Method for verifying adhesive property of BFRP polypropylene fiber coral concrete
The invention discloses a method for verifying the adhesive property of BFRP polypropylene fiber coral concrete, which comprises the following operation steps of: 1, testing the compressive strength, the splitting tensile strength and the breaking strength of a polypropylene fiber coral concrete test block by measuring the basic mechanical property; 2, enabling a BFRP polypropylene fiber coral concrete drawing test piece to be subjected to bonding performance influence factor and bond slip constitutive relation testing through a center drawing experiment, and 3, obtaining a conclusion by analyzing experimental data. The polypropylene fiber is added, so that generation of cement matrix microcracks can be controlled, stress concentration in concrete is relieved, cracks are effectively prevented from being generated and expanded, the adhesive property between the BFRP and the coral concrete can be researched, the stress process and the failure mechanism of bonding slippage of the BFRP and the coral concrete are analyzed, and a reference basis is provided for engineering application and design calculation of a coral concrete structure.
