Cover Story: Vegetable fibres are a sustainable alternative to non-natural fibre-reinforced concrete (FRC). The main issues in regard to plant-based fibres are their properties’ variability and potential high biodegradability in the alkaline pH of concrete. Aiming to minimise the variability of flax and hemp fibres, this study evaluates a range of chemical surface treatments’ effects on the behaviour of fibres used for FRC. A treatment using NaOH 10% for 24 h enhanced the properties of hemp FRC and reduced the degradability in an alkaline solution. For flax fibres, a novel alternative stood out: a treatment using 1% of stearic acid in ethanol for 4 h increased the tensile by 101%, with a minor effect on the elastic modulus. FRC with the treated flax fibres reduced thermal conductivity as well as the elastic modulus, and increased residual tensile strength in addition to fracture energy. View this paper
