STRENGTH PROPERTIES OF CONCRETE BY THE UTILISATION …

Jun 30, 2020· When SCC mixes were developed using copper slag in varying proportions, the filling ability, viscosity and passing ability got enhanced. Slump flow varied from 685 mm to 750 mm for SCC mixes incorporating 0–60% copper slag. The glassy and smooth texture of copper slag led to the increase in slump flow and thus the flowability of SCC mixes.

What is a Copper Slag? (with pictures)

Aug 23, 2020· Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway. When added to concrete, it makes the paved surface less porous, which minimizes problems with moisture and freezing. It also makes concrete more fire resistant, and helps to slow the spread of heat and flames.
