Technical requirements for application of steel slag 1 Scope This standard specifies the terms and definitions and basic requirements of the technical requirements for application of steel slag, the technical requirements for steel slag used as binders, aggregates, sintering fluxes, flue gas desulfurizers and cement raw meals, and the test methods, inspection and acceptance, transportation and storage, etc., and also includes the technical conditions and requirements for the above-mentioned different application ranges of steel slag. This standard is applicable to the steel slag used as binders, aggregates, sintering fluxes, flue gas desulfurizers and cement raw meals. 2 Normative references The following referenced documents are indispensable for the application of this document.
