Influences of Fiber Content on Mechanical Properties of Geopolymer Reinforced by Polyester Fibers

Abstract:

As for the synthesis of polyester fibers based geopolymer, different fiber contents (0 %, 0.1 %, 0.2 %, 0.3 %, and 0.4 %) are investigated to obtain the optimum synthesis condition by flexural and compressive tests. X-ray diffraction analysis (XRD) and scanning electron microscope (SEM) are employed to explore the crystalline structure and microstructure of composites. Results show that the addition of 0.2 % fiber is considered as the most suitable proportion in polyester-geopolymers.
