Abstract(s)
In this paper, we present two Partial Least Squares Regression
(PLSR) models for compressive and flexural strength responses of a
concrete composite material reinforced with pultrusion wastes. The
main objective is to characterize this cost-effective waste
management solution for glass fiber reinforced polymer (GFRP)
pultrusion wastes and end-of-life products that will lead, thereby, to
a more sustainable composite materials industry. The experiments
took into account formulations with the incorporation of three
different weight contents of GFRP waste materials into polyester
based mortars, as sand aggregate and filler replacements, two waste
particle size grades and the incorporation of silane adhesion
promoter into the polyester resin matrix in order to improve binder
aggregates interfaces. The regression models were achieved for these
data and two latent variables were identified as suitable, with a 95%
confidence level. This technological option, for improving the
quality of GFRP filled polymer mortars, is viable thus opening a
door to selective recycling of GFRP waste and its use in the
production of concrete-polymer based products. However, further
and complementary studies will be necessary to confirm the
technical and economic viability of the process.
