The high cost and environmental damage of cement has led researchers into searching for alternative binders that are friendly and contribute to waste management. This research is set out to investigate the use of the mix of an industrial waste, Calcium Carbide Waste (CCW) and an agricultural waste, Bamboo Leaf Ash (BLA) as incomplete replacement of Portland cement (OPC) in concrete, determine the compressive strength and the workability properties of the concrete. Oxide composition analysis of Calcium Carbide Waste Powder (CCWP) and Bamboo Leaf Ash (BLA) confirmed their status as non pozzolanic material rich in Calcium oxide (CaO) component and pozzolanic material rich in Silicon oxide (SiO2), respectively using X-ray fluorescence spectrometer. The effect of Bamboo Leaf Ash (BLA) and Calcium Carbide Waste Powder (CCWP) on concrete was investigated for the replacement by addition of 5.0%, 10.0%, 15.0% and 20.0% respectively by weight of Portland cement to concrete at 7, 28 and 56 days as well as analyze the microstructural property at 28 days. The tests established CCWP and BLA as capable of successfully replacing cement in concrete production with added advantages in the properties in terms of chemical composition, strength and microstructural property.
