摘要
由于水工建筑物持续暴露在各种类型的水中，磨损是水工建筑物面临的主要问题。因此，这些结构很容易损坏，需要大量维护。在寻找新技术来提高水工建筑物中混凝土的抗侵蚀能力方面，有很大的需求。这项工作提出了两种不同类型的混凝土在阻力方面的性能对比分析，即高性能纤维增强混凝土(HPFRC)[钢纤维(30毫米和50毫米)和聚丙烯纤维(19毫米)]和高性能混凝土(HPC)。对其耐磨性和水磨侵蚀性能进行了对比研究。采用WMP ECLIPSE方法和ASTM C 1138方法进行分析。结果表明，根据水泥、纤维、混凝土的种类和添加硅粉等改性剂，磨损率可降低18%。
Abrasion is a major problem in hydraulic structures as they are continuously exposed to various types of water. Henceforth, these structures are susceptible to damage and require heavy maintenance. There is a significant demand in finding new techniques for improving the resistance towards the erosion of the concrete used in the construction of hydraulic structures. This work put forth a comparative analysis of the performance of two different types of concretes towards resistance namely, high-performance fiber reinforced concrete (HPFRC) [steel fibers (30 mm and 50 mm) and polypropylene fibers (19 mm)] and high-performance concrete (HPC). A comparative study was carried out based on their resistance towards wearing and hydro-abrasion erosion. The analyses were conducted using the WMP ECLIPSE method and ASTM C 1138 method. The results indicated that the rate of abrasion could be diminished by 18% based on the types of cement, fibers, concrete and modifications like the addition of silica fume.
