Abstract:The metallization modification method is a new method of rubber concrete modification. We use compressive strength,flexural strength,and load-deflection tests to study the modification effect of mechanical,bending,and deflection properties of rubber concrete by the metallization modification method,and compare and analyze the modification effect between the metallization modification method and the traditional modification methods such as styrene-butadiene latex and coupling agent. The results show that the metallization modification method can greatly improve the bending toughness of concrete. The mid-span deflection of metallization modification rubber concrete grows 530% than that of unmixed rubber concrete,compares to the unmodified rubber concrete 28 d compressive strength increases by 40%,and flexural strength increases by about 25%. The metallization modification method in the mechanical property of concrete,bending deformation,and other aspects of the modification is better than the butyl rubber latex,coupling agent,and other traditional modification methods. The mid-span deflection increases by up to 320%,28 d compressive strength decay rate decreases by about 50% to 75%.
