Sugarcane Bagasse Ash as Partial Replacement of Cement in Self Compacting Concrete An Experimental Investigation

Abstract

This thesis embarks on an in-depth exploration of the potential of Sugarcane Bagasse Ash (SCBA) and Pond Ash (PA) as sustainable and cost-effective alternatives in concrete production, an endeavour driven by the pressing need for more environmentally friendly construction materials. The investigation meticulously delves into the properties and preparation of SCBA and PA, emphasizing their advantageous incorporation into concrete mixtures. By conducting a comprehensive literature review and a series of experimental analyses, the study scrutinizes the durability and microstructural properties of concrete containing SCBA and PA, particularly focusing on their roles in partially replacing cement and their overall impact on concrete performance. The research undertakes detailed chemical and physical tests on both SCBA and PA, ensuring a thorough understanding of their compositional attributes and behaviour when mixed with Ordinary Portland Cement (OPC). Furthermore, Scanning Electron Microscopy (SEM) analysis is employed to observe the microstructural interactions and modifications brought about by the inclusion of SCBA and PA in OPC, providing insights into the intricate bonding and hydration processes that enhance the durability and strength of the resulting concrete. Cost analysis is another crucial component of this study, as it assesses the economic viability of integrating SCBA and PA into concrete production, considering factors such as raw material availability, processing costs, and potential savings from reduced cement usage. Beyond technical evaluations, the thesis also contemplates the broader social and environmental implications of utilizing SCBA and PA in the concrete industry. By leveraging agricultural and industrial by-products, the study highlights the reduction of waste and carbon emissions, aligning with global sustainability goals and promoting a circular economy. The research identifies challenges associated with the variability in SCBA and PA properties due to differences in source materials an
