Flowing ability of self-consolidating concrete and its binder paste phase including palm oil fuel ash

Abstract

The flowing abilities of different self-consolidating concrete (SCC) mixes and their binder paste phases including palm oil fuel ash (POFA) are presented in this paper. SCC mixes were produced with several water/binder (W/B) ratios and POFA contents. The binder pastes were formulated from their parent SCC mixes. The flowing abilities of SCC mixes were measured with respect to slump flow, T50 slump flow time, inverted slump cone flow time and V-funnel flow time. The flowing abilities of binder pastes were determined with regard to the flow times at various dosages of high-range water reducer (HRWR). The experimental results revealed that the W/B ratio, POFA content and HRWR dosage have significant influences on the flowing abilities of both SCC and binder paste. The research findings also showed that excellent correlation exists between the flowing abilities of SCC and its binder paste phase.
