Abstract(s)
In this study, a new waste management solution for thermoset glass fibre reinforced
polymer (GFRP) based products was assessed. Mechanical recycling approach, with
reduction of GFRP waste to powdered and fibrous materials was applied, and the
prospective added-value of obtained recyclates was experimentally investigated as raw
material for polyester based mortars. Different GFRP waste admixed mortar formulations
were analyzed varying the content, between 4% up to 12% in weight, of GFRP powder
and fibre mix waste. The effect of incorporation of a silane coupling agent was also
assessed. Design of experiments and data treatment was accomplished through
implementation of full factorial design and analysis of variance ANOVA. Added value of
potential recycling solution was assessed by means of flexural and compressive loading
capacity of GFRP waste admixed mortars with regard to unmodified polymer mortars.
The key findings of this study showed a viable technological option for improving the
quality of polyester based mortars and highlight a potential cost-effective waste
management solution for thermoset composite materials in the production of sustainable
concrete-polymer based products.
