Mix design process of polyester polymer mortars modified with recycled GFRP was...
Ribeiro, M. C. S.; Fiúza, António; Castro, Ana Cristina Meira; Silva, Francisco J. G.; Dinis, M. L.; Meixedo, João Paulo; Alvim, Mário RuiIn this study, the effect of incorporation of recycled glass fibre reinforced plastics (GFRP) waste materials, obtained by means of shredding and milling processes, on mechanical behaviour of polyester polymer mortars (PM) was assessed. For this purpose, different contents of GFRP recyclates, between 4% up to 12% in weight, were incorporated into polyester PM materials as sand aggregates and filler replacements...
PLSR Models for Mechanical Strengths of Concrete Composite Materials Reinforced...
Castro, Ana Cristina Meira; Ribeiro, M. C. S.; Meixedo, João Paulo; Silva, Francisco J. G.; Alvim, Mário Rui; Fiúza, António; Dinis, M. L.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 compo...
Mechanical behaviour analysis of polyester polymer mortars modified with recycl...
Ribeiro, M. C. S.; Meixedo, João Paulo; Fiúza, António; Dinis, M. L.; Castro, Ana Cristina Meira; Silva, Francisco J. G.; Costa, C.; Ferreira, F.In this study the effect of incorporation of recycled glass-fibre reinforced polymer (GFRP) waste materials, obtained by means of milling processes, on mechanical behaviour of polyester polymer mortars was assessed. For this purpose, different contents of recycled GFRP waste powder and fibres, with distinct size gradings, were incorporated into polyester based mortars as sand aggregates and filler replacements....
Reusability assessment of thermoset polymeric composite wastes as reinforcement...
Ribeiro, M. C. S.; Dinis, M. L.; Fiúza, António; Castro, Ana Cristina Meira; Silva, Francisco J. G.; Meixedo, João Paulo; Costa, C.; Ferreira, F.The development and applications of thermoset polymeric composites, namely fiber reinforced polymers (FRP), have shifted in the last decades more and more into the mass market [1]. Production and consume have increased tremendously mainly for the construction, transportation and automobile sectors [2, 3]. Although the many successful uses of thermoset composite materials, recycling process of byproducts and end...
A case study on the improvement of eco-efficiency ratios: application to a comp...
Castro, Ana Cristina Meira; Ribeiro, M. C. S.; Silva, Francisco J. G.; Alvim, Mário Rui; Costa, C.; Fiúza, António; Dinis, M. L.; Meixedo, João PauloThe World Business Council for Sustainable Development (WBCSD) defines Eco-Efficiency as follows: ‘Eco- Efficiency is achieved by the delivery of competitively priced-goods and services that satisfy human needs and bring quality of life, while progressively reducing ecological impacts and resource intensity throughout the life-cycle to a level at least in line with the earth’s estimated carrying capacity’. Eco-...
Experimental study on polyester based concretes filled with glass fibre reinfor...
Castro, Ana Cristina Meira; Ribeiro, M. C. S.; Dinis, M. L.; Fiúza, António; Silva, Francisco J. G.; Meixedo, João Paulo; Alvim, Mário RuiThe development and applications of thermoset polymeric composites, namely fibre reinforced plastics (FRP), have shifted in the last decades more and more into the mass market [1]. Despite of all advantages associated to FRP based products, the increasing production and consume also lead to an increasing amount of FRP wastes, either end-of-lifecycle products, or scrap and by-products generated by the manufactur...
