“…Haikuan et al recently investigated the erosion resistance of normal concrete (NC) and recycled plastic concrete (RPC) in a solution of sodium sulfate at concentrations of 3%, 5%, and 7% [17]. According to the results, as the erosion concentration and time increase, the mass increase rate of RPC and NC also increases.…”

The mechanical properties of mortar containing Polyethylene Terephthalate (PET) as Strapping Band Fibers (SBF) replacing natural sand have been studied by many researchers. These studies indicate that when SBF is used as a substitute for sand in mortar, the characteristics in both the fresh and hardened states are altered. This experiment’s purpose is to valorize local materials, which are abundant in the region of Djelfa (Algeria), in cement mortar manufacturing and to discuss the influence of these materials on the mechanical and physical characteristics of the resulting mortar at the room, and at the high temperature. This study presents the results of an experimental investigation into the effects of high temperatures on the properties of dune sand mortar made with strapping band fibers. The method for formulating the mortar mixes was based on the progressive replacement of dune sand by PET fibers, with weight contents of 0%, 0.5%, 1%, 1.5%, 2%, and 2.5%. Several tests have been carried out to study the evolution of the different characteristics of mortar mixtures. The workability, bulk density, compressive and tensile strengths, and all samples were subjected to temperatures of ambient, 100 °C, 200 °C, and 400 °C. The results demonstrate that the inclusion of the recycled fibers and the preservation mode had remarkable effects on the characteristics of the mortar obtained.

The rapid increase in the number of electronic products worldwide, in terms of both variety and advanced technology, together with the decrease in costs, has led to the generation of a large amount of electronic waste (e-waste), which has significantly increased environmental pollution. This study was conducted to investigate the hypothesis that the adhesion of polymer binders and plastic origin e-waste will be more effective and stronger, and therefore have a positive effect on the permeability properties of polymer concrete and its behavior against aggressive solutions. For this purpose, quartz aggregates and gravel used as an aggregate in polymer concrete were replaced with 0%, 3%, 6%, 9%, 12% and 15% e-waste. In the study where unsaturated polyester resin was used as a binder, the changes in the permeability properties (capillary water absorption, rapid chloride permeability) of the e-waste polymer concrete and its behavior against aggressive solutions (acid and sulfate attacks) were evaluated after 7, 28 and 90 days. In addition, mechanical experiments were conducted and comparisons were made. After the control concrete, the highest compressive strengths were obtained from the polymer concrete specimens using 3% e-waste, measured as 59.05 MPa, 64.5 MPa and 73.05 MPa after 7, 28 and 90 days, respectively. The research showed that polymer concretes with capillary water absorption coefficient values close to zero after 90 days can be produced with using up to 9% e-waste. The use of e-waste as an aggregate in polymer concrete at 3%, 6% and 9% e-waste, in particular, produced concrete with a high resistance to acid and sulfate attacks. The hypothesis of the study was confirmed after extensive experiments. Graphical Abstract
