Experimental investigation of interfacial shear behavior between Engineered Cementitious Composite and normal concrete
Source abstract
Abstract
Engineered Cementitious Composite (ECC) has received much attention due to its excellent properties of tension strain-hardening and multiple-cracking. Considering the full utilization of ECC properties and optimal cost, a kind of ECC-NC (normal concrete) composite structure has been developed and has shown great application potential. In this paper, a series of bi-surface shear tests were carried out to investigate the shear performance of ECC-NC specimens, a key factor affecting the performance of ECC-NC composite structures. The types of interfaces, including flat surface, rough surface and bubble grooves, the casting sequence and concrete strength were taken as the variables in the tests. The test results showed that the NC strength correlated strongly with the shear strength of the interface, and the effect of the casting sequence was non-negligible. Simultaneously, the formula for calculating the shear bearing capacity of bubble groove interfaces between precast NC and post-cast ECC was proposed.
