1) The use of copper slag in the concrete as a replacement for fine aggregate, reduces the costs of disposal, lowers the cost of the concrete and also helps in protecting the environment. 2) In this project M20 and M40 grade concrete are prepare with different ratios of copperslag instead of fine aggregate and also finding the optimum percentage of copper slag used in concrete.
can the copper slag be used instead of sand in concrete Technical Manual for the Use of Recycled Materials Generated by . use of recycled waste will act as a substitute for the materials that are conventionally purchased new .
American concrete institute used the copper slag from Bahia, Brazil as construction materials. They observed that the characteristic of the material was equivalent to the traditional ones or even better. So copper slag can be a potential alternative to the admixtures used in concrete and mortars.
Oct 11, 2018· Nonferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process. After slag is allowed to age, it can be sold for use in other industrial processes.
It can be seen from Tables 2 and 3 that the compressive strength of the mortar using copper slag is higher than the values achieved in mortars using river sand. This was proven for 3, 7 and 28 day curing times: the mortars with copper slag presented higher compressive strengths, 114%, 66% and 44%, respectively, in relation to the resistance ...
So, the present study focuses to replace sand by welding slag (WS) and furnace slag (FS) in the production of concrete. Properties of aggregates and slag were studied in detail. M25 concrete was designed for various percentages of slag, and compressive strength of concrete was found out.
title = "Copper slag as sand replacement for high performance concrete", abstract = "This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC).
(1) In this limited study it is found that river sand can be replace fully with slag sand. (2) The research scholar should take interest in its detail study particularly long term durability of concrete made with slag sand. (3) The builder should use slag sand in their construction on trial basis.
Contractors may also use copper slag in place of sand during concrete construction. Copper slag can also be used as a building material, formed into blocks. Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools.
Can The Copper Slag Be Used Instead Of Sand In Concrete. copper slag use in china Crusher manufacturers quotes can the copper slag be used instead of sand in concrete Copper Slag Suppliers Use Of DRI In EAF's Slag .
Copper slag is used in High Performance Concrete By using the copper slag in concrete as the partial replacement for fine aggregate ie, sand, the workability o f concrete increases and there by the strength of the concrete increas
