dc.description.abstractThe quest for production of cheap construction cementing material from agricultural wastes, particularly the ones with high silica content, formed the basis of this study. The process of determining the silicious material and silica content was carried out on two agricultural waste husk types, the Rice (Oryza sativa)husk and Guinea corn(Sorghum bicolor) husk to produce rice husk ash (RHA) and guinea corn husk ash (GCHA) respectively. Both husks were burnt separately in a furnace at 650 oC to produce the ash. The ash physical, chemical and cementitious properties were investigated. The particle size range of the ash was between 0.063 and 0.25mm while the silica content were 70.6 % and 79.1 % for both the RHA and GCHA respectively, at burning time of 6 hours. Their respective ash cementing property was tested by mixing their ashes with varying proportion of lime and water to form paste. The hardened paste 28th day compressive strength was 3.0 N/mm2. In comparison with common mortar, the ashes can be applied for plastering activities and block beddings.en_US
