It can be seen from fig. that there is general increase in the density of both normal and high strength concretes with the increase of copper slag replacement partial replacement of cement with copper slag results slump cone test fig. variation of slump description of result from fi, the variation of slump for the partial replacement of fine aggregate with copper slag increased in the order of 53, 62, concrete using copper slag for the partial replacement of fine aggregate and were found that 30% fine aggregate can be replaced effectively. further, patil and pati studied the workability, compressive strength, split tensile strength and permeability in concrete replacing fine aggregate by copper
Get Detailsthe use of copper slag as a replacement for fine aggregate in construction will reduce damage to the environment due to the waste resulting from the copper manufacturing process and help in saving natural resources. In this research, the use of copper slag as a replacement for fine aggregate is investigated. threecoarse aggregate is found to be 2.63. 3.1.3 copper slag copper slag is one of the waste material obtained from the industry which is now behaves as a promising future for the construction industry as a fully or partial replacement of fine aggregate or cement. It is the byproduct obtained from refining of copper and matte smelting.tags: copper slag in concrete journals, experimental study on concrete using copper slag as replacement material of fine aggregate, project report on copper slag in concrete, replacement of fine aggregate with copper slag ppt, use of copper slag in cement. this post has comments.

Get Detailsjan 24, 2019 many researchers have already found it possible to use copper slag as a concrete aggregate, because copper slag has similar particle size characteristics likely to that of sand. hence the study focuses on the various percentage replacement of copper slag with fine aggregate varying from 38% to 52% at interval of 2%, since replacement of 40% to concrete can be improved by partial replacement of fine aggregate with copper slag and was found that 60% replacement gives optimum results.j. ramesh kumar, ramana studied on use of copper slag and fly ash in high strength concrete, given that concrete mixes were tested for workability, density, compressive strength, tensile partial replacement of copper slag in fine aggregate and cement reduces the cost of making concrete. replacement of copper slag increases the self weight of concrete specimens to the maximum of 8%. the initial and final setting time of copper slag admixed concrete is higher than control concrete.
