ABSTRACT

Concrete is a major construction material, which is usually made by mixing cement, water, fine and coarse aggregate and sometimes admixtures in their right proportions. The use of waste materials with pozzolanic properties in concrete production is a becoming a worldwide practice. The assessment of the pozzolanic activity of cement replacement materials is becoming increasingly important because of the need for more sustainable cementing products. In this bamboo leaf Ash is used as partial replacement for cement in ranges of 5%, 10% 15%. Strength and durability tests were carried out to assess the feasibility of using bamboo leaf ash as partial replacement of cement in concrete. This showed that BLAsh has no significant effect on the density of the concrete comparatively. The strength values at different ages for BLAsh replacements compare to be a bit favorable with the control of 0% BLAsh replacement. The optimum compressive strength of 20.00N/mm2 was obtained at 5% replacement at 28 days of age compared to the control of 20.00N/mm2. It is therefore advisable to use 5% replacement of BLAsh with cement paste when it is to be used as supplement to cement.
