Copper slag is an industrial by-product generated during extraction and refining of copper metal from
copper ore. Presently there are limited uses of copper slag and unused quantity is dumped unattended in the landfills,
which create pollution in the environment. Particle size analysis of copper slag shows that it can be a substitute for
fine aggregate in the concrete during construction of rigid pavements. The principal objective of this research is to
assess the possibility of using copper slag in the construction of rigid pavements.
The cement concrete so investigated can be utilized as the wearing course of rigid pavements on the low volume roads.
Also concrete containing copper slag can be utilized for flooring of causeway, construction of median strip etc. Bulk
utilization of copper slag in the rigid pavements can reduce the cost of construction. It might be a step towards
sustainable construction of green highways.
