Abstract

Durability of concrete is an important property of concrete and suitability of incorporating copper slag based on durability is unknown. With the varying percent replacement, the best mix for concrete with copper slag and its effect are still in question. This study determined the suitability of copper slag aggregate on the durability of Type IP cementt concrete based on the sorptivity test, specifically it also determined the suitable copper slag percent with the lowest sorptivity and the effects of varying the percent replacement of copper slag. Initial sorptivity test is best used in concrete seldom exposed to water while secondary sorptivity test is used in concrete often exposed to water. Copper slag, a by-product from copper ore extraction often used in sand-blasting industry and production of abrasive tools, has characteristics of a fine aggregate. Based on the results obtained, concrete with 40% copper slag produced the lowest initial and secondary sorptivity with values 1.94 x 10'3 and 0.69 x 10'3 mm/sec° 5 respectively and it had the lowest absorption. Furthermore, concrete mixtures from 0% to 40% copper shag have decreasing sorptivity, while concrete mixtures from 60% to 100% have increasing
