REPLACEMENT OF COPPER SLAG WITH FINE AGGREGATE

The mix design of M25 grade of concrete gives HPC concrete when replacement of copper slag is 50%. 2. In this case we observed that Copper slag behaves like river sand. 3. It is observed that when increasing percentage replacement of fine aggregate by Copper slag the unit weight of concrete is gradually increases. REFERENCES 1.

Copper slag as sand replacement for high performance concrete

Aug 01, 2009 Effect of copper slag substitute on the workability and density of HPCThe effect of copper slag replacement as fine aggregates on the workability and density of high performance concrete is presented in Table 2 for different proportions of copper slag. The workability of concrete was assessed based on the measured slump of fresh concrete.

Copper slag as sand replacement for high performance concrete

The results indicate that there is a slight increase in the HPC density of nearly 5% with the increase of copper slag content, whereas the workability increased rapidly with increases in copper slag percentage. Addition of up to 50% of copper slag as sand replacement yielded comparable strength with that of the control mix.

Use of copper slag as a replacement for fine aggregate in

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.
