The percentage of copper slag added by weight ranged between 10 of sand used in concrete. For each concrete mixture, six 150mmx150mmx150mm cubes, three 300mmx150mm dia. cylinders and three 100mmx100mmx500mm prisms were cast. Density, compressive, tensile and flexural strengths were determined at 28day of curing.
Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.
For this research work, M20 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to 60%, cement of 0 to 20% in concrete.
recommended that 40% of copper slag can be use as replacement of fine aggregates. Also on the basis of obtained results the empirical relationships between the mechanical properties of concrete were established. Keywords: Cement, Copper Slag, Fine aggregate, Concrete, Compressive strength, workability and Density 1. Introduction
Bottom Ash and Copper Slag. Mix design and sample preparation Concrete mixtures with different proportions of Copper slag used as a partial or full substitute for fine aggregates were prepared in order to investigate the effect of Copper slag substitution on the strength normal concrete. Concrete

The present investigation is mainly focused on the effect of copper slag (CS) on micro, macro, and flexural characteristics of geopolymer concrete (GPC). In this study, copper slag was used as a
10/11/2014#0183;#32;1 [ 3 + Air ] x = 1m 3 10 By assuming around 3% of air voids, we will get 1m3 of concrete. [ ] 1 3 + 30 x = 1m 3 10 Therefore by multiplying the specific gravity ratio to the fine aggregate proportion we will end up with equal volume of concrete as that of control mix when copper slag used as natural sand.
24/1/2019#0183;#32;The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, Heavy metals in copper slag samples was tested by National Council for Cement and Building Materials, New Delhi as per the method given in ASTM Dd.
cement, fine aggregate, coarse aggregate and copper slag was studied for concrete mix design. The compressive, split tensile and flexural strength of concrete were studied for various replacements of fine aggregate by using copper slag that are 0%, 20%, 40%, 60%, and 80%. At 40% replacement of fine
Totally ten concrete mixtures were prepared. Five mixes containing different proportions of copper slag ranging from 0% (for the control mix) to 75%. Five mixes containing fly ash as partial replacement of cement ranging from 6% to 30% (all 5 mixes contains 50% copper slag as sand replacements) .
20/8/2014#0183;#32;The percentage of copper slag used for replacement of river sand are 0, 25, 50 and 75 %. Cement sand mortar joint thickness of 10 and 15 mm. Plaster ability of use of copper slag for partial replacement material for river sand. Use of copper slag as replacement material for river sand in cement concrete (0, 25, 50, 75 and 100 %)
corrosion process of concrete containing copper slag as mineral admixture. Mix proportions have been obtained for M30 grade control concrete as per code IS 10262:2009. Then copper slag is replaced by 20 %, 40 %, 60 %, 80 % and 100 % of sand to study the compressive strength, rapid

24/1/2019#0183;#32;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 50% shows strength improvement.
As the percentage of Copper slag in design mix as replacement increases, the density of harden concrete observed to be increased. The density was increased by 7% when replacement of Fine aggregate by copper slag. This is because weight of concrete increases with copper slag. References
% and % lower expansion than that of concrete without copper slag.[13] Arivalagan et al. (2013) reviewed that the flexural strength of the beam increased by 21% to 51% while replacement of copper slag. Another conclusion was that by using copper slag as a partial replacement for sand, strength increased up to 40% replacement level.
