| Abstract: | 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. |
