Improving the Performance of Cement Mortar Using Granite Powder and Nano-Silica

Abstract

The partial replacement of cement in concrete with the addition of granite Powder and nanosilica can help to increase the performance of cement mortar in concrete. The aim of the article is to investigate the performance of granite powder and nanosilica for the sustainable production of cementitious mortars. Mechanical, physical, and durability properties of these additives were first compared with the properties of cement. Afterward, a series of mortars modified with the addition of granite powder and nanosilica was made. The properties of the fresh mixes and the mechanical properties of the hardened composites were then tested. Finally, based on the obtained results, a cost analysis of the profitability of modifying cementitious composites with granite powder or flyash was investigated. We can conclude, it should be stated that both of these materials can successfully be used for the sustainable production of cementitious composites. This conclusion has a significant impact on the possibility of improving the natural environment by reducing the amount of cement production. More sustainable production of cement-based materials could enable CO2 emissions to be decreased.
