Abstract

The effect of hornification and hydrophobic silica (Si) coatings on the performances of plant fibre cement composites were assessed. Three macro fibres and a micro fibre, all from plant sources were used as reinforcement. Flexural results indicated that Si coated fibres increased the modulus of rupture (MOR), limit of proportionality (LOP) and modulus of elasticity (MOE) of cement composites but reduced specific energy (SE) while hornification decreased the above properties. Likewise, decreased water absorption, increased bulk density, pore volume and diameter were observed in Si coated fibre composites. Overall Si coatings on control and hornified fibres showed better pre peak behaviour in composites compared to purely hornified fibres which had a slightly better post peak performance
