“…And, finally, the third direction seems to be the most promising: the production and subsequent use of hydrophobically-modifying additives (HMA). Characteristics of the porous structure of peat particles [9][10][11] make it possible to saturate the system with various types of traditional hydrophobic agents: bitumen [12], oleic acid, organosilicon compounds, etc. [13,14].…”

The method of hydrophobic modification of dispersed materials is based on the extraction of bituminous components of peat and applying them to a treated surface. The industrial implementation of this method is possible in the following main directions. First, it is the thermochemical treatment in a reactor of the entire material volume by hydrophobic components of peat with a low concentration. Second, it is the obtaining of concentrated hydrophobically-modifying compositions and their use in the production technology of various types of powdered dispersed materials. Positive results were obtained with organo-mineral hydrophobically- modifying concentrates based on peat with clinker, kaolin, chalk, lime, vermiculite. Third, it is the use of the sorption properties of the porous structure of peat to saturate it with additional hydrophobic components: bitumen, oleic acid, organosilicon compounds, etc. The main advantage of the obtained composite hydrophobic modifiers is quality (accurate) dosing. There are promising directions of the use of hydrophobically-modifying additives in the construction industry, chemical industry and to ensure fire safety. A block diagram of the technological process of complex peat processing to produce hydrophobic and hydrophilic powders is proposed. Additional processing of production wastes allows for the production of a stabilizing additive for asphalt concrete.
