FIELD: manufacture of building materials.
SUBSTANCE: method provided by invention is characterized by jointly grinding two clinkers, dividing thus resulting cement into two streams, jointly mixing cement from one and the other streams with sand and additive, and determining parameter En, i.e. exergy of resulting mix equal to sum of amount-exergy products for each of mix components. The latter parameter is assumed as governed and exergy of cement streams is assumed as governing. When calculated exergy of mix goes below from its specified value, amount of cement in stream with higher exergy is increased and, when calculated exergy exceeds its specified value, amount of sand is increased.
EFFECT: facilitated on-line process control.
