Slag: The AllPurpose Aggregate. Slag is sometimes erroneously classified as industrial waste. In fact, this product can be recycled into valuable, versatile construction materials for green use. We utilize slag, a product of steelmaking, in versatile construction material for environmentally beneficial use.
2) Fine aggregate: Locally available river sand conforming to Grading zone II of IS: 383 –1970. 3) Copper slag: Copper slag is a byproduct material produced from the process of manufacturing copper. As the copper settles down in the smelter, it has a higher density, impurities stay in the top layer and then are transported to a water
In order to reduce depletion of natural aggregate due to construction, artificially manufactured aggregate and some industrial waste materials can be used as alternatives. Thus our project is to utilize the copper slag by the replacement for fine aggregate for maintaining economy and
rise in the use of copper metal and waste generated from copper industries during the matte smelting and refining process of copper metal is copper slag (CS). CS can be utilised as an alternative material to the natural fine aggregates. To one ton of copper metal, about obtain 2.2
Effect of copper slag as a fine aggregate on the properties of concrete 325 obtained from Seowon Co., Ltd. The copper slag was ground in the laboratory into a fine powder of the required particle sizes. The ground slag was classified according to the average particle size into three types, as shown in Fig. 1. The gradation tests conducted on

Studies on use of Copper Slag as Replacement Material for. Abstract. This work focuses on the use of copper slag, as a partial replacement of sand for use in cement
This paper reports an experimental program to investigate the effect of using copper slag as a complete replacement of sand on the property of fine aggregate. Addition of red soil in ratio 0%, 5%, 10% in cement.M25 mix design has been used.
Apr 19, 2016 · an experimental study on concrete of partial replacement of copper slag with fine aggregate. an experimental study on concrete of partial replacement of copper slag with fine aggregate.
Copper slag as fine aggregate for high performance concrete. Use of copper slag in concrete industry as replacement of cement or/and fine aggregates can have the benefit of reducing the costs of disposal and minimising environmental pollution [1,2]. Little research work has been conducted to investigate the potential use of copper slag as fine
Fresh and mechanical properties of self compacting concrete containing copper slag as fine aggregates . Rahul Sharma *, Rizwan A Khan. Dr B R Ambedkar National institute of Technology, Department of Civil Engineering, Jalandhar, Punjab, India, 144011 . A R T I C L E I N F O
proportions of copper slag replacement with sand of 0 to in concrete. It concluded that the maximum compressive strength of concrete increased by 55% at 40% replacement of fine aggregate by copper slag and flexural strength of concrete at 28 days is
Use of waste copper slag, a sustainable material Many researchers have investigated the use of copper slag in the production of cement, mortar, and concrete as mixed with lime stone powder, dust, cement replacement, use as partial replacement of coarse, and fine aggregates.
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 Testing III.
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.
of fine aggregate was chosen such that 50% of the aggregate passed the 20 mm sieve and were retained in 16 mm sieve and 50% of the aggregate passed 12.5 mm sieve and retained on 10 mm sieve. Copper slag that was used in this work as coarse and the particles ranged from 1.18 mm to 4.75 mm. Bottom ash obtained from North Madras Thermal
with copper slag. The fundamental properties of concrete using copper slag and class II fly ash as fine aggregates were investigated by Ishimaru et al (2005). It was concluded that up to 20% (in volume) of copper slag or class II fly ash as fine aggregates substitution can be used in the production of concrete.
concrete with copper slag fine aggregate", The 5th CANMET/ACI International conference on durability of concrete, pp 141 – 158. 5. 5.Hwang CL, Laiw JC 91989), "Properties of concrete using copper slag as a substitute for fine aggregate", The 3rd International conference on fly ash, silica fume, slag,
An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete. Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mixture) to as fine aggregates replacement.
of copper, approximately 2.2–3.0 tons copper slag is generated as a byproduct material. In Oman approximately 60,000tons of copper slag is produced every year. Many researchers have investigated the use of copper slag as fine or coarse aggregate in the preparation of cement mortar and concrete. Copper slag has been excluded from the listed
Apr 19, 2018 · Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strengthtoweight ratio, making it an effective option in concrete, or a
PDF This paper presents the experimental results of an ongoing project to produce concrete with copper slag as a fine aggregate. Sustainability and resource efficiency are becoming increasing
products as fine aggregate. Reuse of byproducts as a partial or full replacement of fine aggregate in construction activities not only reduces the demand for extraction of natural raw materials, but also saves landfill space. There are many studies reused granulate blastfurnace slag (GBFS) and copper slag (CS) as a part of fine aggregate.
