    Abstract

    Carbon dioxide sequestration is crucial so targets for limiting global warming can be achieved. This paper discloses results of an investigation concerning the performance of fly ash/waste glass alkaline-based mortars with recycled aggregates reinforced by hemp fibres exposed to accelerated carbon dioxide curing. Mechanical properties were studied on it. The results show that hemp fibres lead to a reduction on mechanical properties but not as high as reported by others. The results also show that 6% hemp fibre is the maximum content for masonry applications. A high correlation was found between compressive and flexural strength. Regarding the numerical results obtained with the finite element method simulation, its noticed that the FE models had good accuracy to capture the flexural performance of the beams.
