“…The amount of polymer binder used was determined according to the filling. The filling with secondary raw material was chosen based on previous research, where 25 wt.% filling was used [32], to test the waste parameters and viscosity of the polymer resin. The proposed formulations were tested in fresh and polymerised states.…”

In this study, the suitability of waste from glass fibre production as a secondary filler for a polymeric durable hydrophobic coating, based on an innovative polyurethane organic–mineral base, was experimentally verified. The main aim of this work was to develop a basic formulation for a polymeric hydrophobic coating designed primarily for usage in aggressive environments. For this purpose, a total of four formulations were tested with different weight percentages of waste glass fibre, i.e., from 30 to 60%. The basic properties in the fresh state, such as the coating workability and kinematic and dynamic viscosity, were verified, and an application test was performed. The formulations were also verified after the polymerisation of the coating. Adhesion on a concrete substrate and the tensile properties and hardness of the coating were tested. Chemical resistance to liquid aggressive media and the microstructure of the coating after exposure to SO2 were also tested, as these are critical properties. All the formulations showed better workability than the reference coating without a filler, and the formulation with the highest filling (60%) appeared to be optimal. The maximum adhesion on the concrete substrate (11.9 MPa) and tensile strength (21.6 MPa) were recorded for the formulation with 60% waste fibreglass. It can be concluded that with an increase in the waste glass content, there was a significant improvement in the properties of the coatings. Additionally, the waste fibreglass did not have a significant negative impact on chemical resistance.

“…The elastomers mass of nitrile-butadiene rubber NBR, epoxy elastomers and polyurethane elastomers decreased substantially and complete degradation occurred after immersed in chemical solutions with 1 month. [50][51] Therefore, compared with (NBR), epoxy elastomers and polyurethane elastomers, PU-15UPy exhibited excellent chemical resistance performance.…”

Self‐healing polyurethane elastomers allow increasing the life cycle, adapting to the circular economy, thus reducing the generation of waste. In this work, ureido‐4[1H]‐pyrimidinone (UPy) compounds was used to construct on supramolecular polymer. The self‐healing polyurethane elastomers were successfully prepared by supramolecular polymer based on UPy via a simple blending way. The self‐healing performance of the polyurethane elastomers with UPy were investigated by the scratch test and the cut‐off test, respectively. The scratch of the self‐healing polyurethane elastomer (PU‐15UPy) was totally healed in 1 h at 35°C. The tensile strength and the elongation at break of PU‐15UPy were 0.81 MPa and 563.8%. After the cut‐off test, the healing efficiencies of tensile strength were 63.8% (0.51 MPa) and 85.2% (0.69 MPa) after healing for 10 h at 35 and 80°C, respectively. The healing efficiency of tensile strength reached the value of 90.1% (0.73 MPa) after healing for 24 h at 80°C. The chemical resistance of the self‐healing polyurethane elastomers was tested by immersion in water, NaCl solution (3%), HCl solution (5%), NaOH solution (5%), and diesel, respectively. The mass loss of self‐healing polyurethane elastomers were all less than 2% after immersed in these solutions for 1 month, indicating the excellent chemical resistance performance of PU‐15UPy.

“…It was found that the addition of glass powder in a proportion of 19.4% to the epoxy resin is the most beneficial and increases the peel strength of the mortar. Epoxy coatings modified with glass waste were also obtained by Jana Hodná et al [20]. Thanks to the use of waste glass as filler, the tensile strength and hardness were improved, and its addition did not negatively affect chemical resistance or adhesion to the substrate.…”

The ecological construction of the future aims to reduce the amount of waste and minimize energy consumption related to the production and transport of building materials. One way to stop the destructive effects of the excessive exploitation of natural deposits is to implement extensive activities aimed at reusing, preferably multiple times, waste materials. This article describes the results of testing polyester mortars based on the developed experimental plan. It assumed the use of waste glass cullet as a sand replacement in the amount of 0–100% by mass and a variable resin/aggregate ratio in the range of 0.14–0.36. The use of a two-factor central composition plan allowed us to limit the number of research samples and at the same time obtain the necessary scientific information regarding the obtained mortars. Standard tests for flexural and compressive strength and bulk density were performed on rectangular hardened samples. Additionally, the change in the mass of the samples immersed in water was monitored for a period of 165 days. The analysis of the strength test results allows us to conclude that, with appropriately selected proportions of resin-glass waste, composites with a flexural strength of 30 MPa and a compressive strength of 91.4 MPa can be obtained. Including waste in a mortar allows elements with low water absorption to be obtained. At the same time, their production is about 2.5 times cheaper than their epoxy counterparts. The test results were compared with those obtained for epoxy-based mortars and with reference to the requirements set by the manufacturers of prefabricated polymer concrete elements intended for construction applications.
