Research on Frost Resistance of Recycled High Performance Concrete

Abstract:

Experimental research on the frost resistance of recycled high performance concrete (RHPC) was carried out, in which three kinds of replacements were considered including recycled coarse or fine aggregate to natural coarse or fine aggregate and together. The results showed that RHPC had the lower dynamic modulus and mass loss than natural aggregate concrete when the replacement of recycled coarse or fine aggregate ranged 30-70% or 10-50%. The best frost resistance of RHPC appeared to the simultaneous replacements of 50% and 10% for recycled coarse and fine aggregate.
