The concrete mixture included cement (OPC), fine aggregate, coarse aggregate and copper slag. The percentage of cement, water and coarse aggregate kept constant within the mixture, while the % of copper slag as a replacement for sand varied from 0% to 50%. Compressive strength test was conducted for specimens at 7, 14 and 28 days of curing of ...
Binaya Patnaik et al An Experimental Investigation on Optimum Usage of Copper Slag as Fine Aggregate in Copper Slag Admixed Concrete 3647 |International Journal of Current Engineering and Technology,, (Oct 2014) Table 1Concrete Mix Design Details – M20 Mix % of Copper Slag Copper Cement in kg Total
Copper slag, in amounts of 20, 40, 60, 80, and 100 percent, was substituted for fine aggregate in cement mortar and concrete. The fineness modulus of the combination of copper slag and fine aggregate was roughly, the optimum fineness modulus for concrete mix design. At this value, workability was found to be satisfactory with minimal bleeding.
3) Copper slag have been widely used for roofing granules, cutting tools, abrasive, road base construction, rail road ballast and cement industries. II. SCOPE AND OBJECTIVE A. Scope of the Investigation 1) To determine the behavior of concrete using Copper slag as fine aggregate. 2) To meet the scarcity of Natural fine aggregate in future, the ...
replacement of fine aggregates up to 20% by copper slag, but beyond that got decreased. On the basis of present research, it has been concluded that copper slag can be utilized by the partial replacement of fine aggregates in the tune of 20% in M25 grade of concrete. The utilization of this industrial byproduct in concrete
· Abstract. The present work focuses on assessing the viability of applying blasted copper slag, produced during abrasive blasting, as fine aggregate for Portland cement concrete manufacturing, resulting in an alternative and safe disposal method. Leaching assays showed no .
The quantities of cement, coarse aggregates (20 mm and 10 mm), fine aggregates, copper slag and water for each batch for different percentage of copper slag were weighed separately. The cement, copper slag and fine aggregates were mixed in dry form. The coarse aggregates were mixed to get uniform distribution throughout the batch.
Utilization of copper slag in cement and concrete ... Aug 01, 2008 · It was noticed that the use of copper slag as fine aggregate could greatly increase the abrasion resistance of the cement mortar (Tang et al., 2000).
Study on Utilization of Copper Slag as Fine Aggregate in Geopolymer Concrete, ... polymer called "Geopolymer" to replace the cement in concrete.
Utilization of CS for appliions such as replacement for fine aggregate ... use of CS as a replacement in cement in controlled lowstrength concrete and reported that mixes which were designed using waste material (, CS), cement, and fine aggregate yielded higher strength values than ... Fine aggregate Copper slag.
· Blasted copper slag as fine aggregate in Portland cement concrete. Dos Anjos MAG(1), Sales ATC(2), Andrade N(1). Author information: (1)Department of Civil Engineering, Federal University of Sergipe, CEP, São Cristóvão, Sergipe, Brazil.
utilization of copper slag in cement and concrete 008 many researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine 20, 2014 this work focuses on the use of copper slag, as a partial replacement of sand for use in cement ...
Utilization of Quartzite as Fine Aggregate in Concrete K. Kavitha1, V R Sankar Cheela2, Gopala Raju3* ... K. Kayathri (2014) described the effect of copper slag, fly ash and granite powder as a partial replacement in fine aggregate. ... water/cement ratio and grading of fine aggregate .
ordinary Portland cement, fine aggregate, 10mm coarse aggregate and copper slag. The ratios of copper slag to fine aggregate were 0%, 40% and 80%. Four8mm diameter high yield steel bars were used as longitudinal reinforcement and 6mm diameter mild steel bars were used as stirrups. Three
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.
the first phase physical properties of cement, aggregates, Silica Fume and copper slag were examined. In the second phase, M30 grade of concrete is chosen to perform the effective replacement of copper slag with fine aggregate by replacement levels of 0%, 25%, 50% and 75% and the behaviour of fresh and hardened properties of concrete was carried
greatest potential appliions for reusing copper slag is in cement and concrete production. Many researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine aggregates. The use of copper slag in cement
obtained when fine aggregate is replaced with copper at 40%. The least compressive strength of is obtained when fine aggregate is replaced with 100% copper slag. Now keeping this 100% copper slag mix as constant, Nano silica is replaced with cement .
