The use of millet husk ash for cement replacement in concrete production

Abstract

The study conducted a comprehensive analysis of the potential use of Millet husk ash as a substitute for cement in concrete production. Various tests were performed to assess its suitability, including particle size distribution, slump, and compressive strength, specific gravity, and impact value tests. The research emphasized the increasing significance of considering cost implications and the potential for utilizing industrial or agricultural waste as alternative sources of raw materials for the construction industry. One of the main objectives was to investigate the effect on the compressive strength of concrete when millet husk ash partially replaces cement. This involved a detailed evaluation of the pozzolanic properties of the ash obtained from Yankaba Village of Kaura Namoda, Zamfara State, Nigeria. Furthermore, the study aimed to evaluate the mechanical and microstructural properties of concrete prepared with varying proportions of ash. The findings have substantial implications for the construction industry, particularly in terms of sustainability and cost-effectiveness. By exploring the potential use of millet husk ash as a cement replacement, the study contributes to efforts to reduce reliance on traditional raw materials and explore innovative alternatives. The comprehensive testing and evaluation provide valuable insights into the feasibility and potential benefits of incorporating millet husk ash into concrete production processes. Overall, this study represents a significant contribution to the field of construction materials and sustainable engineering practices. The insights offered are valuable for industry professionals, researchers, and policymakers aiming to promote sustainable and environmentally friendly practices within the construction sector. As the demand for sustainable construction materials continues to rise, this study offers a timely and relevant potential avenue for reducing environmental impact and enhancing the long-term viability of construction processes.
