Durability properties of multiple-blended binder concretes incorporating thermally activated alum sludge ash

Research output: Contribution to journalArticle

Abstract

Binary and ternary blended binder (BBB and TBB, respectively) concretes are prepared by incorporating thermally activated alum sludge ash (AASA), silica fume (SF), ground granulated blast furnace slag (GGBS) and palm oil fuel ash (POFA) as partial cement replacement. Concrete mixtures were prepared with a water/binder ratio and total binder content of 0.30 and 493 kg/m3, respectively. The evaluated durability performances of the multiple blended binder concretes included water absorption, porosity, initial surface absorption, sorptivity and sulfate and chloride resistance (immersed in 5% sodium sulfate (Na2SO4), 5% sodium chloride (NaCl) solutions and water for 90 and 180 days). The results indicated that the BBB with 15% AASA cement replacement demonstrated superior durability performance compared with the control and 20% AASA concretes. A higher replacement level of 20% AASA did not improve inner core durability but improved surface durability characteristics. All TBB concretes performed better than the BBB concretes with AASA at the same replacement levels.
