Abstract

In order to improve the performance of hydraulic structure flow surface against high-speed sand-containing water flow impact and wear, an orthogonal test was designed to study the effects of three fiber dosage levels of polyvinyl alcohol fiber, polypropylene fiber and steel fiber on the compressive properties, splitting properties and impact and wear resistance of C35 impact and wear resistant concrete. Based on the concept of value engineering, the optimal fiber dosage was determined within the test range. The results show that adding the above three kinds of fibers to concrete will slightly reduce the compressive strength of concrete, but can significantly improve the splitting strength and impact and wear resistance of concrete. Among them, the PVA fiber dosage level has a significant effect on the splitting strength of concrete, and the PVA fiber and PP fiber dosage levels have a significant effect on the impact and wear resistance of concrete. Considering the performance and cost of concrete comprehensively, the impact and wear resistant concrete mix ratio of 1kg/m3PVA fiber and 1kg/m3PP fiber can achieve the best production efficiency.
