Structural Behaviour (MOE and MOR) of Cement Fibre Composite Roofing Tiles for Sustainable Building Development
The use of imported building materials is becoming unaffordable in Nigeria, leading to housing insecurity. To this end, attentions are drifted to the diverse natural materials available such as agricultural waste and by- products for roofing tiles. However, before embracing such local innovation towards a sustainable housing security, there is need to test their structural behavior, if they could substitute the conventional building materials. Hence, this study seeks to investigate the Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) of corn cob ash (CCA) and kenaf fibre (KF) in cement composite roofing tiles. The findings of the study showed that there was not much difference in the MOE among the percentages composition of CCA and KF in cement for roofing tiles, but difference was obvious in their MOR. Hence, the CCA and KF used in the cement composition posed a significant effect on the MOR values for the 0, 5, 10, 15 and 20 percentages of CCA respectively but does not show much significant effect on the MOE values. Therefore, CCA and KF could be major substitute for the conventional building materials in roofing tiles production to reduce building costs towards ensuring sustainable housing delivery in developing countries.
