This article presents research results relating to the potential for waste utilization in the form of polymer optical fiber (POF) scraps. This material is difficult to recycle due to its diverse construction. Three different volumes of POF were used in concrete in these tests: 1%, 2%, and 3%. The experimental studies investigated the basic properties of the concrete, the elastic and dynamic moduli, as well as deformation and deflection of reinforced beams. The microstructures, including the interfacial transition zones (ITZs), were recorded and analyzed using a scanning electron microscope. It was observed that 180 freezing–thawing cycles reduced the concrete frost resistance containing 3% POFs by half compared to the control concrete. The resistance to salt crystallization of this concrete decreased by about 55%. POFs have significant effects on the splitting tensile and flexural strengths compared to the compressive strength. The control beams were destroyed during the four-point static bending tests at half the force applied to the beams that were reinforced with POFs.

“…Post-consumer polymeric waste is a pollution source which seriously damages the environment, generally trending to be aggravated if efficient management and recycling policies are not adopted [1][2][3]. In this context, waste from elastomeric products used in the automobile and footwear industries has been drawn attention, since the vast majority are vulcanized, therefore lasting decades to be decomposed [4,5].…”

Reusing rubber waste from footwear industry emerges as great practise in order to reduce environmental damage on natural ecosystems. Based on this target, the present work aimed to apply the response surface methodology (RSM) to polystyrene/styrene-butadiene PS/SBRr blends compatibilized with styrene-ethylene-butylene-styrene (SEBS). A mixture planning was applied to PS/SBRr/SEBS blends in order to investigate mechanical and thermomechanical behaviors as response variables. Scanning electron microscopy (SEM) was used to evaluate the morphology of investigated blends, which were melt extruded in a corrotational twin screw extruder and specimens were injection moulded. High impact strength, toughness, elongation at break and thermal deflection temperature (HDT) were achieved at SEBS rich region (∼10%). At PS rich region, tensile strength, Shore D hardness and Vicat softening temperature (VST) were more expressive. Related to morphological character, blends with 10% SEBS presented the highest interfacial adhesion, with high level of plastic deformation. Gathered results show that depending on the composition, properties significantly change, being RSM a proper tool to preview trends on mechanical and thermomechanical properties. In general, PS/SBRr/SEBS blends may be properly used as packaging and building applications.Danilo Diniz Siqueira https:/ /orcid.org/0000-0002-3533-513X Renate Maria Ramos Wellen https://orcid.org/0000-0002-3565-7366
