Claims (3)

1. Способ определения дисперсности формованного торфа, включающий определение величины предельного напряжения сдвига, отличающийся тем, что предельное напряжение сдвига определяют на образце формованного торфа целостной структуры с помощью пенетрометра с последующим определением из того же образца влагосодержания и расчетом дисперсности.1. A method for determining the dispersion of molded peat, including determining the value of the ultimate shear stress, characterized in that the ultimate shear stress is determined on a sample of the molded peat of an integral structure using a penetrometer followed by determining the moisture content from the same sample and calculating the dispersity. 2. Способ по п. 1, отличающийся тем, что для верхового торфа расчетная формула
So=100(9-2lnθ-0,1W)±5,
где So - условная удельная поверхность, м2/кг;
θ - предельное напряжение сдвига, кПа;
W - влагосодержание, кг/кг.2. The method according to p. 1, characterized in that for top peat calculation formula
