In this research work, the impact strength characteristic of Kenaf Fiber (KF) and Corn Cob Ash (CCA) Roofing Tiles made with varying percentages of KF and CCA was examined. The Impact test was carried out according to ASTM [1] and ASTM [2] using a manually operated impact-tester machine. Mat Lab R2013a model was used to analyze the results of the impact strength. The average impact strength obtained were 98.776, 91.904, 85.463, 79.021 and 69.144 kJ/m2 for 0, 5, 10, 15 and 20% Ash contents respectively. The impact strength remained constant at 118.530 kJ/m2 with the addition of CCA at 0, 5, 10 and 15% but decreased at 20% cement replacement at the first trial. Mathematical models were developed for predicting impact strength of KF and CCA roofing tiles using Mat Lab R2013a model. The results show that corn cob ash and kenaf fiber can be used for sustainable housing development.
