with partial replacement of Fine Aggregate (Sand) with Copper Slag. Compressive Strength at the ages of 7, 28 90 days for various combinations of Copper Slag and Sand were investigated.
concrete (HSC) made with copper slag as a fine aggregate at constant workability and studied the effect. Copper slag can be used as an alternative material for coarse and fine aggregate, since it gives better performance in all the corrosion tests
with copper Slag partially replaced for fine aggregate at 20%, 40%, 60% and 80%. The SCC was prepared as per the mix design procedures stipulated by the EFNARC and it was ensured that fresh concrete satisfied all the workability properties.
Abstract. The characteristics of recycled and secondary aggregates: coarse recycled concrete aggregate (RCA), fine glass cullet aggregate (GCA) and fine copper slag aggregate (CSA), and their effects on concrete deformation properties: elastic .
copper slag was generated in the Out of the total copper slag produced in the every year, about 5070% is used as aggregate for road and pavement construction and approximately 1540% is stockpiled in copper plants and eventually landfilled at slag disposal sites.

investigate the performance of copper slag in self compacting concrete as partial replacement of fine aggregate. Therefore, it is recommended that 40% of copper slag can used as replacement of sand in order to obtain HPC with good strength and durability
already found it possible to use copper slag as a concrete aggregate. But not much research has been carried out concerning durability and corrosion studies of copper slag ... 40% copper slag for fine aggregate and 85% cement+15% copper slag for cement) in ... Physical and Chemical properties of copper slag ...
tensively used in concrete as fine aggregate. In duration about ... Copper slag :Copper slag used in this project is from Hindustan Copper Limited, Kolkata. ... Effect of CS, GBFS and Simn Substitution as Fine Aggregate on Concrete Properties Workability From Table 4, the workability of concrete increases signifi ...
Fine aggregate: Fine aggregates used for conventional concrete are river sand and copper slag. Nearby accessible sand belonging to zoneII of IS: is used. Copper slag is procured from Mythri Metallizing Private Limited, Bangalore, Karnataka, India. The physical features of fine aggregate are presented in table 3.
properties prepared with partial replacement of fine aggregates by copper slag at levels of 10%, 20%, 30%, 40%, 50% and 60%. In this study, M30 grade concrete was considered to study the strength parameters, compressive and flexural strength
silica fume at 0, 4, 8 and 12 % and fine aggregate is replaced with copper slag at 0, 20, 40 and 60 %. The results show that the use of silica fume and copper slag as replacement material improves mechanical properties of the
It is concluded that substituting 40% of fine sand with waste copper slag yields the best mechanical and durability properties. By replacing 40% waste copper slag, the compressive and bending strength of concrete increased to almost 30% and 14%, respectively. However, a slight effect was found in the total water absorption and abrasive resistance.
idea is to use copper slag as replacement of fine to several costs of labours for compaction we can go to self compacting concrete. Self compacting concrete is one of the high performance concrete which had an enormous growth in the construction industry in
The physical and chemical properties of copper slag were investigated. 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.
T1 Effect of copper slag as a fine aggregate on the properties of cement mortars and concrete. AU AlJabri,Khalifa S. AU AlSaidy,Abdullah H. AU Taha,Ramzi. PY 2011/2. Y1 2011/2. N2 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.
An investigation is carried out on the development of Self Compacting Concrete (SCC) using copper slag (CS) as fine aggregates with partial and full replacement of sand.
Effect of different types of fine aggregates on mechanical properties of concrete A review ... manufactured sand and copper slag as fine aggregate in concrete is better when replaced with natural river sand. The ... The properties of aggregate affect the durability and performance of concrete, so fine aggregate is an ...
the properties of concrete. For the experiment we have prepared five mix designs with different proportions of copper slag ranging from 0% (for the control mix) to 35% and . Concrete mixes were evaluated for density, compressive strength, ... Copper Slag As Fine Aggregate For High Performance Concrete, /HPSM060371 .
The copper slag is used as partial replacement for fine aggregate in the range of 20%, 40% and 60% by weight of sand and its optimum level is to be found.
Several researchers have investigated the possible use of copper slag as fine and coarse aggregates in normal concrete and its effect on different mechanical properties of mortar and concrete. Some studies were carried using fine powder copper slag for partial replacement of cement [6].
for copper slag infers that the gradation properties of fine aggregates at all the replacement levels are similar to the specification for sand zone II as per IS: 383. The chemical composition of slag .
