Abstract: The impact of carbide waste,CW on the strength of concrete made with cement partially replaced with Rice Husk Ash,RHA for use in rigid pavement was investigated. Oxide composition analysis of CW and RHA confirm their status as non pozzolanic material rich in CaO component and pozzolanic materials, respectively. The large amount of space taken on landfills by waste, the constant release of environmental polluting gases like CO₂ into the atmosphere and the high cost involved in cement production has led to the search for alternative binding materials that are cheap, ecofriendly and will help contribute to waste management.

Keywords: Calcium Carbide Residue; Wood ash; Supplementary Cementitious Materials; Pozzolanic reaction; CO2 emission.
