Experimental Performance of Concrete using Sugarcane Bagasse Ash (SCBA) and Coal bottom ash (CBA)

Abstract

The fundamental aims of sustainable development are the conservation of natural resources, the reduction of environmental pollution, and the efficient use of waste materials. These aims may be achieved in concrete construction by partially replacing cement and aggregates with agrowaste such as sugarcane bagasse ash and rice husk ash, as well as industrial waste such as copper slag, steel slag, fly ash, and coal bottom ash, to name a few examples. The major goal of this study was to see how utilising Sugarcane Bagasse Ash (SCBA) as a partial substitute for cement in concrete and Coal Bottom Ash (CBA) as a partial replacement for fine aggregates affected the final product. The major emphasis of this study is on the properties of concrete, such as compressive strength and workability. Furthermore, when exposed to greater temperatures, the thermal stability of all concrete mixes is evaluated in this study. Twenty-five different concrete mixes were made with variable quantities of SCBA (0%, 5%, 10%, 15%, and 20%) replaced with cement and varying levels of CBA (0%, 10%, 20%, 30%, and 40%) replaced with fine aggregates. The ratio of water to cement in every mix was set at 0.55. Concrete's workability was assessed immediately after it was prepared, while its compressive strength was assessed 14, 28, and 60 days after it had been allowed to cure. Based on the results of the testing, it has been concluded that a blend of 10% SCBA and 10% CBA is the best option. According to the conclusions of this investigation, adding SCBA and CBA to concrete has no effect on its thermal properties.
