Abstract
FIELD: building materials industry, method is used for production of pieces from lactic acid production wastes. SUBSTANCE: method of building pieces production provides for mixing of gypsum-bearing and fibrous components, moulding and drying of piece. To decrease cost of piece wit keeping its mechanical strength wastes of lactic acid production - sediment after fermentation and gypsum slime in initial state are mixed with wood chips or alike in ratio of 1 : 3 : 6 by mass in terms of dry substance, then mixture is moulded and dried under press. Mechanical strength of pieces during bending is 4.8 - 5.4 MPa. EFFECT: decreased production costs, preserved mechanical strength.
