THE STUDY OF THE EFFECT OF PARTIALLY REPLACING COCONUT SHELL

ABSTRACT

This project work titled " THE STUDY OF THE EFFECT OF PARTIALLY REPLACING COARSE AGGREGATE WITH COCONUT SHELL" aims to investigate the feasibility and impact of using coconut shell as a sustainable alternative to traditional coarse aggregates in concrete mixtures. This research responds to the growing need for sustainable construction materials, particularly in the context of reducing the environmental footprint of the construction industry. The study employed a systematic approach, including the preparation of concrete mixtures with varying percentages of coconut shell as a replacement for coarse aggregate. Compressive strength tests were conducted on these mixtures, and the results were compared with a control group using conventional concrete. The outcomes of this study contribute to the existing body of knowledge in sustainable construction materials and provide insights into the potential benefits and limitations of incorporating coconut shell into concrete. As a result, the goal of this study is to use coconut shells in place of some of the coarse aggregate in concrete. The study discusses the performance of concrete mixes manufactured with coconut shells that have a maximum size of 20 mm and are grade C30. Common Portland Cement 42.5 grade and coarse sand were used to make standard concrete cubes. Compression strength tests were performed on concrete samples that ranged in age. According to test results, except for the C30 mix, substituting coconut shells for the standard 20mm coarse particles has no appreciable impact on the compressive strength of concrete up to 15%. But following that, as the proportion of coconut shell aggregates in concrete rose, strength gradually started to fall.
