Abstract: Ferrocement is a composite material, consisting of mortar reinforced with continuous steel-wire mesh layers. The strength, stiffness, deflection and cracking characteristics of the fer-rocement composite in flexure are affected by a number of factors, namely member thick-ness, span length, quantity and distribution of the wire-mesh reinforcement and mortar quality. This paper reports the results of an experimental investigation into the flexural be-haviour of 100mm by 500mm by 19mm ferrocement slabs with four layers of welded wire mesh reinforcement embedded in a high-strength (28-day compressive strength of 80MPa) mortar. Uncoated PVA fibres, having either 6mm or 12mm in length, with a fixed volume fraction of 0.25% were incorporated in the mortar matrix. The results showed that ferroce-ment with high-strength mortar is a highly ductility composite material and the addition of PVA fibres in mortar had improved the failure load of ferrocement but significantly modi-fied the flexural behaviour of the ferrocement by reducing the post-failure load ductility. Although the increased in the PVA fibre length from 6mm to 12mm had improved the fail-ure load of the ferrocement, it had reduced the post-failure load ductility.
