T/CSES 66-2022 Iron Waste Mineral Resource Utilization Pollution Prevention Technical Specification Concrete Prefabricated Components and Filling Adhesive Materials

Scope

Scope: This document specifies the technical requirements for pollution prevention and control during the collection, storage, transportation, and utilization of iron tailings in the production of concrete precast components and filling gel materials, as well as the limits for the leaching concentration of harmful substances and the testing rules. This document applies to the entire process of pollution prevention and control during the production of concrete precast components and filling gel materials from iron tailings. Main technical content: 1. This document defines five terms and definitions, including iron tailings, the recycling utilization of iron tailings, process units, concrete precast components, and filling gel materials. 2. This document proposes technical requirements for pollution prevention and control during the collection, storage, and transportation of iron tailings, such as taking measures to prevent dust, seepage, and loss in the collection and storage areas of iron tailings, and adopting measures such as sealing and covering during the transportation process to prevent dust dispersion, leakage, and spillage. 3. This document proposes pollution prevention and control requirements for the main process units of concrete precast component production, including mold processing, crushing and mixing, concrete pouring, curing, and demoulding; and for the main process units of filling gel material production, including crushing and mixing, and activation. 4. It proposes limits for the leaching concentration of harmful substances (arsenic, lead, cadmium, chromium, copper, nickel, zinc, and manganese) in concrete precast components and filling gel materials, as well as testing rules.
