Abstract: In order to solve the environmental pollution caused by waste brake shoe, and further improve the basic properties of the rubber concrete by friction reclaimed materials of waste brake-shoe (FRMWBS), the effect of this materials as fine aggregate on the compressive strength, carbonization and chloride ion penetration resistance of concrete were completed.
Rubber content in concrete are 2%, 4%, 6%, 10% and 20%, respectively; replacement of sand with FRMWBS are 0%, 5%, 10% and 15%, respectively. The XRF, MIP and SEM were employed to study the micro-structure of concrete. The results show that compressive strength
is decreased with rubber content increase, diffusion coefficient of the chloride ion is decreased by 28% when rubber content is 2%; when FRMWBS content is 5%, the Carbonization resistance of rubber concrete with 2% and 4% rubber can be improved; especially, when rubber and FRMWBS content are 4% and 5%, diffusion coefficient of the chloride ion of concrete can be decreased by 64%.
