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 ead of 50% results in decrease in strengths. [13]
using copper slag as a replacement of fine aggregate on the strength properties. M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0% to in concrete. The test results indicate that compressive strength of concrete
copper slag can be used as a partial replacement for sand as fine aggregate in concrete up to 40% in pavement grade concrete with out any loss of cohesiveness and the compressive and flexural strength of such concretes is about 20% higher than that of conventional cement concretes of the same grade
It is recommended that 40 wt% of copper slag can be used as replacement of sand in order to obtain HPC with good It should be noted that further research work is needed to explore the effect of copper slag as fine aggregates on the properties of concrete with different cement types, silica fume sources and the degree of fines.
INFLUENCE OF COPPER SLAG AS PARTIAL REPLACEMENT OF SAND IN CEMENT CONCRETE Suresh T, Ravikumar C PG Scholar, Easa College of Engineering and Technology, Coimbatore Assistant Professor, Easa College of Engineering and Technology, Coimbatore AbstractThe development of construction materials
Properties And Effects Of Copper Slag In Concrete 47 Fineness Modulus The fineness modulus of coarse aggregates (20 mm 10 mm), sand and copper slag are,, and respectively. Table to shows the fineness modulus of 20 mm, 10 mm coarse aggregates, sand and copper slag respectively.
Aug 20, 2014· Abstract. This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering.
The mix design of M25 grade of concrete gives HPC concrete when replacement of copper slag is 50%. In this case we observed that Copper slag behaves like river sand. When we use bamboo as a replacement of steel, bamboo gain almost same flexural strength compared to steel reinforced concrete.
The compressive strength of cube specimen for different copper slag content as a replacement of sand at 7, 28, and 56 days curing period respectively is presented below. These results show an increasing profile up to 40% replacement of copper slag and then it shows decreasing profile as more copper slag .
copper slag in concrete. At present about 33 million tonnes of copper slag is generating annually worldwide among that India contributing 6 to million tonnes. 50 % copper slag can be used as replacement of natural sand in to obtain mortar and concrete with required performance, strength and durability. (Khalifa S. AlJabri et al 2011)
Copper slag, a readily available waste material from shipyards in Singapore, is a possible replacement material for a portion of the natural sand in concrete mixtures, thus sustaining the projected growth in .
Mar 25, 2015· See in the photos. Black Mountain is a copper slag dump located in Wusakile township Kitwe. Slag is ''waste'' material left over when metals are refined from ore. It is used to construct roadways and railroad beds when mixed with cement. It is also used for sand blasting, added to roofing shingles and many other usages.
92 Effects of Copper Slag as a Replacement for Fine Aggregate on the Behavior and Ultimate Strength of Reinforced Concrete Slender Columns used. Table 2 shows the mix design quantities.
Granulated Copper Slag as a patial replacement for sand. r Fifteen concrete mixes with different proportions of Granulated Copper Slag ranging from 0% (for the control mix) to were considered. All the mixes were proportioned by the method of absolute volumes considering the specific grav ity of the constituent materials.
Copper Slag is an aggressive abrasive frequently used in new steel and steel maintenance applications. Its bulk density and angular shape give it an aggressiveness that provides clean, fastcutting action, considerably increasing production rates.
Aug 04, 2018· Granulated blast furnace slag ( GBFS) has been able to replace Sand to the amount of 70%. GBFS is byproduct of steel industry hence this method is feasible at location where steel plant is located in close proximity. Copper slag is yet another r...
Effect of copper slag as a fine aggregate on the properties of cement ... Therefore, it is recommended that up to 40–50% (by weight of sand) of copper slag can be used as a replacement for fine aggregates in order to obtain a...
copper slag as partial replacement of sand. In this report, M30 grade of concrete was designed and tests were conducted with different percentage of copper slag as fine aggregate in concrete. The results indicate that workability increases with increases in the copper slag percentages. The Compressive
environmental concern but also finding a value added and meaningful substitute for natural sand. C opper slag is totally inert material and its physical properties are similar to natural sand. A laboratory study was carried out in the Institute to investigate the potential of using copper slag as a partial replacement of sand in cement concrete.
possibility of using copper slag as a replacement of sand in concrete mixtures in various percentages ranging from 0%, 20%, 40% 60%, 80% and . It was observed that, the flexural strength of concrete at 28 days is higher than design mix (without replacement) for 40% replacement of fine aggregate by Copper slag. Atul et al
and sand with copper slag to find out the maximum strength of concrete. Now we are doing this investigation by dividing the fineness ratio''s percentages as 15% of fly ash as replacement of cement and 10%, 20%, 30%, 40% of copper slag as replacement of sand. Where the replacement of cement
Use of copper slag as a replacement for fine aggregate in reinforced concrete slender columns A. S. Alnuaimi Department of Civil and Architectural Engineering, Sultan Qaboos University, Oman Abstract The use of copper slag as a replacement for fine aggregate in construction will
Copper slag as sand replacement The use of copper slag as sand substitution improves the strength and durability characteristics of high strength concrete up to 50% replacement level (AlJabri et al., 2009), increased the compressive and flexural strength of .
strength properties of copper slag as a partial replacement of sand at different levels (0%, 20% and 40%). Copper slag is a byproduct obtained during the matte smelting and refining of copper. In the present investigation it is proposed to study the engineering properties of Copper slag viz. Slump test,
