Abstract
The behaviour of masonry prisms and beams strengthened with eco-friendly ductile cementitious composite (EDCC), which is a form of engineered cementitious composite (ECC), was investigated in this thesis. Compression and out-of-plane bending tests were performed to measure compressive resistance, modulus of elasticity, and flexural capacity. It was concluded that the compressive resistance of strengthened masonry prisms remained similar in load, while ultimate stress decreased due to the increased cross sectional area. In out-of-plane bending, the strengthened concrete masonry unit (CMU) beams showed a strength increase from 11 to 26 times and the strengthened brick showed an increase from 4 to 8 times versus the beams plain counterparts. The linear strength increase was dependent on EDCC thickness, although doubling the EDCC thickness did not double the strength. Overall, masonry strengthened with EDCC is a viable alternative to ECC strengthening due to the performance and reduction in cement content.
