This research project describes the impact resistance of masonry units bound with fibre-reinforced Type S mortars and hydraulic lime mortar. The dynamic impact factor and stress rate sensitivity were evaluated for the flexural strength of the mortar and the bond strength, and further, the pattern of failure was noted for each mix and loading rate. Results show that the impact resistance of the masonry units increased in the presence of fibres. However, the stress rate sensitivity of the bond strength decreased with an increase in fibre content. Also, whereas the mode of failure in those masonry units bound with plain Type S mortars was through fracture at the mortar-block interface, the addition of fibres transferred the failure plane to within the masonry block. For hydraulic lime mortar, fibre reinforcement retained the sacrificial nature of mortar and also increased the flexural toughness factor of the joint even under dynamic loading. / Structural Engineering
