Cement-based composite material based on fiber reinforcement
The invention discloses a fiber-reinforced cement-based composite material and a preparation method thereof. The composite material comprises steel fibers, modified polyvinyl alcohol fibers, fly ash, cement, fine aggregate and a water reducing agent. By adding the steel fibers, the tensile strength and the crack resistance of the material are effectively improved through a three-dimensional network structure, and the overall mechanical property of the material is enhanced. After the modified polyvinyl alcohol fiber is subjected to heat treatment and surface treatment, the interface bonding force with a cement matrix is remarkably improved, so that the crack resistance and durability of the material are improved. According to the preparation method disclosed by the invention, by optimizing the component proportion and the preparation process, the uniformity and fluidity of the mixture are ensured, and the prepared composite material has excellent mechanical properties such as compression resistance, fracture resistance, tensile strength and the like, and can meet high requirements of modern construction engineering on material properties.
本发明公开了一种基于纤维增强的水泥基复合材料及其制备方法。该复合材料包括钢纤维、改性聚乙烯醇纤维、粉煤灰、水泥、细骨料及减水剂。钢纤维的添加通过三维网络结构有效提高材料的抗拉强度和抗裂性能，增强了材料的整体力学性能。改性聚乙烯醇纤维经过热处理和表面处理后，与水泥基体的界面结合力显著提升，从而提高了材料的抗裂性和耐久性。本发明的制备方法通过优化组分配比和制备工艺，确保了混合物的均匀性和流动性，制得的复合材料在抗压、抗折、抗拉等力学性能方面表现优异，能够满足现代建筑工程对材料性能的高要求。
