Strength Development and Durability Properties of Concrete Containing Pre-Soaked Rice Husk Ash
Concrete at water-cement (w/c) ratio of 0.30 and 0.35 containing rice husk ash (RHA) at a low specific surface presoaked with equal weight of water wascured in water and ambient air (uncured). The RHA was presoaked in equal mass of water prior to mixing to reduce water demand in fresh concrete usually associated with concrete containing RHA. The aim was to determine the optimum ordinary Portland cement (OPC) replacement with RHA resulting from the reactivity of presoaked RHA and the effects ofdoi:10.2478/cons-2013-0001 fatcat:vhsia7bbybfpnixm6w36sdiwy4
