摘　　要：以废弃混凝土为再生粗集料,适当掺入一定比例的矿渣,减弱再生粗集料对混凝土强度的不利影响,配制成强度等级为C50的再生混凝土,根据再生粗集料和矿渣的掺量比例,设计了24组配合比方案,对其和易性、抗压强度进行了试验研究。结果表明,用矿渣及再生粗集料可以配制出坍落度为175 mm、28 d抗压强度达50 MPa的再生集料绿色混凝土。Through such technical measures as using abandoned concrete for recycled coarse aggregate, mixing with suitable amount of blast furnace slag for reducing the negative influence of compressive strength to use recycled coarse aggregate, preparing recycled concrete that strength is C50. 24 sets mix design with different amount of blast furnace slag and recycled coarse aggregate is prepared for testing their workability, intensity, and compressive strength. The results show that the green concrete can be prepared by blast furnace slag and recycled coarse aggregate with the technical performance as slump is 178 cm and twenty eight days compressive strenth is over 50 MPa.
