glassy sand with 97 % of the solid granulated slag particles less than 4 mm as shown in Figure 1. Granulated BF slag is regularly used by cement industry for making portland slag cement; however conversion of this slag into fine aggregate and use as replacement of river sand is an innovative and novel approach to recycle slags.
Various proportions of copper slag replacement with sand (0%, 10%, 20%, 30%, 40% & 50%) and partial replacement of fly ash with cement 30% in concrete revealed that the compressive strength of concrete cubes with 40% replacement of fine aggregate with copper slag shows an increase of 15% when compared to the normal concrete cube.
portland cement, hydraulic lime, and sand. In the United States the formula was modified to a mix of sand with Rosendale Cement ( a high quality natural cement manu factured in Rosendale, Ulster County, New York). In 1870 Coignet's U.S. patent rights were sold to an American, John C. Goodrich, Jr., who formed the New York and Long
copper slag as a substitution replacement material of sand. Copper slag which is an industrial waste product can be used as replacement for cement with sand and contributes to the increase in various mechanical properties of concrete. Copper slag can be used up to 30% but when used ahead of 50% results in decrease in strengths. [13]
Flow or sand ratio the larger the total pressure loss of the tube with the depth decreasing amplitude the greater. (3) According to the actual pump injection procedure, the tube fluid rheological parameters will change, inject pre-flush and replacement fluid the pipe pressure loss low; inject sand mixing liquid friction pressure loss high.

Addition of up to 50% of copper slag as sand replacement yielded comparable High performance concrete Copper slag strength with that of the control mix. However, further additions of copper slag caused reduction in the Waste material strength due to an increase of the free water content in the mix.
Concrete containing cement, sand, gravel, nickel slag, water and superplasticizer were processed using normal intensive mixing. The strength of concrete is determined by the interfacial zone between binder paste and aggregates. Due to the weathering of natural aggregates with time, a morphology with rounded edges is obtained, reducing the interlocking with the paste.
Aug 23, 2017· There are a number of industrial wastes used as fully or partial replacement of coarse aggregate or fine aggregate. Some of these industrial wastes like waste foundry sand, steel slag, copper slag, imperial smelting furnace slag (ISF slag), blast furnace slag, coal bottom ash, ferrochrome slag, palm oil clinker etc are used.
