Production of construction materials consumes a significant amount of natural resources which has a serious ecological impact. Moreover, cement production has a high carbon dioxide emission leading to environmental concerns. On the other hand, agriculture agriculture industry produces a massive amount of wastes annually which disposing it represents one of the main challenges. Hence, this study investigates the potential of producing alkali activated agro waste concrete (AAAC) “so- called cement-less agro concrete”. Different mixtures were prepared with different percentages of agro waste at rates 0%. 5%,10% and 20% as a volume replacement for sand. In addition, cement based concrete mixtures were also prepared for comparison. Fresh and mechanical properties including slump, water absorption, compressive and tensile strengths and modulus of elasticity were evaluated for all mixtures. Results showed a high potential to produce AAAC with adequate performance. The reduction in alkali activated system was low than that at cement-based system.
