OBTAINING SUPERPLASTICIZERS BASED ON PYROLYSIS COARSE TAR PRODUCTS

Pyrolysis heavy distillate, naphthalene, indene, phthalic anhydride, superplasticizer.

Authors

The process of obtaining naphthalene, indene and phthalic anhydride based on the distillation of liquid and solid fractions of
heavy pyrolysis products has been implemented, the quantitative and qualitative composition of resin samples and the products of
processing of their fraction has been determined. Superplasticizers-additives for cement have also been created, their strength, the
average density of cement particles, the influence of the amount of superplasticizers and the duration of their operation on the
properties of the material have been studied.
