An Experimental Investigation On Optimum Usage Of Copper Slag

Experimental investigations on substitution of natural sand in concrete with copper slag and blast furnace slag P N Ojha, ... sand using copper slag is an optimum replacement. They also carried out nondestructive evaluation and found excellent concrete quality at 40% replacement levels. Rao et al. [7] conducted studies on the usage of ACBFS up to 50% replacement of natural sand in concrete ...

studied and a generalized response model was built to predict the experimental results. The optimum contents of the four independent variables were suggested as % (moisture), % (copper slag), and % (roots) with an aspect ratio of, respectively. It can be concluded from the verifiion experiments that the predicted values of the soil mechanical property are almost equal ...

Experimental Investigation on Use of Copper Slag and Recycled Aggregate as a Fine Aggregate in Concrete Ashwin Raval1, B M Purohit2, A ... At the optimum content of copper slag, 10% to 50%of recycled aggregate replaced and the concrete produced. Key words: copper slag, recycled aggregate. I. INTRODUCTION Aggregates which are used in concrete are obtained either from natural sources or .

more amount of copper slag increased, the more optimum moisture content (OMD) declined and additionally maximum dry density (MDD) of soil was on the rise, while the results of the increase in cement was quite the reverse. Moreover, an artificial neural network (ANN) model has been developed using eight input parameters including: copper slag content, cement content, water content, dry .

EXPERIMENTAL ANALYSIS Shaikh Mohtasim, Sanap 1PG Student, 2Assistant. Professor Dept. of Civil Engineering, College of Engineering Research Centre, Yeola, India Abstract The main aim of this experimental investigation is to focus on the possibilities of utilizing dolomite powder (DP) in cement and concrete production. Cement is one of the most important constituents of ...

The preparation procedure and mechanism for optimizing the BSC were studied thoroughly in this experiment. The singlefactor experimental results determined an optimum aging time of 12 h and optimum calcination particle size of 2 mm. The optimum bentonite–steel slag proportion was 5:5. The optimum Na 2 CO 3 content was 5%. The optimum ...

The optimum addition of Fe2O3 was g per 100 g nickel slag, while the desulfurization ratio was % and the rates of nikel, cobalt and copper recovery were %, %, and %, respectively. Generally in the nickel converter slag, metals are mainly in the form of sulfides, which are difficult to separate from slag. Although metal oxides in the slag, such as NiO, CoO, and Cu2O ...

obtained from experimental investigations using copper slag which is a waste by product produced during the smelting process of manufacture of concrete from its ore. Experimental investigations are carried out by replacing sand with copper slag in content of 10%, 20%, 30%, 40%, 50%, 60% and keeping all other ingredients constant. It is observed that the optimum content of copper slag that ...

copper slag shows minimum erosion rate compared to other Fig. 3. Effect of erodent temperature on erosion rate of copper slag filled composites C. Experimental Analysis Tables 3 show the erosion rates of different composites for all 16 test runs and their corresponding S/N ratios. Each of the values is in fact the average of two repliions. The analysis is made using the popular software ...

This study focused on the engineering properties of alkaliactivated slag (AAS) pastes prepared by mixing an activator consisting of sodium silie and sodium hydroxide at room temperature. The watertoslag ratio of AAS paste was kept constant at by mass. AAS pastes were prepared using the activator with five different silie moduli of 1,,,, and and three different Na ...

In order to accomplish this goal we should use a method called adsorbing. In this study the adsorption of copper ions in hydrated copper nitrate (Cu (NO3)2, 3H2O) aqueous solution on natural zeolite (Clinoptilolite) and vermiculite was studied in batch reactors. The effect of temperature (25, 50, 75 °C), solution pH () and concentration effect on the traditionally defined adsorption ...

slag replacement shows decrement of compressive strength due to excess free water, but 80% copper slag can be used with suitable admixtures[19]. This experimental study aims to use 40% (optimum percentage) of copper slag with % and %

with copper slag as a fine aggregate at constant workability and studied the effect conducted experimental investigations to study the effect of using copper slag as a replacement of fine aggregate on the strength properties and concluded that Maximum Compressive strength of concrete increased by 55% at 40% replacement of fine aggregate by copper slag and flexural strength increased by 14 % ...

experimental investigation, to study the effect of using glass powder and copper slag on the property of concrete. OPC53 cement replaced by waste glass powder and fine aggregate replaced by the copper slag. The range of replacement of glass powder with cement is 5% to 15% with an increment of every % and the range of replacement of copper slag with fine aggregate is 30% to 50% with an ...

Typical copper slag from the pyrometallurgical production of copper contains about 1 % Cu. Many times of research with the aim from recycling and reusing these slags inducted in the past few decades [113]. The one stage Outokumpu process for copper blister combines two technological operations, smelting of the copper mattes and its converting. The main advantages of this process are ...
