An overview of the use and process for enhancing the pozzolanic performance of industrial and agricultural wastes in concrete

Abstract

The potential for improving sustainability in the building sector has led to a great deal of interest in using industrial and agricultural wastes in concrete in recent years. This study gives an overview of the use of industrial and agricultural wastes as supplemental cementitious materials in the manufacturing of concrete, emphasizing ways to improve the performance of these materials. The potential of various industrial and agricultural wastes, such as silica fume, fly ash, rice husk ash, and blast furnace slag, to enhance the workability, durability, and strength of concrete is being investigated. Pre-treatment techniques including chemical and physical treatments are talked about as ways to improve these waste materials' reactivity and efficacy in concrete mixes. Additionally, gaps in knowledge related to optimal utilization, long-term performance, alkali-silica reaction mitigation, quality control, environmental impact, and economic viability are identified, highlighting the need for further research in these areas. Overall, the use of industrial and agricultural wastes in concrete offers encouraging prospects for sustainable building methods, and research is still being done to overcome major obstacles and expand understanding in this area.
