Effect of Fly Ash on Compressive Strength and Porosity of Self-Compacting Concrete

Abstract:

Self-compacting concrete has been produced incorporating fly ash as cement replacement. The hardened properties of this concrete in term of compressive strength and porosity are investigated. The main goal of this investigation is to observe the effect of fly ash on those properties. The range of fly ash replacement level is 50%-70% by weight of the total binder. The compressive strength self-compacting concrete is reduced when fly ash replacement level is increased. The decrease in strength is more distinctive at 28 days of age compared to that of earlier or later age. Porosity as measured by vacuum saturation method tends to increase as fly ash replacement level is increased. A good correlation exists between porosity and compressive strength.
