Abstract(s)
To date, glass fibre reinforced polymer (GFRP) waste recycling is very limited and
restricted by thermoset nature of binder matrix and lack of economically viable enduse
applications for the recyclates. In this study, efforts were made in order to recycle
grinded GFRP waste proceeding from pultrusion production scrap, into new and
sustainable composite materials. For this purpose, GFRP waste recyclates, a mix of
powdered and fibrous materials, were incorporated into polyester based mortars as
fine aggregate and filler replacements, at different load contents (between 4% up to
12% of total mass) and particle size distributions. Potential recycling solution was
assessed by mechanical behaviour of resultant GFRP waste modified polymer
mortars. Test results revealed that GFRP waste filled polymer mortars present
improved flexural and compressive behaviour over unmodified polyester based
mortars, thus indicating the feasibility of GFRP waste reuse in concrete-polymer
composites.
