Scope

Main technical content: The standard proposes the production process, technical requirements, and test methods for recycled sand powder, as well as a complete set of technologies for its application in mortar and concrete. For the first time, it sets requirements such as the residual slurry content, strength ratio, and additional water consumption for recycled concrete, along with corresponding test methods. This provides a technical basis for promoting the resource-efficient utilization of recycled sand powder from waste concrete.
