Mechanical Strength, Voids, and Sorptivity Evaluation of Copper Slag Based Standard Concrete

Abstract

Management and proper employment of industrial waste is nowadays very essential in developing an unobjectionable environment. Using these waste products as a substitute to concrete preparing material is proving to be a better emerging solution for the problem. Copper slag is one such industrial waste, when used for a revolutionary concrete production (as an alternative to fine aggregate) provides good strength and durability. This paper deals with workability, compressive strength, split tensile strength, voids, water absorption, and sorptivity characteristic of concrete-incorporated copper slag. Copper replaces fine aggregate with five different percentages (0, 20, 40, 60, 80, and 100) to study slump value, mechanical strength, and percentage of voids, percentage, and rate of water absorption. Performance of copper slag incorporated concrete found to be superior to control specimen to produce concrete of good strength and durability.
