Experimental Study on the Formulation of Pozzolanic Concretes According to the Physico-Chemical Parameters

These Cement additives are now recognized and accepted as desirable, even essential constituents of concrete for technical, economic ecological reasons. During cement production, a significant amount CO2 is released into the atmosphere. Global clinker production responsible approximately 7% total emissions.The use such slag, fly ash, natural pozzolan constituent can cause reduction in quantity required per tonne, hence reduced emissions. additions not only offer technical advantages to new material, but also constitute an important contribution industry. The purpose this work study physico-mechanical properties cement-based concretes, part which reinforced by Beni-Saf, very available Oust Algeria seems be it has excellent powder qualities; through comparative between some formulations pozzolanic concretes have been made different researchers, influence these on parameters order obtain best formulation apply experimentally. Slump, apparent density, compressive strength tensile bending their evolution over time various tests carried out durability with pozzolan. results found demonstrated that improves
