A STUDY ON MECHANICAL PROPERTIES OF PVA FIBER REINFORCED SUPER-LIGHTWEIGHT MORTAR
Preview AbstractIn this study, not only bending strength of Super-lightweight mortar (SLM) but also resistance to impact load of it, with several types of PVA fibers of different lengths and diameters, were investigated. It was shown that, when the diameter of the fiber decreased and fiber-volume fraction increased, bending strength and resistance to the impact load were generally improved. However, the effect of the performance improvement of the SLM showed the tendency to become small in mix proportion that has too large total surface area of fiber.
