Given its chemical and mineralogical characteristics, copper slag, a solid industrial by-product, may serve as a partial substitute for silica and hematite in raw. One of the greatest potential applications for reusing copper slag is in cement and concrete production. Many researchers have investigated the use of copper. Copper slag is a by-product obtained during the matte smelting and refining of copper. Singapore imports huge amount of copper slag to be used as abrasive.

Concrete is also the basis of a large commercial industry. Given the size of the concrete industry, and the fundamental way concrete is used copper slag cement shape the infrastructure of the modern world, it is difficult to overstate the role this material plays today [ 23 ].
Utilisation of copper slag for cement manufacture
Copper slag is used in the concrete as one of the alternative materials. The safe disposal of this waste is a lack, costly and causes environmental pollution.
The construction industry is the only area where the safe use of waste material copper slag is possible. Copper slag cement it copper slag cement introduced in concrete as a replacement material, it reduces the environmental pollution, space problem and also reduces the cost of concrete.
Experimental Study on Concrete Using Copper Slag as Replacement Material of Fine Aggregate
However, further additions of copper slag caused reduction in the strength due to an increase of the free water content in the mix. Materials and Methods Materials There are many types of concrete available, created by varying the proportions of the main ingredients below.
In this way or by substitution for the cementitious and aggregate phases, the finished product can be tailored to its application with varying strength, density, or chemical and thermal resistance properties.
Aggregate consists of large chunks of material in a concrete mix, generally a coarse gravel or crushed rocks such as limestone, or granite, along with finer materials such as sand. Copper slag cement fine aggregate used in this study is river sand conforming to grading zone II Table 1 of IS [ 6 ].
The coarse aggregate used in copper slag cement study is of angular in shape and the maximum nominal size of coarse aggregate is 20 mm and it is Conforming to Table 2 of IS [ 6 ].

Cementcommonly Portland cement, and other cementitious materials such as fly ash and slag cement, serve as a binder for the aggregate. Water is then mixed with this copper slag cement composite, which produces a semi-liquid that workers can shape typically by pouring it into a form.
The concrete solidifies and hardens to rock-hard strength through a chemical process called hydration. The water reacts with the cement, which bonds the other components copper slag cement, creating a robust stone-like material.
The good quality water is used in this study. Copper slag is an irregular, black, glassy copper slag cement granular in nature and its properties are similar to the river sand. Every ton of copper will generate approximately 2.
The chemical traces such as copper, sulphate and alumina present in the slag are not harmful Figure 1. Objective of this study Many researchers had already found, copper copper slag cement possible to use as a material in concrete.
In copper slag cement experimental study copper slag is used in concrete as replacement material of fine aggregate.
The obtained results are compared with those of control concrete made with fine aggregate [ 10 ]. Properties of materials The preliminary tests were carried out for finding the materials properties of cement, fine aggregate and coarse aggregate as per Copper slag cement [ 7 ] and IS [ 6 ].
The copper slag cement properties are given in Tables 1 and 2.
