Read moreCONCLUSIONS Copper slag can be used as an alternative to natural sand in concrete. When copper slag(CS) is replaced with equivalent weight because of the fact more mortar is there to surround the aggregate therefore may workability will increase in terms of slump, however the compaction factor is more or less same comparable to that of the ...
Read moreAlso known as Iron Silicate. Also a by-product, Copper Slag is made of granulated slag from a Copper Smelting process. During smelting, impurities in the copper become slag which floats to the top of the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as blasting media.
