Partial Replacement of Cement With Combination of Alccofine and Marble Dust for Development of Sustainable Concrete

Abstract

Concrete is second most consumed material in the world after water. Cement being the important material of concrete needs to be manufactured in large amount. Production of cement involves large amount of carbon dioxide emissions into the atmosphere, a major contributor for greenhouse effect and global warming. Also demand of high performance concrete (HPC) for infrastructural industry is growing. Thus, it becomes necessary to discover a partial replacement of material for cement in concrete which is environmental friendly and strength gaining which solves both issues. Leaving the waste materials to the environment directly can also cause environmental problem. Marble Dust Powder (MDP) is a developing composite material that will allow the concrete industry to optimize materiel use, generate economic benefits. Alccofine is a new generation ultra fine supplementary cementetious material as a partial replacement of cement. It also tends to gain high performance of concrete. Usage of alccofine and MDP in a combination as supplementary cementetious material (SCM) by partially replacing cement in concrete can be a leading step towards sustainable development of concrete industry. Comparing and examining the physical properties of this new modified concrete with conventional concrete is the motivation of this study.
