The compatibility between cement and kenaf bast fibre and itsimprovement with various types of accelerators were investigated by observation and analysis on hydration behaviour in terms of hydration characteristics, namely, maximum hydration temperature and required time to reach maximum temperature. Five extraction methods(crude, water retting, decortication, NaOH retting and benzoate retting) , four accelerators (CaCl2, AlCl3, Na2SO4, CaO), three concentrations (2, 4and 6%) and three particle sizes (0.5, 0.8 and 4.0 mm) were used . The hydration behaviour of mixturesdemonstrated that NaOH and benzoate were unsuitable with cement. Meanwhile, CaCl2 and CaO were found to be effective accelerators for restraining inhibitory influences. In addition, 2% accelerator was available and acceptable for quick-curing cement. Particle sizes of 0.5 and 0.8 mm required addition of acceleratorsto reach maximum cement setting.
