“…Consequently, mortar composites modified with WPET can be advantageous to special applications, where the main request is not for mechanical properties, such as in the production of noise barriers and special concrete blocks for light concrete walls [15]. Ge et al [62] have elaborated a new type of mortar made with recycled clay brick (CB) and post-consumer polyethylene terephthalate (PET); they have concluded that the PET mortar had low water absorption of 0.87% and high resistance to sulfate attack and chloride ion penetration. Furthermore, these composites are often used as low-cost materials for preventing chemical attacks or repairing various reinforced concrete structures damaged by chloride-induced corrosion [63]; it is also used for restoring deteriorated mortar jointing and repairing mortar in historic buildings and walls damaged by chemical sulfate attacks.…”

Plastic industry produces large amounts of waste polyethylene terephthalate (WPET), what causes environmental problems. An investigation was carried out on the effect of sulfate attack on the durability of composites produced with WPET. An attempt was also made to determine the thermal coefficients as well as the dynamic elastic moduli. Experiments were accomplished on limestone sand and cement mortars where the blended Portland cement was partially replaced by various volume fractions of WPET particles. The test solutions used to supply the sulfate ions and cations were 5% sodium sulfate solution and 5% magnesium sulfate solution. Tap water was used as the reference solution. Mass changes, compressive and flexion strengths measured on specimens were used to assess the changes in the mechanical properties of composites exposed to sulfate attack at different times. X-ray diffraction, FT-IR spectroscopy, scanning electron microscope (SEM/EDS) and differential scanning calorimetry were used to evaluate the microstructural nature of the sulfate attack. The test results showed that the presence of WPET had a beneficial effect in the control of the strength loss due to sodium and magnesium sulfate attacks and gave better insulation properties. This study insures that reusing TWPET particles as cement substitutes in mortar gives a good approach to sulfate durability, insulation, mechanical properties and solves some of the solid waste problems posed by plastics. Therefore, WPET-mortar composites are often presented as the materials of the future because of their potential for innovation and the advantages they offer. In fact, using WPETs as cement substitutes reduces the energy consumption. These composites address problems related to environmental pollution by CO2 emissions, and are used to repair various reinforced concrete structures.

“…The hardness test is typically applied to 20 samples, ten of which are made from PET with bitumen addition and the others from DPET. The hardness result is generally shown in Figure (8) for the modification of bitumen within PET. When compared to bitumen without any addition, the best result was obtained with the addition of 40% PET, which is generally equal to 70 HRC.…”

“…One of the most significant and popular waterproof materials is polyethylene terephthalate (PET), which has a high performance to price ratio and exceptional qualities like high durability, superior mechanical and electrical capabilities, and low production costs. Because of this, it is frequently used in packaging, fabrics, and other things [8][9][10] [11] . Plastics are another material that is frequently used in brick construction in addition to the components described above.…”

In order to create environmentally friendly products, this article focuses on reducing plastic waste by recycling polyethylene terephalate (PET) bottles (Green materials). Depolymerized polyethylene terephthalate (DPET) is created by combining PET with ethylene glycol and magnesium oxide (MgO) at a moderate temperature until the mixture reaches 179 oC (ethylene glycol's boiling point) for 40 to 50 minutes. This process first breaks down the polymer into a monomer. Second, bitumen is combined with plastic (either PET or DPET) to create modified bitumen (MB), then modified bitumen is mixed with sand, silica and gravel in order to produce friendly and sustainable construction materials . Bricks have been produced from mixing the modified bitumen with percentage (10-20)% ,sand in percentage (50-60 ) % and gravel in percentage (30)%. The characterization was carried out for the bricks in two steps : The first was to examine the modified bitumen to determine the best ratio that could be used in the mixture. The hardness test showed the best ratio of modified bitumen in percentages (60% of bitumen and 40% of PET or DPET) percentage is due to the formation of a functional group between bitumen and plastic which has appeared with FTIR characterization . Secondly, the compressibility of the mixture was fully examined and the results showed the best compressive strength in 20% of modified bitumen with PET and 18% of modified bitumen with DPET. The compressive strength value is 7MPA and 6.9 MPA respectively. Finally , the recent results are compared with the previous research, and the results showed a reduction in the cost as a result of the use of waste materials and an increase in compression value.

“…Se ha utilizado como agregado, como aglutinante del cemento y sustituir como refuerzo de fibras (Mahdi et al 2010). Usar fibras de PET reciclado en concreto ayuda a mejorar su ductilidad, reduciendo así el agrietamiento debido a la contracción plástica, pero este método solo recicla una pequeña cantidad de residuos de PET (Ge et al 2015). Kim et al (2010) presenta un método para reciclar botellas de PET desechadas, se utilizan fibras cortadas hechas de PET reciclado dentro del concreto estructural.…”

RESUMENHoy en día enfrentamos un problema sobre la protección ambiental, el estilo de vida moderno junto con las nuevas tecnologías causó más producciones de materiales de desecho para los cuales existe el problema de eliminación. Uno de ellos son las botellas PET que debe desecharse o reciclarse adecuadamente para mantener limpia el medio ambiente, ya que se clasifican como materiales no biodegradables. Para abordar este problema, se realizó un estudio experimental del efecto del reciclado de las fibras de botella PET en la resistencia del concreto normal, fibras obtenidas mediante un reciclado mecánico. Se elaboró una serie de mezclas de concreto con adición de fibras PET de 0 % a 8 % estimada respecto al peso del cemento. Los concretos resultantes se compararon con el concreto normal (0 % de PET). Se analizó la resistencia a la compresión y resistencia a la flexión del concreto respectivamente. Los resultados indican que para concreto con 2 % de PET alcanza su máxima resistencia a la compresión logrando un incremento de 2,6 % y el concreto con 4 % de PET disminuye en 6,3 %, no obstante, alcanza una resistencia superior a 210 kg/cm2. La resistencia a la flexión para concreto con 4 % de fibras de PET aumenta a 24 %. Por lo tanto, hasta 4 % de fibras de PET es posible adicionar para lograr una resistencia adecuada del concreto, método muy útil para resolver algunos problemas de desechos de PET en el medio ambiente.Palabras Clave: Fibras de las botellas PET, medio ambiente, reciclado, resistencia a la compresión, resistencia a la flexión.
