The main objective of the present research is to determine the feasibility of using polypropylene (PP) waste to produce eco-friendly gypsum-based composites. Four different replacement levels of plastic waste were selected for analysis - 2.5%, 5%, 7.5% and 10% by weight of gypsum. The first stage of the experimental campaign consisted of...

The influence of waste cellulose acetate (CA) fibres in the physico-mechanical (i.e. density, surface hardness - Shore C, flexural and compressive strength) and thermal properties (i.e. thermal conductivity coefficient) of gypsum-based composites was evaluated in this study. Furthermore, complementary stereomicroscopy and scanning electron...

In the present research, nylon fibres, sourced from end-of-life fishing nets, are used as substitute of commercially available counterparts to produce eco-friendly reinforced-gypsum composites. The influence of two nylon fibre lengths, PA6/I and PA6/II, on physico-mechanical performance (i.e. density, surface hardness-Shore C, flexural and...
