FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy. Clinker has the following chemical composition, wt %: Al2O3 30-85, CaO 3-45, MgO 9-45, in a mineralogical composition, wt %: phase Q (Ca20Al32-2xMgxSixO68, where 2.5≤x≤3.5) 15-65 and phase MgAl2O4 5-40. Clinker has open porosity measured by a test for determination of open porosity by submersion into water according to modified standard NF B 40-312, which is equal to 4-60%.
EFFECT: reduction by clinker of dust formation.
