The Study of Foamed Concrete with Polypropylene Fiber and High Volume Fly Ash

Abstract

The physical, mechanics, deformation, heat properties, pore structure of foamed concrete with polypropylene fiber and high volume fly ash were tested with the different water/binder ratio, perlite, foaming agent, polycarboxylate water reducer. The results showed that when adding foaming agent, PCA into foamed concrete with lower W/B ratio, it is possible to research the function integration foamed concrete with lower bulk density, higher compressive strength, smaller drying shrinkage, thermal insulation and waterproof.
