METHOD FOR OBTAINING FSSC (FIBRE-SLUDGE-SULFUR CONCRETE)

摘要

The invention relates to the building materials industry - for road construction, in the manufacture of concrete and reinforced concrete products or structures, and also mortars. The technical result is the production of a new road surface, as well as construction concrete and reinforced concrete products or structures resistant to external mechanical and thermal impacts, aggressive environments, with increased crack resistance, hydrophobicity and production safety, during which no harmful substances (hydrogen sulphide and sulfurous anhydride) are emitted. The object of the invention is to develop a method for obtaining of FSSC having high resistance to corrosive environments, low and high temperatures, dynamic overloads, and the use in production of a sulfur-concrete mixture of industrial environmental waste for their utilization and elimination of occupational hazards. The said goal is achieved by a certain sequence, consisting of two stages: stage I - production of sulfur binder - modified sulfur (sulfur copolymer) produced from the lump sulfur acid by means of the vortex bed apparatus (VBA) with maximum capacity of 15-35 m/h; stage II - production of FSSC - at a mobile asphalt plant, sulfur binder and organic additives with inert fillers are mixed and heated (temperature no higher than 120°C, for 20-30 minutes): drilling sludge, basalt fiber and construction sand, resulting in melting of the modified sulfur (sulfur copolymer) in the environment of organic additives and inert fillers, for disperse reinforcement and composite.
