Using linseed oil as flax fibre coating for fibre-reinforced cementitious composite

In recent years, many studies have focused on the mix-design and characterization of cementitious composites reinforced with plant fibres. It appears that in fresh state, morphology hydrophilic nature these fibres significantly affect rheology material. hardened mechanical performances are lower than standard (glass, synthetic, etc.). These poor mainly due to weak neo-formed fibre/matrix interface. Indeed, high-water absorption capacity causes swelling/shrinkage fibre within matrix, which subsequently generates an unbounded order address issues, numerous been carried out over past few years compatibilisation treatments applied most cases, chemical leach fibre, often a significant environmental impact. This work examines influence coating treatment linseed oil flax properties composites. The first part this study deals optimisation treatment. second focuses effect composite states. results showed noticeable improvement workability treated can also improve flexural strength composite, depending mix-design. Flax slightly enhance thermal insulation
