Mar 29, 2019· Today I’m going to be shared about “Project Report on Copper Slag in Concrete” With advantages and disadvantages of copper slag in concrete so let’s get started. Introduction. Traditionally soil, stone aggregates, sand, bitumen, cement etc. are used for road construction.
The workability and strength properties of the concrete with sand replaced by copper slag at an incremental of 20% by weight were assessed through a series of controlled test to determine the optimum content of copper slag replacement. Slump, compression, flexural and tensile splitting tests were carried out on 6 different mix proportions.
The feasibility of the use of copper slag and recycled concrete aggregate as substitutes for aggregates in CIR mixes was investigated. Effects of different additives such as Portland cement, FA, and RHA were studied. Copper slag and different additives improved the durability and mechanical properties of CIR mixes.
Jun 16, 2019· Slag cement blended with Portland cement first appeared in Germany in 1892, and four years later was introduced to workers in the United States. By the 1950s, the advances made in both the slag removal and the granulation processes resulted in it being used as an entirely separate product that was added at the concrete mixer.
Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is just one of many different materials that may be used as abrasive grit.
