EXPERIMENTAL TESTING OF CFRP-ECC HYBRID FOR STRENGTHENING OF CONCRETE STRUCTURES

摘要：

　　This paper proposes a CFRP-ECC hybrid system for strengthening of concrete structures.This hybrid consists of CFRP composite embedded in the ECC matrix.CFRP functions as the main load-carrying element,while ECC acts as the adhesive layer for protecting the CFRP and transferring the load between the concrete structure and CFRP.In this paper,ECC was firstly developed which had a tensile strain capacity of 3%.Then pull-out tests were conducted to quantify the interface behavior between CFRP and ECC,and to obtain the effective bond length of CFRP.
