Research on green porous concrete

Abstract

This research presents a study of the compressive strength, flexural strength, coefficient of permeability and superplasticizer requriment of Porous Concrete containing fine fly. Portland cement (CT) is partially replaced with pozzolans 0, 20, 30 and 40% by weight of the cementitious materials. The results show that the high compressive strength, flexural strength and low total void ratio of Porous Concrete improves substantially with partial replacement of Portland cement with fly ash. Porous Concrete mix cement containing 20 and 30% of fly ash can be used to make cementitious materials. In addition, the use of fly ash produces Porous Concrete mix with good compressive strength, flexural strength, total void ratio and coefficient of permeability.
