Copper slag. Copper slag grains have a fineness modulus of 3.4. In order to use copper slag as a mineral admixture it was necessary to carry out an experimental study associating grinding time, average diameter and pozzolanic activity assessed in mortars [].Based on this study, it was verified that 60 min was the optimal grinding time …
PROCEDURE: *About 14 litres of concrete is taken and fill the vertical section of L-BOX. *Lift the gate and allow the concrete to flow out into the horizontal section. *Start the stop watch and note down the time taken to reach 200 and 400mm marks. *When the concrete stop flowing the heights H1 and H2 are measured. …

Now a days, the application of waste material usage in building materials has increased effectively. Copper slag is a by product created during the copper smelting and refining process. This material represents a popular alternative to sand. Natural sand is used from river bed for all construction stage. Decreasing natural resources create the …
Some studies reported that GCS as a replacement of cement in SCC at 0% to 30% the flow properties are increasing and it ranges from 655 to 695 mm at water-cement ratio 0.51, and copper slag replacement is done from 0 to for the water-cement ratio of 0.45 and 0.55with conventional concrete. The slump ranges from 162 …
