Research on the surface abrasion resistance performance of basalt fiber reinforced concrete

Abstract

The visual characterization of the surface erosion structure of concrete can serve as an initial analysis method for the overall abrasion resistance performance, providing a reference for the rapid formation of a preliminary understanding of the level of abrasion resistance performance. This research investigates the impact of erosion on the durability of coastal concrete. The "two-dimensional" and "three-dimensional" feature description methods are applied to study concrete damage and its mechanical properties. The findings indicate that increasing erosion cycles have a noticeable adverse effect on the specimen's surface, and higher water-cement ratios decrease strength while increasing quality loss. By categorizing the erosion cycle into three stages based on concrete surface damage, exposed aggregate area, and depth changes, it's observed that Basalt Fiber-Reinforced Concrete (BFRC) exhibit improved abrasion resistance and reduced quality loss during these stages. BFRC demonstrates its best abrasion resistance at a water-cement ratio of 0.3. The inclusion of basalt fibers significantly boosts concrete compressive strength with an enhancement ranging from 10.1% to 17.5% across various curing ages and water-cement ratios.
