FIELD: construction.
SUBSTANCE: method of production of composite carbonised products including moulding of products from moulding material produced on the basis of slaked calcium or dolomite lime and filler in the form of wastes from production and processing of limestones with fraction of up to 5 mm, moulding is carried out at pressure of 50-150 kgf/cm2, carbonisation of products with carbonic acid gas with flow value of 0.2 l/cm2 at least for 3-6 hours. The method provides for production of artificial material with strength of 9-20 MPa at average density of 1350-1700 kg/m3, softening coefficient of which amounts to 0.77-0.88.
EFFECT: increased strength.
