Variation of compressive strength characteristics of basic concrete with partial replacement of cement content

Abstract

Fly Ash (FA) and Waste Glass Powder (WGP) are two waste products that are being evaluated as potential cement substitutes in this study. At first, characterization of both types of waste was conducted to check the similarity index and to what extent, if any. The cement content of basic or ordinary concrete has been partially replaced by using FA and WGP. A wide range of different combinations of mix design has been used by using both wastes. In order to check the performance of newly formed concrete, compressive strength analysis has been performed. The outcomes point unequivocally in the direction of a more efficient usage of both waste for fractional replacement of cement content in concrete. Maximum rate of increase in compressive strength was observed as 21.6% for the curing age of 7 days in case of Mx design 2, whereas equal amount of FA and WGP were used to replaced partial cement content from ordinary concrete. Characterizations show that FA and WGP can both function as a cement substitute. It was also determined that the innovative possibilities opened up by the recycling of trash in the construction industry had contributed to an improved economic climate.
