Compressive Strength of Woven and Strand of Recycled Polyethylene Terephthalate (PET) Reinforced Concrete

Abstract

Woven fiber reinforced concrete is a material, which contains various quantities of polymer materials in composition, in addition to the conventional components of an ordinary concrete (mineral binder - cement, aggregates, water and additives). The present work refers to the concrete in which the reinforcement is made of polymeric materials (polyethylene terephthalate), originated from the recycling programs of PET-type packaging. The experimental program was aimed at constructing some samples of woven fiber reinforced concrete from recycled material coming from PET packaging wastes, their testing to the compression demands and the comparison of results with the characteristics of the standardized samples of concrete (class C30/37). Based on a sufficient number of determinations, certain correlations can be established between the compressive strength of the concrete at 28 days depending on the dosage of components (aggregate, binder, and reinforcement), water / cement ratio, reinforcement volume, etc., essential parameters from a compositional point of view. These correlations, customized by cement type and strength class, are very important to determine - with approximation - to what dosage of components (aggregate, binder, reinforcement) the respective level of compressive strength of concrete is obtained.

Reinforcing concrete with recycled plastic wastes

“…To continue to be competitive, concrete has improved a number of properties, resulting in new types of concrete, such as: high-strength concrete, high-performance concrete, dispersed fibre concrete, reactive powder concrete, polymeric concrete, heavy concrete, apparent concrete, etc. [4,[16][17][18] Concrete is made from natural aggregates, cement and water, compounds that make it a cheap and easy material to produce anywhere. Typically, ordinary concrete contains about 12% cement, 8% water and 80% aggregates (Figure 2, Table 1) [4,[16][17][18].…”

The new concretes use different types of additions in the composition (Figure 3).…”

“…This research aims to contribute to the depollution of the environment by designing a new ecological and innovative concrete that incorporates as much recycled waste as possible from the PET waste category [16][17][18]. Research aims to use waste stocks, for which the current recycling possibilities are limited.…”

“…It can be turned into synthetic fibres or foil. This category includes colourless or coloured PET vials for water, beer, alcoholic beverages, juices, vegetable oil, and other plastic containers [16][17][18].…”

Study on Compressive Properties of Recycling PETs and CANs for Designing a Smart Waste Management Compactor

“…After a set of tests, most of the functionalities and performance were confirmed but it was proved that for continuing design optimization of mechanical subsystem with the compressing active parts and for software subsystem optimization, a deeper study on Compressive Properties of pets and cans is needed [5].…”
