Abstract
The fresh and mechanical properties as well as the durability of the polyvinyl alcohol (PVA) fiber-reinforced rubber mortar were evaluated in this study. The mini-slump test showed that the workability of the cement mortar was decreased with the both added rubber aggregates and PVA fibers. The mechanical strength was reduced in rubberized mortar compared with the plain cement mortar. The added PVA fiber with optimized content improved the compressive strength of the rubberized mortar. The ultrasonic wave velocity test showed that the dynamic modulus of the rubberized mortar was lower than that of plain mortar. In addition, the fiber reinforcement can enhance dynamic modulus (shown as the increased ultrasonic wave velocity) in the rubberized mortar mixtures. The drying shrinkage of the cement mortar was reduced by using the low content of the rubber aggregate as well as applying the PVA fiber reinforcement.
