T/CRETA 0001-2023 The preparation of green building materials from the tailings of Baotou ebo mine with selection and smelting techniques, with a limit on radioactivity

Scope

Scope: This document specifies the radioactive limit standards for the preparation of green building materials such as microcrystalline glass, microcrystalline cast stone, permeable bricks, and cementitious materials using the metallurgical tailings from Bayan Obo Mine as the main raw materials. This document applies to inorganic non-metallic building decoration materials and main building materials that have requirements for the limit of radioactive nuclides and are prepared using the metallurgical tailings from Bayan Obo Mine as the main raw materials; Main technical content: On the basis of meeting the radioactive limit requirements for building materials stipulated in the national standard GB6566—2010 "Limit of Radioactive Nuclides in Building Materials", this document specifies more stringent limits for the radioactive nuclides in green building decoration materials and main building materials such as microcrystalline glass, microcrystalline cast stone, permeable bricks, and cementitious materials prepared using the metallurgical tailings from Bayan Obo Mine as the main raw materials, including Bayan Obo fluorite tailings, metallurgical slag from Bayan Obo Mine, and converter slag after hot quenching.
