Erosion test with high-speed water jet applied on surface of concrete treated with solution of modified lithium silicates

Abstract

The paper focuses on the erosion resistance test based on surface treatment by a high-speed water jet applied on concrete. A reference concrete sample and concrete samples with three types of solution of modified lithium silicates applied on the concrete surface were tested under various erosion conditions. Two different jet impact angles (45° and 90°) were investigated. A significant difference in the erosion rate in the surface layers was observed comparing the untreated concrete and the concrete treated by various solutions of modified lithium silicates, but only in the initial phase of erosion.
