1 Scope
This standard specifies the test materials and requirements for the activity of industrial waste slag used as addition to cement, and the quantitative test method for the latent hydraulicity, pozzolanic feature and 28-day compressive strength ratio of cement.
This standard is applicable to the activity tests of industrial waste slag used as addition to cement, and other cement admixtures designated to adopt this method.
Note: Industrial waste slag refers to industrial waste residue outside the standards of GB/T 203, GB/T 1596 and GB/T 2847, which may be used for cement admixture, such as cupola slag, granulated ferrochrome slag, granulated blast furnace titanium slag.
