Strength characteristics of polyethylene terephthalate fiber concrete
Abstract
Strength characteristics of polyethylene terephthalate fiber concrete
Incoming article date: 16.01.2022This article contains the results of a study of the strength characteristics of concrete with the addition of various amounts and shapes of recycled polyethylene terephthalate (PET) fibers. In general, the use of fiber in concrete from waste PET materials (obtained by mechanical grinding), rather than heat-treated, can increase the tensile strength. The compressive strength is reduced. Industrial flex is not recommended to be used as a fiber (additive) in concrete, as this leads to a decrease in strength characteristics. Increased tensile strength is provided through the use of specially prepared PET fiber. The conducted research proved the possibility of using PET fiber in concrete from waste PET materials (obtained by mechanical grinding) PET fiber is recommended for use in concrete structures to increase tensile strength.
