Because of the product’s self leveling consistency, placing in lifts, tampering or compacting is not required. Flowable fill’s pix of Portland cement, fly ash or slag and sand can be designed to provide strengths
ranging from 50 psi (7600 psf) to be over 1000 psi.
Chemical admixtures may also be used in flowable fill to modify performance properties of strength, flow, set and permeability. In addition, stable air generators can be used to improve flexibility, lower densities/ unit weights, reduce shrinkage, bleed water and subsidence, and control strength development
in applications where future excavation is required.
