Scope

Scope: This standard applies to products made from high-temperature sintered recycled fine aggregates and internal curing agents, which use surface treatment sludge, aluminum ash slag, fly ash from municipal solid waste incineration, and silica-aluminum solid waste as the main raw materials. The products are applied in high-strength concrete as internal curing agents. Radioactive substances are not applicable to this standard. This standard specifies the requirements for raw materials, production processes, product quality, testing and inspection methods, marking, storage, and transportation of high-temperature sintered recycled fine aggregates and internal curing agents for high-strength concrete. Main technical content: Preparation of high-strength concrete recycled fine aggregates and internal curing agents by sintering using surface treatment sludge, aluminum ash slag, fly ash from municipal solid waste incineration, and silica-aluminum solid waste as the main raw materials.
