YB/T 4230-2010 Ground lithium slag used for cement and concrete
1 Scope
This standard specifies technology and definitions, technical requirements, test methods, inspection rules, packaging, marking, transportation and storage of ground lithium slag used for cement and concrete.
This standard is applicable to lithium-magnesium powder used for cement and concrete.
Note: if lithium-magnesium powder is used in cement or concrete, the sulfur trioxide content in the cementing material shall be controlled to be no more than 4.0%.
