FIELD: production of claydite. SUBSTANCE: into clay raw materials additives are added, then granules are formed, dried, roasted and cooled. Herbicides from group of symmetric triazine or preparation on their base are used as said additives, their quantity being 1-2 mass %. Additionally alkali-containing additive (its quantity being 0.5-2 mass %) or polishing slime (its quantity being 0.5-2 mass %) are used. Mentioned above roasting is carried out at 1070-1150 C. Density thus prepared claydite is 360-380 kg/m3, its compressing strength being 2.05-2.15 MPa. EFFECT: improves efficiency of the method. 1 tbl
