Abstract

Increase of globalization and urbanization increases the construction of infrastructure, roads and buildings. Relatively, demand on its raw materials such as fine aggregates (River sand) and cement also getting increased for carrying out the construction activities. In this research of looking alternative to use sustainable materials as a replacement to fine aggregates and cement, using of Granulated Blast Furnace Slag(G.B.S) as a partial or complete replacement with fine aggregates and Ground Granulated Blast Furnace Slag (G.G.B.S) as a partial replacement makes the concrete more sustainable.

The present experimental study focuses on replacing the river sand with G.B.S sand in various concrete proportions as partial replacement to river sand and to examine the engineering properties of concrete. Additionally, the study extends to replacing Ordinary Portland Cement with at various levels of replacements in G.B.S sand concrete to obtain the optimum replacement level for getting the desired parameters during fresh and hardened state of concrete.

Complete replacement of river sand with G.B.S shows better workability and while increase in replacement of cement with G.G.B.S shows better workability. Compressive strength of concrete decreases while replacing river sand with G.B.S 50% and with 100%, but the increase in replacement of cement with G.G.B.S increases the compressive strength of concrete, notably with 50% replacement shows better results than conventional concrete. Similarly, increase in G.G.B.S replacement in G.B.S concrete increases the split tensile strength of the concrete.

In the usage of the industrial by products in the concrete, the properties of concrete in fresh state and hardened state show positive impact when compared with the conventional concrete. Using G.B.S and G.G.B.S in concrete solves the disposal problem as well as preserve the natural resources in the earth and reduce the carbon footprint in the atmosphere and makes concrete as sustainable. Hence it could be recommended that G.B.S sand could be used as a complete replacement of river sand and G.G.B.S could be partially replaced with Portland cement in the concrete.
