Abstract

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