Effect Of Copper Slag On Concrete

Effect of copper slag as fine aggregate replacement in ...

Aug 12, 2019 · When sand is replaced with copper slag beyond 40% the strength of concrete was reduced and least compressive strength of 87.18 MPa is obtained when sand is replaced with 100% copper slag because the low water absorption properties of copper slag can leave excess water in concrete, which can cause excessive bleeding at higher copper slag content.

PROPERTIES AND EFFECTS OF COPPER SLAG IN CONCRETE

Properties And Effects Of Copper Slag In Concrete 50 CONCLUSIONS 4.1 Conclusions: 1. As the percentage of copper slag increases workability increases. 2. Maximum Compressive strength of concrete increased by 34 % at 20% replacement of fine aggregate, and up to 80% replacement ,concrete gain more strength than normal concrete

Effect of copper slag as a fine aggregate on the ...

An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete. Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mixture) to 100% as fine aggregates replacement.

Effects of Copper Slag as Sand Replacement in Concrete

The slump of the concrete incorporating the copper slag as fine aggregate increased as more natural sand was replaced by copper slag. Maximum slump obtained was 40mm which occurred at the 100% copper slag replacement as compared to slump of concrete mix. In general, it can be concluded that addition of copper slag

Effect of Copper Slag on Strength of Polypropylene Fiber ...

Copper slag is one such material which can be effectively used as replacement for sand in concrete. Polypropylene fibers are included as an additive to improve the performance of concrete. In this paper, the effect of replacement of fine aggregate with copper slag in polypropylene fiber reinforced concrete is studied and the results are presented. .

Effects of Copper Slag as Partial Replacement for Fine ...

2. 17.5% increase in the compressive strength was observed for geopolymer concrete with 40% copper slag as replacement for fine aggregate due to high toughness of copper slag. Fig. 2 Compressive Strength Results 4.2. Split tensile strength. One of the indirect tension test methods for concrete is split tension …

Effect of copper slag and cement by-pass dust addition on ...

Jun 01, 2006 · This research was undertaken to study the effect of copper slag (CS) and cement by-pass dust (CBPD) addition on concrete properties. In addition to the control mixture, two different trial mixtures were prepared using different proportions of CS and CBPD.

Effect of copper slag on the mechanical strengthsof concrete

It focuses on the effect of copper slag on behaviour of concrete. This stone outlines the properties, preparation and testing and finally the results obtained from...

Effects of copper slag and recycled concrete aggregate on ...

The feasibility of the use of copper slag and recycled concrete aggregate as substitutes for virgin aggregates in CIR mixes was investigated. Effects of different additives such as Portland cement, FA, and RHA were studied. Copper slag and different additives improved the durability and mechanical properties of CIR mixes.

Effect of copper slag as a fine aggregate on the ...

An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete.

Effect of Copper Slag and Recycled Aggregate in the ...

Effect of Copper Slag and Recycled Aggregate in the Behaviour of Concrete Composite - written by B. Vigneshkarthik, S. Selsiadevi, K. Arunadevi published on 2018/07/30 download full article with reference data and citations

Effect of Ground Copper Slag on Strength and Toughness of ...

Jan 01, 1999 · The effect of ground copper slag (GCS) on the strength and fracture of cement-based materials is studied. Up to 15 percent by mass of ground copper slag was used as a portland cement replacement. The strength and fracture toughness of concrete samples were studied using closed-loop controlled compression and three-point bending fracture tests.

EFFECT OF COPPER SLAG AS SUPPLEMENTARY …

Within the cement and concrete industry, copper slag can be used as cementitious material. Looking into literature, it is seen that most researchers use rather low replacement levels up to 15 wt% [5-10]. Their conclusion is that the effect of using copper slag on compressive strength is limited and only in some cases small improvements were noticed.

Effect of Copper Slag As A Fine Aggregate on Properties of ...

performance of high strength concrete made with copper slag as a replacement for fine aggregate at constant workability and studied the effect of super plasticizer addition on the properties of High Strength Concrete made with copper slag. They observed that the water demand reduced by about 22% for 100% copper slag replacement.

Effect of different curing methods on the compressive ...

The the percentage increase in the compressive strength up to 90 days of curing for water cured specimen, compared to the solar chamber and ambient air were respectively 8.5 and 12%. This trend was similar for all percentage replacement of cement with the pulverized copper slag.

Effect of Copper Slag on Properties and Structure of ...

Sep 01, 2013 · In this paper, the effects of using copper slag wastes on hydration, gelling properties, mechanical properties, pozzolanic activity and durability aspects of concrete are studied.. It has been found that copper slag have micro pozzolanic effect in the study. The concrete batches with copper slag addition presented greater mechanical and durability performance.
