Durability Aspects of Copper Slag Admixed Concrete

Akhil G, J. Karthikeyan

Abstract


This research work reports the results of a study undertaken in enhancing properties of concrete with partial replacement of fine aggregate with copper slag. In this context an experimental investigation to study the durability effects of replacement fine aggregate (by weight) with zero, optimum (40%) and full (100%) percentages of copper slag were taken up. Durability properties like permeability, elevated temperature effect, sorptivity, water absorption were conducted along with these test Young’s Modulus and size effect ratio is also conducted. A control mixture of proportions 1:2.10:3.18 with w/c of 0.45 was designed for the M30 concrete. Fine aggregate (Sand) was replaced with 40% and 100% of copper slag as optimum and full replacement. Test results showed that the replacement of fine aggregate with copper slag reduced permeability, sorptivity and water absorption up to 100%. In addition to this Young’s Modulus and elevated temperature test gives good result at 40% replacement. These findings suggest that copper slag in the range 40% could potentially replace sand in concrete without compromising the strength and durability aspects.

Keywords: copper slag, permeability, sorptivity, water absorption, elevated temperature effect, Young’s modulus
