Research Progress on Frost Durability of Rubber Recycled Concrete

Abstract

Rubber recycled concrete is a new type of green concrete material that partially replaces natural coarse aggregate with recycled aggregate and partially replaces fine aggregate with rubber. Recycled rubber concrete not only improves the problem of poor frost durability of recycled concrete, but also solves the problem of large amounts of waste concrete and rubber difficult to deal with, as well as a series of ecological and environmental problems caused by this. Therefore, it is of great significance to carry out the research on the frost resistance of rubber recycled concrete to promote its application in cold regions. In this paper, based on the current status of domestic and international research on the freeze-thaw damage of rubber recycled concrete, the freeze-thaw damage mechanism of rubber recycled concrete is introduced, and its influencing factors and improvement measures are discussed, so as to provide a favorable basis for the research on the freeze-thaw damage of rubber recycled concrete.
