Abstract
In this study, the effects of the use of blast furnace slag, ground basaltic pumice andblast furnace slag + ground basaltic pumice as mineral admixtures on durability of concretepipes were investigated. Blast furnace slag, ground basaltic pumice, and equal amount of blastfurnace slag and ground basaltic pumice were used in 5, 10, and 15 % by weight in place offine aggregate in mixes. Durability of concrete pipes has been tested according to the standardprocedures (TS 821, EN 1916). Sulfate resistance and permeability of reference specimen andspecimen with admixtures were investigated. It was observed that the ultimate load ofspecimens depends on type and percentage of admixtures. The maximum ultimate load wasobtained in concrete specimens containing 5% blast furnace slag and 5% ground basalticpumice, which was 20% larger than that of the reference concrete specimens. Furthermore,concrete specimens with 10% ground basaltic pumice were found to have highest sulfateresistance
