Abstract | 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) ... 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 microscopy analysis were carried out. Lighter composites were obtained with ensuing incorporation of waste CA fibres. In comparison to the control material, an improvement on flexural and compressive strength, up to ∼9 % and ∼1 %, respectively was observed. Moreover, a slight declining trend in thermal conductivity was found with increasing replacement level (up to ∼16 % decrease). |
