PCE based superplasticiser of the Self Compacting Concrete range allows concretes to be placed without vibration, even when the structural reinforcement is extremely dense.
