AERFLOW is engineered to produce a controlled low strength material (CLSM) also known as flowable fill. AERFLOW produces and air cell structure that is stable and well-distributed, consistently creating a 20-25% increase in volume. AERFLOW flowable fill is fluid by nature due to the engineered air bubble system, not excess water. The air cell structure moves like lubricated ball bearings sliding over one another.
3 oz. of AERFLOW per cubic yard of finished concrete will increase the slump of the initial mix from 1.5 inches to 7-9 inches.
