Abstract—This paper reported on an experimental program to research the effect of using blasted copper slag from shipyard repair and maintenance as replacement of fine aggregates in the sand-cement brick. 20 cubes of cement sand brick mixtures were produced with different blasted copper slag ratio ranging from 0% (for the control mixture) to 60%. All the sand-cement brick mixtures were tested for their compressive strength, density and water absorption at day 28 of air curing. There was a 16.28% improvement in the compressive strength of brick with 20% replacement of copper slag as fine aggregates in comparison with control mixture. However, the addition of higher percentage of blasted copper slag as fine aggregates resulted in reduction of compressive strength but the density was increased. Also, the results of water absorption decreased as copper slag ratios in brick increases. The water absorption for 60% of copper slag ratio in brick was the lowest absorption compared to 20% of copper slag to sand ratio in brick. Hence, it is recommended that 0% to 20% of blasted copper slag may be used as a replacement of fine aggregates in order to obtain a good strength and low density of sand-cement brick.
