摘要：
Fine aggregate can be extracted from waste concrete by series of processing. The recycled fine aggregate can then be utilized to manufacture recycled fine aggregate mortar (RFAM) or recycled fine aggregate concrete (RFAC). Air entraining agent was added in RFAM to improve its mechanical performance. The influence of the dosage of the air entraining agent on both the compressive and flexural strength of the RFAM was explored after 7 days and 28 days curing. The optimum dosage of the air entraining agent was determined.
