Copper slag as sand replacement for high performance concrete .Dec 18, 2017 . 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). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to .Use of Copper Slag and Fly Ash in High Strength ConcreteKeywords: 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 conventional concrete.
Mechanical Properties of Concrete with Copper Slag and Fly Ash by .copper. Copper slag is a by-product obtained from the smelt- ing and refining of copper. Production of one tonne of copper generates approximately 2.2 - 3.0 ... concretes for all concrete mixture are indicated 'excellent and good'. 3.4.2 Rebound Hammer test. In RH method, compressive strength is directly measured by.Copper slag as fine aggregate for high performance concreteHigh Performance Structures and Materials III 381 doi:10.2495/ . used as an aggregate such as excellent soundness characteristics, good abrasion .
