摘要：In the last few decades, considerable research effort has been spent on the utilization of natural resources (pozzolan and limestone) as partial replacement of the Ordinary Portland cement. The benefits of addition of supplementary materials to Ordinary Portland cement are well documented. Limestone powder substitution for cement makes perfect sense in these lower w/c concretes, saving money and energy and reducing carbon dioxide emissions. The use of pozzolan powder as organic addition for mortars and concretes provided maximum compressive strength at the same workability level, comparable to that of the reference mixture after 28 days of curing. This paper describes about the properties, the mechanical strength of cement and the abrasion resistance of the concrete incorporated with limestone powder and pozzolan powder to the penetration of chloride ions. Limestone Powder and Pozzolan Powder are partially replaced with Ordinary Portland Cement for certain Percentages. Limestone powder (LMSP) and pozzolan Powder (PZNP) was used as compensating materials with different ratio of cement include 0, 5, 10, 15, 20, 30 and 40 %.
