The EU28 total lime demand in 2017 was estimated at about 20 million tons, out of which about 40% are consumed in the iron and steel industry. Steel remains the major consumer after environment and construction. The lime industry is quite mature and consolidated in developed countries, with enough reserves and production to serve The limestone powder (LSP) accounts for about 75 % of the composition of Portland cement (PC). It can be used as cement replacement and in other fields and applications such as agriculture field, metal refining field, gaseous effluents field, production of glass, ceramic, mineral wool, pulp and paper, sodium dichromate and organic Effect of limestone powder on the properties of alkali

specific gravity of cement and limestone powder. Type I OPC has a specific gravity of 3.15, while that of limestone powder is 2.70. Replacing the cement with limestone powder will affect the density, and since the density affects the compressive strength of concrete, it will result in lower strength (Neville, 2011). 3.1.4. Air ContentThe major environmental impact of concrete comes from the CO2 emissions, produced during the cement manufacturing process. The main goal of this research project is to evaluate the efficiency of limestone powder as a partial cement replacement, in order to reduce energy consumption and CO2 emissions.
