Manufacture of artificial aggregate using alkaline solution

The construction industry's continuous quest for sustainable practices has led to the exploration of alternative construction materials that minimize environmental impact while maintaining structural integrity.Aggregate constitutes the major part of any concrete construction.Conventional aggregates are obtained directly from nature.The major problem associated with conventional aggregates is the depletion of resources.The project work describes the utilization of industrial slag which is dumped as landfill.Slag, a byproduct of various industrial processes, have emerged as promising candidates for use as construction aggregates in concrete.This study explores the feasibility of replacing traditional coarse aggregates with slag.This project aims to investigate the performance and feasibility of incorporating different types of slags, including Copper Slag (CS), and Steel Slag (GGBS), as raw material and alkaline solution as binding material in the manufacture of coarse aggregate.Through laboratory testing, mechanical properties analysis, and environmental assessments, the study seeks to provide valuable insights into the development of eco-friendly and high-performance coarse aggregate for the production of concrete.The results of the manufactured aggregate shows that the properties tested are nearer to the aggregate properties suggested by Indian standards (IS 456-2000, IS 383, and IS 9103-1999).The study also focuses on the effect of curing temperature to enhance the properties of the manufactured aggregates in the Phase-II of the project.
