Harsco 100lb Medium Black Beauty Iron horse Copper Coal Slag. Harsco 100lb Medium Black Beauty Iron horse Copper Coal Slag Mfg.Presents the experimental results of an on-going project to produce concrete with copper slag as a fine aggregate. The effect of replacing fine aggregate with copper slag on the compressive, flexural and split tensile strength of concrete are studied in this work. It was seen that for design mix (1 1.66 3.76) with w c = 0.45 and 0 to 60.
Jan 20, 2016 Copper Slag (CS) used as fine aggregate in alkali activated slag concrete (AASC). • The use of CS does not have any adverse effects on strength performance of AASCs. • Durability properties of AASCs with CS showed similar performance as that of sand. • AASCs with CS contribute to several environmental and economical benefits.Key words concrete, copper slag, generated and 24.6 mill tons of slag are generated worldwide annually. In Chile, during 2002, the existing seven The research on copper slag in concrete is mainly as substitutes in producing cement raw materials and fine aggregate in concrete at present, while few studies are on the material instead of.
CONCRETE MIX DESIGN USING COPPER SLAG AS FINE . The effect of replacing fine aggregate by copper slag on the compressive strength flexural River sand is being used as ﬁne aggregate in concrete for centuries durability properties and performance characteristics of concrete with copper slag as fine aggregate 3 5 manufactured sand with high amount of.Aug 25, 2019 Various concrete mixes with constant water to- binder (w b) ratio of 0.42 were produced, and the replacement level of fine aggregates by 0 , 20 , 40 and 60 copper slag were utilized for the purpose of evaluating the performance of SCC.
Copper slag as fine aggregate for high performance concrete. copper slag as fine aggregate on the properties of normal concrete. Akihiko and Takashi  investigated the use of slag from copper smelting as a fine aggregate in concrete. From mortar strength tests with a cement slag water ratio of 1 2 0.55, the ball milled slag.Use of copper slag as a replacement for fine aggregate is investigated. Three slender reinforced concrete columns of 150x150x2500mm were tested for monotonic axial compression load until failure. The concrete mix included ordinary Portland cement, fine aggregate, 10mm coarse aggregate and copper slag.
Nov 27, 2012 Copper slag as fine aggregate for high performance concrete. slag as fine aggregate for high performance copper slag as partial and full replacement of fine aggregate. The percentage of copper slag added by weight ranged between 10- of.Copper slag in concrete production. Copper slag is one of the by-product materials from the copper smelting. In Indonesia, around 400,000 tons of copper slag are produced per year by Freeport Company and Newmont Company . This number is a motivation for the researchers to study the copper slag as aggregate or cement replacement in concrete.
Oct 04, 2014 May 03, 2020 concrete with copper slag, the fine quartz sand aggregate content decreases from 750 kg m 3 to 0, while the fine copper slag aggregate content of increases from 0 to 750 kg m 3. For the fiber reinforced high performance concrete incorporating copper slag as fine aggregates, the volume percentage of steel fiber is 2 , as shown in.In order to blast furnace slag (GGBS-50 ) based geopolymer concrete avoid these environmental issues associated with (GPC) using mill rejected coal aggregate (Coal Washery Portland cement there is need to use some alternatives Rejects) as coarse aggregate replacement at different levels such as fly ash, ground granulated blast furnace slag (0.
May 29, 2020 25 addition of copper slag as fine aggregate in concrete gives strength compare to 30 addition of copper slag as fine aggregate in concrete REFERENCES Khanzadi M, Behnood A. Mechanical properties of high-strength concrete incorporating copper slag as coarse aggregate, Construction Build Mater Vol. 23, Issue 6, Jun. 2009, pp. 2183-2188.1.1 copper slag Copper slag is by product of the manufacture of copper. Large amount of copper slag is generated as waste worldwide during the copper smelting process. River Sand is common form of fine aggregate used in the manufacturing of concrete. However, because of increased cost and large-scale depletion of sources alternatives.
May 18, 2015 This paper reports the results of an experimental study on the high performance concrete made with copper slag as fine aggregate. The percentage of Copper SlagCS added by weight in a range viz. 0, 25, 50, 75 and 100 as a replacement of sand used in.Partial Replacement of Copper Slag as Fine Aggregate. copper slag is widely used in the sand blasting industry and in the manufacturing of abrasive tools, the remainder is disposed of without any further reuse or reclamation. The use of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the costs.
3. The slump values of copper slag blended concrete increased for all replacement level i.e., from 10 to 40 in both M-25 M-30 mixes. 4. The compressive strength of M-25 and M-30 grade of concrete increased up to 20 replacement of fine aggregates by copper slag and beyond that started decreasing. 5.Of Corrosion and Durability Characteristics of Copper Slag Admixed Concrete”,International Journal Of Civil And Structural Engineering Vol 1, No 2, pp-192-211.
