Several researchers have investigated the possible use of copper slag as fine and coarse aggregates in concrete and its effects on the different mechanical and …

Here the copper slag is replaced for fine aggregate in different proportions as 40%, 60% and 80%. The effect of replacing fine aggregate by copper slag on the compressive strength of concrete and Slump of concrete were studied in this work. The properties of cement, fine aggregate, coarse aggregate and copper slag used in concrete were …

The present study evaluates the effect of utilising granulated blast furnace slag as a partial substitution of the fine fraction of natural aggregates on various concrete parameters using the general factorial approach. Two levels of the water/cement ratio (0.45 and 0.5) and four different percentages of granulated blast furnace slag (0, 20%, 40% …

The physical and chemical properties of copper slag were investigated. Copper slag, in amounts of 20, 40, 60, 80, and 100 percent, was substituted for fine aggregate in cement mortar and concrete. The fineness modulus of the combination of copper slag and fine aggregate was roughly 2.6, the optimum fineness modulus for concrete mix design.

The use of copper slag aggregate compared to limestone aggregate resulted in a 28-day compressive strength increase of about 10–15%, and a splitting tensile strength increase of 10–18% ...

DLC mixtures were designed with 150 kg/m 3 of OPC and different blends of stone dust with 20%, 40%, 60% and 80% copper slag as fine aggregate. DLC mixes were then prepared with different water contents with a view to find out the optimum water content for achieving maximum density, and corresponding compressive strength at 7 …
