effects of curing on concrete with copper slag

copper slag for 28days curing. 6. The flexural strength of copper slag concrete is also maximum at 40% replacement of copper slag for 28 days of curing. So the replacement of 20% to 40% of copper slag is generally useful for better strength values in M30 grade of concrete. REFERENCES [1] Brindha, D and Nagan, S (2010).

An Experimental Investigation on Optimum Usage of Copper

Strength of Copper Slag admixture Concrete, increased due to high toughness of Copper Slag. For longer curing periods (i.e. 90-Days), no detrimental effect (i.e. Strength reversal) was observed, when using Copper Slag. Replacement of Copper Slag as fine aggregate in concrete mixes reduces the cost of concrete production. The

of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the costs of disposal and help in protecting the environment. Despite the fact that several studies have been reported on the effect of copper slag replacement on the properties of Concrete, further investigations are necessary in order to obtain a comprehensive understanding that would provide

with the effects of supplementary cementitious materials in concrete by incorporating fly ash and copper slag with a water binder ratio of 0.45. Here the conventional concrete is obtained by replacing fine aggregate with 60%, 70%, 80%, 90% copper slag and ordinary Portland cement is replaced with 20% of fly ash. From the experimental results, it is observed that high performance concrete

dimensions of the coarse aggregate, as shown in Figure 2 [4,12]. Copper pl ates which had dimension of 20 mm 150 mm were used as electrodes, and four copper plates were embedded in the concrete at intervals of 20 mm. After casting the concrete into the mold, the test specimens were cured in a


Effect of Humidity and Temperature on Properties of High

After several trials, a cement content of 450 kg/m 3 and w/b ratio of 0.33 were finalized based on 28 days compressive strength gain of HPC mix and desired workability properties (slump/flow). Thus, for making HPC mixes a cement content of 450 kg/m 3 and a w/b ratio of 0.33 were used along with optimum content of micro silica as mineral admixture. After carrying out several preliminary mix

Abstract - This paper reports the effect of concrete using copper slag as replacement of fine aggregate. In this project work, M25 grade of concrete was taken for concrete mix design. The properties and characteristics of materials for cement, fine aggregate, coarse aggregate and copper slag was studied for concrete mix design. The compressive, split tensile and flexural strength of concrete

Effects of Copper Slag as a Replacement for Fine Aggregate on the Behavior and Ultimate Strength of Reinforced Concrete Slender Columns. Use of copper slag (CS) as a replacement for fine aggregate (FA) in RC slender columns was experimentally investigated in this study. Twenty columns measuring 150 mm x150 mm x 2500 mm were tested for monotonic axial compression load until failure. The

COPPER SLAG CONCRETE BEAM AT EARLY AGE T. Ch. Madhavi1 and R. Hari Prashanth2 strength after 7 days of curing. The size of the specimen casted was 750mm x 150mm x 150mm.The test was carried out in the Universal testing machine of capacity of 40 Tons. Two point loading system was adopted for the test. The average modulus of rupture (flexural strength) was determined using the

Low-permeability concrete can be attained by decreasing the water to cementitious materials ratio of the concrete and the use of pozzolans and slag. Pozzolans and slag also increase the concrete resistivity thus reducing the corrosion rate even after it initiates. ACI 318-11, Building Code Requirements for Structural Concrete provides minimum concrete cover requirements that will help protect

Furthermore, according to the efficiency values, after 28 days strength gain of concretes, which contain blast furnace slag, had more than concretes which produced only Portland cement was understood. Positive effects of curing applications were observed on the durability test such as capillarity and conductivity because of reduction the loss of water. Performance ranking was water, wet burlap

Age of the specimen, Portland cement, GGBFS, and output parameters for 3, 7, 14, 28, 63, 90, 119, 180 and 365 day compressive strength is used as experimental parameters. Around 44 mixes and 284 experiments were conducted. K. PAZHANI, and

01.05.1989The effect of different curing conditions on the performance of alkali-activated slag (AAS) pastes, mortars, and concrete has been investigated. The temperature range is from -15 to 105 C. The storing conditions were underwater and at relative humidities of 100, 70, and 50 percent. After storing under these conditions, the compressive strengths were determined, and some microscopic and x-ray

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. Recycled concrete aggregate was found to be acceptable type of aggregate as a

The results of laboratory studies conducted to evaluate the effects of different curing conditions on the compressive strength development of concrete made with pulverized copper slag as partial replacement for ordinary Portland cement (OPC) is presented. Concrete cube specimens were made with copper slag replacing cement in the following proportions; 2.5, 5, 10 and 15% compared to the control (0%) specimen under normal laboratory conditions and cured
