Experimental characterization of sisal fibre reinforced concrete showed that incorporating fibre into the concrete mixture is beneficial. Optimum performance for a matrix having sisal fibre as reinforcement is at 3% fibre volume fraction (Vff), with 70mm fibre length (Lf) and at a water-cement ratio of 0.6. There is a load increase of 28% from the time the first crack was noticed to the time the beam finally failed and the toughness index for this beam is 2.32.
