Characteristics of Fly Ash as a Composite Filler

The object of the study was composite materials using fly ash from Burshtyn and Kurakhiv TPPs as fillers and polymer dispersions Policril 590 and Latex 2012 as matrices. The relationship between the composition of the types of fly ash from Ukrainian thermal power plants and the peculiarities of the energy state of the dispersed filler particles surface as a factor of interaction with the binder in forming the polymer composite structure was determined. The effect of high concentration of fillers on the formation of the pore structure and indicators of physical and mechanical properties of composites was evaluated. The possibility of adjusting the composite properties in the following range was established: water absorption 4.2-12.7%, abrasion 0.02-0.06 g/cm2, residual strain 0.3-1.3, Young's modulus 0.6-49.1 MPa.
