摘　　要：抗压强度比能够反映再生细骨料的品质,可作为区别再生细骨料品质的技术指标.水泥品种和再生细骨料的细度模数会对强度比产生影响,在测定时需规定水泥品种并考虑细度模数的影响.笔者给出了强度比的概念和试验方法,并据此对再生细骨料进行了分类.Strength ratio of recycled mortar can be serve as a technical index to reflect the properties of recycled fine aggregate. Because strength ratio of recycled mortar is affected by cement varieties and fineness modulus of recycled fine aggregate, cement varieties should be determnad and the fineness modulus of recycled fine aggregate should be considered. The paper presents the concept and experimental methods of the strength ratio of recycled mortar, and classifies the recycled fine aggregate according to this guide line.

关 键 词：再生细骨料 再生胶砂强度比 技术指标
