“…One of the important components of polymeric concrete is dispersed filler. According to chemical nature the fillers are divided into mineral (chalk, talc, mica, microcalcite, asbestos, vermiculite, metal powders sand, fiberglass, various wastes of the metallurgical and energy industries) and organic (graphite, wood flour, soot, coke, starch, crushed foams waste and plastics) [5][6][7][8][9][10][11][12][13]. The main requirements for fillers are the ability to combine with the polymer or disperse in it with the formation of homogeneous compositions, good wettability by melts or solutions of polymers or oligomers, stability of properties during storage, processing and operation.…”
