Study on the Properties of Concrete Incorporated With Various Mineral Admixtures ? Limestone Powder and Marble Powder (Review Paper)

C.Dhanalaxmi, Dr.K.Nirmalkumar

In the last few decades, considerable research effort has been spent on the utilization of industrial by products (marble powder) and natural resources (limestone powder) as partial replacement of Ordinary Portland cement (OPC). 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 marble powder as mineral addition for mortars and concretes, in the presence of a superplasticizing admixture 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 of Concrete Incoparted with Mineral Admixtures – Limestone Powder and Marble Powder. Limestone Powder and Marble Powder are partially replaced with Ordinary Portland Cement for certain Percentages. Limestone powder (LMSP) and Marble Powder (MBP) was used as a compensating material with different ratio of cement include 0, 10, 15, 20, 25 and 30 %.
