Mechanical Properties of Polymer Modified High Volume Fly ash Concrete (PMHVFAC) Using Hybrid Textile Fibers

Abstract

This paper presents the behavior of polymer modified high volume fly ash concrete (PMHVFAC) using hybrid textile fibers under compressive strength, tensile strength, flexural strength and shear strength. According to the geometrical parameters of textile fibers, the textile fibers can be effective in delaying propagation of micro cracks or macro cracks. In the present paper, the high volume fly ash concrete (HVFAC) is mixed with several single (mono) textile fibers and two-fiber (hybrid) textile fibers. The specimens are cured in water for 28 and 90 days in order to enhance PMHVFAC's mechanical properties. Microstructures of the composites were analyzed by using scanning electron microscope. The findings indicate that it is possible to improve PMHVFAC's mechanical properties in every way by adding hybrid textile fibers. PMHVFAC produced with hybrid textile fibers exhibit higher strength characteristics as compared to PMHVFAC produced with mono textile fibers. Additionally, in comparison to other hybrid fiber combinations, it is evident that PMHVFAC produced with the (CF+PPF) hybrid textile fiber combination has greater strength capabilities.
