An Experimental Study on the Mortar Compressive Strength According to Fineness and Replacement Rate of Limestone Powder

Cement industry emits as much as about 8% of global carbon dioxide emissions, so it is necessary to develop new technologies that can effectively reduce carbon dioxide emissions to prevent global warming and to maintain industry competitiveness. The supplementary cementitious materials that can replace clinkers are limited to fly ash and blast furnace slag in Korea, but various materials such as limestone and calcined clay have been used in other nations. In this study, the characteristics of limestone powder mixed cement were reviewed in consideration of the limestone powder manufacturing process.
