A Study on Effect of Mustard Husk Ash on Properties of Porous Concrete

Abstract

Abstract: Mustard Husk Ash (MHA), a by-product of the mustard oil extraction process, has gained attention as a potential supplementary cementitious material in the construction industry. The incorporation of MHA in porous concrete offers the dual benefits of waste management and sustainable construction practices. The environmental advantages of utilizing MHA, such as reducing landfill waste and conserving natural resources. The review paper synthesizes the findings from various research studies that have investigated the influence of RHA on the properties of porous concrete. The impact of different percentages of Rice Husk Ash (RHA) as a partial replacement for cement is analysed. The fresh and hardened properties of porous concrete, including workability, compressive strength, water absorption, and porosity, are examined in light of the incorporation of RHA. The review paper identifies key trends and observations from the existing literature. It discusses the influence of water content and size of coarse aggregates on the performance of RHA-based porous concrete. It also addresses the challenges and limitations associated with the use of RHA, such as its effect on the water demand and workability of concrete mixes. By synthesizing the collective findings, the review paper provides valuable insights into the effectiveness and feasibility of RHA as a sustainable alternative in porous concrete production. It identifies knowledge gaps and areas for further research, emphasizing the need for long-term durability studies and performance assessments on MHA based on porous concrete under different environmental conditions. In conclusion, this review paper contributes to the understanding of the effect of mustard husk ash on the properties of porous concrete. It underscores the potential of MHA as a viable option for enhancing the sustainability and performance of porous concrete. The comprehensive analysis serves as a valuable resource for researchers, engineers, and practitioners seeking to explore the application of MHA in porous concrete and promote environmentally friendly construction practices.
