Studies on Concrete Incorporating Copper Slag as a Fine Aggregate

Abstract:

This paper investigates the possibility of application of copper slag as a waste byproduct from metallurgical factory Krompachy (Slovakia Republic) as a fine aggregate in concrete up to 40-50% replacement of natural filler. Results of these studies confirmed that it is possible to produce concrete with a mean compressive strength of greater 50 MPa at 28 days hardening without any special additivies. Testing of mechanical properties of concrete samples was provided on the durability point of view up to 360 days. It can be concluded from the results, that use of copper slag as fine aggregate in concrete is technically viable for road construction engineering and have some economical benefits as soon as.
