Article Preview

In the actual project, ECO-ECC can be used in repairing bridge deck overlay, prefabricated lightweight partitions, structural coupling beams and slab reinforcement[1][2]. The use of fiber-reinforced composite materials ECO-ECC can implement outside paste reinforcement in damaged components [3][4], supplemented by appropriate construction methods (such as jet ECC process). The high liquidity of ECO-ECC, coupled with high decentralization of micro-fiber can solve the problem of old and new concrete interface bonding and restore the using functionality and security of the structure, and extend the use life. The maximum principal stress of PC, E70, E80 and E90 is 130με, 501με, 257με and 168με. The area of maximum principal stress decreases with the thickness of strengthening layer reduces. That explains that strengthening layer provide better ductility to prevent brittle failure.
