produce HPC. Thus this study is focusing to have review on the use of copper slag as sand replacement in the production of high performance concrete. LITERATURE REVIEW . Fresh Concrete Properties . Due to low water absorption characteristics, workability of HPC was found to increase with the increase in the % of copper slag.

Effects of Copper Slag as a Replacement for Fine Aggregate on ...

the possibility of using CS as a replacement for coarse aggregate and reported an improvement in the mechanical properties of the high strength concrete mixture. Al-Jabriet al. (2009a) investigated the use of CS as a replacement for sand in high performance concrete (HPC) with a constant water content. They

Sustainability of Concrete Using Copper Slag as Replacement ...

Copper slag produced during the matte smelting and refining of copper ore, during which, the iron present in the copper concentrate combines chemically at 1200°C with silica present in flux materials such as river sand/silica sand/ quartz fines to form iron silicate, which is termed as copper slag. The copper slag thus generated is quenched ...

Experimental Study on concrete using Copper Slag as ...

copper slag, and also to scrutinise the following: 1. To find the optimum proportion of copper slag that can be gained maximum strength and that proportion will be used as a replacement substitute material for fine aggregate in concrete. 2. To debrief the physical and chemical properties by use of copper slag for fine aggregate in concrete

hpc with ggbs and robosand - michalskimeble.pl

Copper Slag Appliions In Concrete As Fine Aggregate. Hpc made by ggbs and robosand Lebanon Performance study on ggbs concrete with robosand manufacturing sand produced from granite stone, has been used as an alternative fine aggregate that various combination have been made with different proportions of cement, ground granulated blast furn.

Use of Bamboo & Copper Slag for Replacement of Steel & Fine ...

The mix design of M25 grade of concrete gives HPC concrete when replacement of copper slag is 50%. In this case we observed that Copper slag behaves like river sand. When we use bamboo as a replacement of steel, bamboo gain almost same flexural strength compared to steel reinforced concrete.

Effect of Copper Slag As A Fine Aggregate on Properties of ...

performance of high strength concrete made with copper slag as a replacement for fine aggregate at constant workability and studied the effect of super plasticizer addition on the properties of High Strength Concrete made with copper slag. They observed that the water demand reduced by about 22% for 100% copper slag replacement.
