Experimental study on frost-resistance property of waste rubber aggregate concrete

The experimental using quick frozen method to study the frost-resistance property of waste rubber concrete. Sand was replaced by waste rubber at equal volume substitution ratio divided into 5%, 10%, 15% and 20%; and rubber particle diameter is divided into 2-4mm, 60-80 mesh and 30-40 mesh. The test results show that: the frost-resistance property of waste rubber concrete could meet the specification of design requirements, the antifreeze level is higher than the matrix concrete, and the frost-resistance property improve with the reduce of rubber particle size, the best substitution ratio of rubber aggregate is about 10%.
