An Experimental Investigation on Partial Replacement of Cement by Glass Powder in Concrete
Non degradable wastes has been a major issue now in the 21st century as more and more of these wastes are piling up in our world today and being disposed of in landfill areas without being recycled. These wastes take up a very long period of time to decompose. Because of this problem, researches have been done to fully utilize these wastes as the final products for construction materials such as concrete. Increasing emphasis on the use of sustainable materials in construction has led to the use of variety of cement replacement materials in concrete. One such material, with an underutilized potential is glass powder, given the vast amounts of glass that is present in the solid waste stream of any major city. This paper summarizes information on the mechanical durability properties of cementitious systems containing a fine glass powder. It is shown on this paper that concrete mixtures could be proportioned to achieve similar or higher compressive strengths. A better understanding of the performance of a non standard cement replacement material such as glass powder could lead to increased usage of this material, consequently contributing to sustainability.
