Investigation Of Coal Bottom Ash And Glass Powder In Concrete As Partial Replacement For Sand And Cement

Abstract

The study involves varying replacement levels to understand their impact on concrete properties. To make concrete better for the environment and more efficient, we can mix in waste materials. This saves natural resources like river sand and keeps important land from getting polluted. Two examples of leftovers we can add to concrete are desolate glass powder and coal bottom ash. These accoutrements might else be thrown down, but using them in concrete is a smart way to cut down on waste and make construction more sustainable. Through quantitative analysis. the study attempts to ascertain the impacts on the concrete fusions' continuity, flexural strength, and compressive strength. Additionally, this study's main goal was to look at using them in concrete to substitute cement and sand with glass powder and coal bottom ash. In place of sand, concrete samples were made using 0%, 10%, 15%, 20%, 30%, and 40% coal bottom ash and 20% mass glass powder in place of regular Portland cement. They go through several laboratory testing, including as compressive, flexural, and workability tests. The results provide the optimal replacement fraction at which the likelihood of failure increases. Each test takes 28 days to complete and is carried out in compliance with the IS code.
