Abstract

Abstract: Increasing durability threats on existing structures made with cementitious composites has prompted a need to find ways to improve the durability of new structures. One of the effective ways to improve the durability properties of cementitious composites is by the incorporation of fibres. A type of modified Kraft pulp fibres was employed in this study to improve the durability properties of cementitious composites. A microstructural investigation was also conducted to study the fibre morphology and its effect on the performance of the cementitious composites. Moreover, the durability tests in terms of water absorption and rapid chloride penetration were carried out. Overall results showed higher improvement of the durability of the cementitious composites with composites incorporated metakaolin, silica fume, and slag. This was further confirmed by microstructural analysis showing that these supplementary cementitious materials densified the cementitious matrix.
