AbstractA literature survey is carried out on the present state of utilizing rice husk ash (RHA) to produce cementitious materials. It is found that the use of open-field burnt RHA, instead of controlled burnt RHA seems to be the most appropriate technology for developing countries even though open-field burnt RHA, to be more reactive, needs more grinding than controlled burnt RHA. Future studies should be aimed at using open-field burnt RHA in producing RHA cements. Suitable and economical methods of grinding RHA, should be searched for . Experiments were carried out to investigate the influence of burning temperatures and cooling methods on the reactivity of RHA. Test results indicated that the reactivity of RHA is considerably influenced by the burning temperatures and the cooling methods. For all range§ of temperatures investigated, RHA obtained at s0 c, improves the early compressive strengths of Portland-RHA cement mortars. However, the 28 days compressive strength of mortars in which RHA was obtained from cooling at room temperature and at 5 ํc are practically equal.
