Self consolidating concrete strength


SCC does not use a high proportion of water to become fluid - in fact SCC may contain less water than standard concretes.

Instead, SCC gains its fluid properties from an unusually high proportion of fine aggregate, such as sand (typically 50%), combined with superplasticizers (additives that ensure particles disperse and do not settle in the fluid mix) and viscosity-enhancing admixtures (VEA).

SCC mix designs must maintain a tight balance; they must be fluid without segregating.

The two vital admixtures used for making SCC mixes are polycarboxylate (PCE) high-range water reducers (superplasticizers) and viscosity-modifying admixtures (VMA).

As a high compressive strength concrete, SCC delivers these attractive benefits while preserving all of concrete's normal mechanical and durability qualities.
