- Synopsis:
- This paper describes test method of freeze-thaw resistance on recycled aggregate. Proposed test method measures a variation of finecess modulus(F.M.) of recycled aggregate after 10 cycles of freeze-thaw with a water bath. The F.M. variation of the test results showed good correlation to the durability factor of concrete using coarse recycled aggregates. We proposed a requirement for recycled aggregates to ensure required duarability based on the test results.
