The effect of varying different proportion of bamboo ash and lime as partial replacement for cement in mortar were studied. Bamboo stalks were collected and burned into bamboo ash in furnace. The results of the physical and mechanical properties of the cement and aggregate used were within the requirements stipulated by relevant standards. The mix proportion 1:6 was used out of which 2%, 4% of bamboo ash and 2%, 4% of lime were used to partially replace cement in the mortar. The compressive strength of most of the mortar cubes increases with curing days and their values lie within the required strength of 2.5 N/mm2 – 6.5 N/mm2 as stipulated by relevant codes. The water absorption rate was observed to increase with increase in bamboo ash and lime content, while the density decreases as the percentage of bamboo ash and lime in the mortar increases by mass. The study therefore can be concluded that in the presence of significant proportion (i.e. 4% or more) of bamboo ash the strength of mortar increased hence making it adequate for the production of masonry mortar and reduces building failure.
