Research Progress on Steel-Polypropylene Hybrid Fiber Reinforced Cement-Based Material

摘要: 随着现代土木工程对材料性能要求的不断提高，水泥基材料作为最常用的建筑材料之一，其性能优化显得尤为重要。钢–聚丙烯混杂纤维作为一种新型增强材料，被广泛应用于水泥基材料中，旨在提升其抗拉强度、抗裂性等关键性能。钢–聚丙烯混杂纤维在水泥基材料中展现出明显的混杂效应，这种混杂效应不仅增强了材料的抗拉性能，还改善了其抗冲击性能。钢–聚丙烯混杂纤维的加入能够显著提升水泥基材料的力学性能、耐久性和应用范围，同时符合环保和可持续发展的要求，是一种极具前景的新型增强材料。

Abstract: With the continuous improvement of material performance requirements in modern civil engineering, cement-based materials as one of the most commonly used building materials, its performance optimization is particularly important. As a new type of reinforcement material, steel-polypropylene hybrid fiber is widely used in cement-based materials to improve its key properties such as tensile strength and crack resistance. Steel-polypropylene hybrid fibers exhibit obvious hybrid effect in cement-based materials. This hybrid effect not only enhances the tensile properties of the material, but also improves its impact resistance. The addition of steel-polypropylene hybrid fiber can significantly improve the mechanical properties, durability and application range of cement-based materials, and meet the requirements of environmental protection and sustainable development, which is a promising new reinforcement material.
