Analysis Of Strength and Durability Characteristics of Geopolymer Concrete using Pet Bottle Fibers

The rise in demand for green building materials has led to the creation of a new type of concrete, known as geopolymer concrete, to replace conventional concrete. This study is focused on analyzing the strength and durability of geopolymer concrete by incorporating recycled PET bottle fibers. For this research, fly ash is used as a main binder, activated by alkaline solutions such as sodium hydroxide (NaOH) and sodium silicate (Na₂SiO₃), replacing ordinary Portland cement. These alkaline solutions are used to prevent carbon emissions. PET bottle fibers, derived from waste plastic bottles, are used in this research to improve the mechanical properties of concrete.
