Resumo
The article describes the results of a study to determine the simultaneous effect of polyethy-
lene terephthalate waste (PET) and polyethylene (PE) on the strength characteristics and bulk density
of epoxy mortars. In these mortars, 9 wt.% of the polymer binder was replaced by glycolysate which
was made from PET waste and propylene glycol. Additionally, 0–10 vol.% of the aggregate was
substituted with PE agglomerate made from plastic bags waste, respectively. The modification of
the composition of epoxy mortar has a special environmental and economic aspect. It also allows to
protect natural sources of the aggregate, while reducing the amount of waste and reducing problems
arising from the need to store them. The resulting composite has very good strength properties.
With the substitution of 9 wt.% of resin and 5 vol.% of sand, a flexural strength of 35.7 MPa and
a compressive strength of 101.1 MPa was obtained. The results of the microstructure study of the
obtained mortars constitute a significant part of the paper.
