Utilization of Copper Slag in Self-compacting Concrete - Strength and Permeation Properties

Abstract

The aim of this research was to prepare and evaluate the properties of self-compacting concrete mixes by replacing fine aggregates with copper slag. Copper slag is an industrial by-product of copper manufacturing industry. Various concrete mixes with constant water to- binder (w/b) ratio of 0.42 were produced, and the replacement level of fine aggregates by 0%, 20%, 40% and 60% copper slag were utilized for the purpose of evaluating the performance of SCC. The mechanical and the chloride migration property of the self-compacting concrete mixes were determined after 28 days of standard curing period. The fresh properties of SCC mixes were also studied. Results indicated that the properties of self-compacting concrete could be highly enhanced incorporating copper slag but in selective percentage of fine aggregate.
