Description

technical field

[0001] The invention belongs to the technical field of strength and displacement testing, and relates to a tester, in particular to a comprehensive tester for bonding strength and slip of FRP-concrete interface. Background technique

[0002] The strength and displacement tester is a kind of electromechanical test instrument that is generally required in the civil engineering industry. It has the advantages of high precision, high stability and high efficiency. At present, fiber-reinforced concrete technology has been widely used at home and abroad. The key to this technology is the bonding effect of the FRP-concrete interface. However, the test method for the bonding strength of the FRP-concrete interface has always been difficult, especially because there is no portable on-site test equipment. Based on this problem, a simple and convenient FRP adhesive strength comprehensive tester has become a new market demand. At present, only some research institutes h...
