Abstract

Combining copper slags with the mixture of cement and sand at a particular ratio can be a way of disposing abundant amount of harmful waste copper slags. In this solidification and stabilization procedure, ultimate compression strength, curing time, and leachability are the major factors that must be considered. Applying this procedure to waste copper slags with cement as binding agent and sand as the supplementary aggregate, it was found that replacing some sand with copper slags for up to 35 wt % copper slags while maintaining 50 wt % of cement produces concrete blocks that meet the minimum strength requirement of concrete pavements when subjected to Ultimate Compressive Strength (UCS) Test. Furthermore, copper leaching was not observed in the concrete molds even though the untreated copper slags produced 3.93 ppm copper concentration in the leachate when subjected to Toxicity Characteristic Leaching Procedure (TCLP). Savings on material costs in concrete production could also berealized when copper slags replaces some of the sand aggregates. These shows that solidification and stabilization procedure is a feasible disposal procedure for copper slags.
