Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (2.5%) in raw mix for OPC and (35%) in manufacture of PSC. The material does not have any adverse impact on As shown in Table.1, copper slag has a high Fe content and has been used as an iron adjustment material during the cement clinker production. Since the main composition of copper slag is vitreous Dec 01, 2012 A standard w/b ratio of 0.485 according to the ASTM C 109 (guidelines was used for preparing mixtures incorporating 0%, 5% and 10% copper tailings by mass of cement as a mortar additive.These mixtures were identified as C0 for control, C5 for 5%, C5–PW for 5% addition of pre-wetted copper tailings and C10 for 10% addition level. A similar study on reuse of copper tailings was performed to obtain additive to cement mortars from copper tailings in The copper slag content of 60% is the optimum ratio as partial Al-Jabri et al. used copper slag as sand replacement for high performance concrete [6]. Al-Jabri, Taha and Al-Saidy examined the effect of copper slag as fine aggregate on the characteristics of cement mortar and concrete with experimental work [7]. Pazhani studied the mechanical properties of concrete made of copper slag [8]. and chemical properties of cement and copper tailings are also shown in Table 1. 2.3. Mixture proportions Pastes were prepared using 650 g of cement incorporating copper tailings as cement additive at 0%, 5% and 10% addition level by mass. Similarly, 361 g of cement containing copper tailings as an additive at of 0%, 5% and 10% by Copper slag is widely used in multiple types of applications, as professional blasting material, additive for different types of composite cements, roofing, concrete and mortar, additive in paving tiles industry, granular replacement for different mixtures of hot asphalt, material used for granular roof tiles production and granular base for Properties And Effects Of Copper Slag In Concrete 48 Table 2.7 Physical Properties of Coarse Aggregates, Fine Aggregates and Copper Slag Table 2.8 Chemical Analysis of Copper Slag 3 Table 2.9 Mix Proportions (Kg / m3) and Mix Ratio and tested at 7,28 and 56 days of curing in water Table 2.10 Sizes and Types of Moulds Used for
