A Study on Preparation of Bricks Using Copper Tailing Waste

Abstract

A Study on Preparation of Bricks Using Copper Tailing Waste In India, 4 million tons of copper tailings produce every year, out of which 25,000 tons produce in Khetri Copper Mines, Khetri, and Rajasthan. This research was undertaken to study the effects of copper mine tailings as a replacement of sand on the properties of concrete and also to bring the alternative aggregates for the future. Structural materials depend on natural aggregates; it has been depleted for the last few decades due to the excessive demand from the construction industries and increasing population.

The effects of replacing sand by copper tailings on the compressive strength of concrete, workability, water permeability and initial surface absorption values are evaluated. The water penetration and initial surface absorption decreased as the replacement of copper tailings increases. It can be concluded that copper tailings as fine aggregates in concrete is technically possible and useful.
