Abstract
Silane coupling agent can be built a "molecular bridge" between organic molecules and inorganic molecules on the rubber surface modification, the binding ability of rubber particles and cement based materials has increased, thus improving the mechanical properties of rubber concrete. Study on silane coupling agent dosage as cementations material quality of 0.5%, the modification effect of coupling agent on the rubber concrete, compared with changes in mechanical properties of unmodified rubber concrete, and analysis the test concrete fracture pressure ratio, using the ultrasonic detector to measure ultrasonic velocity in concrete, to calculate the dynamic modulus and study its road noise performance.
