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. At this value, workability was found to be satisfactory with minimal bleeding.
the copper slag can be alternatively used. 3 Vast quantities of copper slag are produced from manufacturing of copper.In our project we are using the copper slag by replacing natural fine aggregate at different percentage like 0, 20, 40, 60, 80, and 100. B. Objective of the Investigation 1 The use of copper slag in the concrete as a ...
normal concrete has better resistance to acid and sulphate attack compared to copper slag concrete. Keywords Copper Slag, Strength, Durability, H 2 SO 4 Solution, HCL Solution. 1. Introduction Copper slag is an industrial waste produced during the metal smelting process of copper production. According to ICSG International Copper Study Group,
Nov 01, 2020 In this study, copper slag and lime-activated fly ash were used for the manufacturing of cold-bonded aggregates. Cold-bonded copper slag fly ash CSFA aggregat. Search. ... The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource ...
copper slag was 2.67 amp 2.75 respectively as shown in Table 2.1. The water absorption of 20 mm coarse aggregates, sand ampcopper slag was found to be 0.609, 1.01 and 0.65 respectively. It was found that water absorption of copper slag was very low as compared with the natural sand and workability of concrete is affected due to it.
Jul 01, 2010 Copper slag is similar to sand in grading and its hard, non-absorptive, non-reactive properties make it an ideal fine filler material for concrete after it is suitably washed to remove all impurities. Even though WCS does not produce dust, it has a low crystalline silica less than 0.1 per cent that makes it an environmentally friendly product.
The aim of the research is a comprehensive evaluation of concrete using the EIPI method. In the evaluation the compressive strength of concrete and its durability properties represented by sorptivity and air permeability are taken into account. Since waste copper slag with increased natural radioactivity is used in the assessed concrete, additional evaluation is carried out taking into account ...
Conventional Concrete. Copper Slag as partial replacement of sand in SFRC and Conventional Concrete and results are compared. Objectives Investigating the developments in mechanical properties of concrete due to addition of hooked end steel fibers and replacement of copper slag with varying percentages of F.A.Strength parameters of steel fiber ...
Jun 04, 2000 Many concrete engineers are eager to find fine aggregate sources other than the traditional river and sea sand. Copper slag fine aggregate is expected to be one of the alternatives although the location where the copper slag is available is limited. In this paper, some characteristics of concrete with copper slag will be clarified.
copper slag in cement mortar. Test cubes of mortar were built according to the standard Nch 2260, Of1996 INN, 1996a in the form of prismatic bars having, dimensions of 40 x 40 x 160 mm width, height and length with mixtures of cement, water and sand. It was observed that the compressive strength of mortar using copper slag is higher
Today Im going to be shared about Project Report on Copper Slag in Concrete With advantages and disadvantages of copper slag in concrete so lets get started. Introduction Traditionally soil, stone aggregates, sand, bitumen, cement etc. are used for road construction.

Apr 07, 2018 Abstract Geopolymer concrete GPC is becoming a sustainable concrete when comparing to ordinary Portland cement OPC concrete. This investigation is mainly focused on the preliminary study on fly ash FA and ground granulated blast furnace slag GGBS based GPC using copper slag CS and vermiculite VM as fine aggregate replacement at different levels 0, 20
The copper slag has been used for cement material, sand blasting, reclamation and so on. However, most of the copper slag is stacked high as waste since the production exceeds demand. This study on the application of copper slag as fine aggregate for concrete has been started with the expectation of large amounts of consumption.
Keywords High Strength Concrete, Copper slag, fly ash. 1. Introduction High strength concrete HSC is widely used in the construction of high-performance structures such as high rise buildings, long span bridges, etc. So, it should have higher workability, good mechanical properties than those of ...
3. It is observed that up to 30 replacement of natural sand by copper slag, the flexural strength of concrete is increased by 14.and all percentage replacement of fine aggregate by copper slag the flexural strength of concrete is more than normal mix.
Aug 01, 2008 The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of copper slag is produced. This paper reviews the characteristics of copper slag and its effects on the engineering properties of cement, mortars and concrete.

Key word Concrete, Compressive strength, Copper slag I. INTRODUCTION Concrete is the best vital material for the construction of high rise buildings and many substructures. It is the widely used man-made building materials in the world. Somewhat more than a ton of concrete is created each year for every human being on the world.
Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway. When added to concrete, it makes the paved surface less porous, which minimizes problems with moisture and freezing.
The effective utilization of copper slag in such procedures may lead to reduction in the cost of disposal and leads to less environmental problems. Caijun Shi et al 2008 studied the characteristics of copper slag on the mechanical properties of cement, mortars and concrete and concluded that by the use of copper slag in cement and concrete,
