Influence of Coconut Shell Ash and Glass Powder as Partial Replacement of Cement in Concrete: An Experimental Study

Abstract

Abstract: The amount of garbage generated by industrial and agricultural activities on the earth's surface has given rise to concerns about the environment's sustainability and the planet's ecosystem. Because waste generation generates CO2 and other hazardous gases during disposal or manufacturing, it contributes to global warming. In this investigation, the cement is replaced by waste materials such as Coconut Shell Ash (CSA) and Glass Powder (GP). Using CSA and GP with cement replacements of 0%, 2.5%, 5%, 7.5%, 10%, and 12.5%, more than 108 specimens have been prepared in laboratory and examined. After being mix designed , the concrete is mixed in a ratio of 1:2.03:3.10 by weight of cement sand and coarse aggregate at water/cement ratio of 0.55. Initial setting, final setting time, compressive strength, split tensile strength, and flexural strength are among the qualities of concrete and cement that have been investigated.
