Study on bonding material and bonding effect of concrete fracture members under impact load
Concrete can withstand a certain physical pressure after being bonded with epoxy resin,and the differ-ence in bonding performance determines the fracture performance of concrete in use.In this paper,the resistance of the specimens with concrete particles of different sizes to E-44 epoxy resin after fracture was studied,and the result-ing specimens were resistant to fracture under different external physical pressures and frequencies.In the experi-ment,it was found that when the external physical pressure was too high,even if the pressure was applied for a short time,the concrete specimen would still fracture.When the frequency of external pressure application was too high,the fracture of concrete specimens was also very obvious.When the particle size of the concrete was large,it was not conducive to the bonded concrete sample resisting external pressure impact.Overall,the compressive strength of concrete specimens after bonding is influenced by external pressure and the material of the concrete itself.
