Abstract

Agriculture farms produce a massive amount of wastes annually which represents one of the main challenges facing agriculture industry. This study attempt to link agriculture and construction industries through reusing such agriculture waste (Agro waste) in construction materials. Control low strength material (CLSM) was selected as a potential construction material that can accommodate a high percentage of agro waste. This is attributed to the fact that CLSM performance requirement is low enough to be achieved while incorporating Agro waste. Standard low strength material mixtures according to ASTM were used as reference mixtures. These mixtures were also modified by the incorporation of a fine agro waste at rates 5%,10% and 20% as a volume replacement for sand. Fresh and mechanical properties including mini-slump, water absorption, spread flow, compressive and tensile strengths, modulus of elasticity and shrinkage were evaluated for all mixtures. Results showed a reduction in mechanical properties, however, it was still within the targeted strength. In addition, the reduction in compressive strength and shrinkage has an indirect proportional to the increase in rate.
