摘　　要：采用超细粉煤灰和高效减水剂复掺配制再生混凝土,通过正交试验研究了影响再生混凝土强度的主要因素。试验结果表明:影响再生混凝土的主要因素是水灰比。选择了较优配合比,经较优配合比设计的混凝土的和易性和强度均能满足一般工程的质量要求,证明"双掺技术"是可行的,具有一定的工程实用价值。Recycled concrete is mixed by means of double-doped technology-ultra-fine fly ash and high range water reducing agent.Primary factor influencing recycled concrete strength is researched by orthogonal test.The results indicated that the primary factor is water cement ratio,at the same time,the more excellent mix proportion is found.The workability and strength of recycled concrete mixed by the more excellent mix proportion can satisfy the quality request of general engineering.It is proved that the Double-doped Technology is feasible and valuable.
