description | This paper reports the results of an experimental study on the high performance concrete made with copper slag as fine aggregate. The percentage of Copper Slag(CS) added by weight in a range viz. 0, 25, 50, 75 and 100% as a replacement of sand used in concrete and cement was replaced with 15% Metakaolin. The properties studied include compressive strength, splitting tensile strength, Sorptivity, Rapid Chloride Permeability Test (RCPT), Accelerated Carbonation test and Microstructural properties. The test results showed that the compressive strength increases up to 50% copper slag as replacement of sand, beyond which decrease in strength was observed. The results of RCPT and sorptivity with different proportions of copper slag at 28, 90, 120 days of curing period showed the lowest value for the mix containing 25% and 50 % copper slag at each curing age. Carbonation results show that concrete mixes with 85% cement and MK 15% with increasing percentage of copper slag, the carbonation depth increases slowly especially for 75% and 100%. The microscopic view from Scanning electron microscopy (SEM) demonstrated more voids, capillary channels, and micro cracks with the increment of copper slag as substitution of sand as compared to the control mix, profoundly visible at 100% replacement of sand which is due to the presence of free water. |
