Pozzolanic use of unconventional materials as partial replacement in sustainable concrete

Abstract

There is a lot of research being done nowadays to find substitute binders for cement that won't harm the environment. The building industry conducts these studies using criteria including economics, sustainability, and technology. When making concrete, it is crucial to employ cement substitutes. Enhancing concrete's structural performance and durability is one of the most efficient strategies to lessen the negative effects of cement. It can be done by replacing some of the cement with unconventional elements like cenosphere and pumice powder. The compressive strength, split tensile strength and flexural strength of concrete cured for periods of 7 and 28 days and investigated experimentally to understand potential for beneficial use of cenospheric material and pumice powder as partial replacement of cement in concrete. In this study, findings from the harden concrete characteristics with an appropriate cement substitution using cenosphere and pumice powder are reported. The current work is concerned with the potential for producing sustainable concrete utilising cenosphere and pumice powder in place of some cement.
