Evaluation of Bagasse Ash as a Substitute for Fly Ash in the Production of NAAC Blocks

This study investigates the use of bagasse ash as a partial replacement for fly ash in the production of non-autoclaved aerated concrete (NAAC) blocks. The study aimed to determine the optimal percentage of bagasse ash to replace fly ash in NAAC blocks. this study demonstrates that bagasse ash can be used as a partial replacement for fly ash in the production of NAAC blocks. However, the optimal percentage of bagasse ash to replace fly ash depends on the desired properties of the NAAC blocks. This research can provide insights for manufacturers to develop more sustainable and eco-friendly building materials. The experiment involved varying the percentage of bagasse ash in increments of 5% (0%, 5%, 10%, 15%, and 20%) to replace fly ash. The properties of the NAAC blocks produced were then evaluated based on compressive strength, water absorption, and density. The results showed that as the percentage of bagasse ash increased, the compressive strength of the NAAC blocks decreased. However, the water absorption and density of the blocks increased as the percentage of bagasse ash increased. The optimal percentage of bagasse ash for partial replacement of fly ash was found to be 20%, as it provided a good balance between water absorption, and density.
