To reveal the law of influence of hybrid fibers on the mechanical properties and deformation behavior of strain hardening cementitious composites (SHCC), the tensile and compressive properties of basalt-polyvinyl alcohol(PVA) fiber strain hardening cementitious composites (SHCC) were investigated at a constant fiber content of 2% (in volume fraction), different content ratios of basalt fiber and PVA fiber (i.e., 3∶1, 1∶1 and 1∶3), and different ratios of fly ash to cement (FA/C) (i.e., 1.2, 1.5 and 2.0). The direct tensile and compressive strengths of hybrid fiber SHCC with different fly ash contents were analyzed. The horizontal and vertical strain evolution and crack development of the sample during compression were discussed via digital image correlation (DIC). The results show that the compressive strength of the mixed fiber specimens is greater than that of the single fiber specimens, indicating that the hybrid fiber can effectively improve the compressive strength. At FA/C ratios of 1.2 and 1.5, the optical fiber type is B0.5P1.5 (i.e., the volume fraction of basalt fiber is 0.5% and PVA fiber is 1.5%). At a FA/C ratio of 2.0, the optical fiber type is B1P1. The optical fiber type is different for different fly ash admixtures, indicating that the fly ash admixture affects the optical fiber type. In the hybrid fiber specimens, basalt fibers mainly play a role in improving the strength, but it is not suitable for the ductility of the material. In contrast, incorporating PVA fibers can effectively enhance the material's ductility, the addition of hybrid fibers can enhance the mechanical properties. The DIC can effectively characterize the strain evolution and crack formation and propagation process of the material, thus providing an effective method for investigating the material damage and crack evolution in the loading process.

为揭示混掺纤维对应变硬化水泥基复合材料力学性能和变形行为的影响规律,研究了玄武岩-聚乙烯醇(PVA)纤维应变硬化水泥基复合材料的抗拉、抗压性能及压应变演化特征。设计了纤维掺量为材料体积分数的2%,玄武岩纤维和PVA纤维掺量比分别为3∶1、1∶1和1∶3,同时控制粉煤灰与水泥掺量的比值(FA/C)分别为1.2、1.5和2.0。对不同粉煤灰掺量的混掺纤维应变硬化水泥基复合材料进行直接拉伸和抗压实验,利用数字图像相关技术(DIC)对试样压缩过程中的水平、竖向应变演化及裂缝开展进行了分析。结果表明:混掺纤维试样的抗压强度要明显高于单掺纤维试样的抗压强度,表明混掺纤维能够有效改善材料的抗压强度;在FA/C(粉煤灰与水泥掺量的比值)为1.2和1.5时,最佳纤维类型为B0.5P1.5(玄武岩纤维体积分数0.5%,PVA纤维体积分数1.5%),FA/C为2.0时,最佳纤维类型为B1P1,即粉煤灰掺量不同,材料最佳纤维类型也不同,表明粉煤灰掺量影响最佳纤维类型;在混掺纤维试样中,玄武岩纤维主要起提高材料强度的作用,但其对材料的延性发展不利,而PVA纤维的掺入能够有效改善材料的延性,混掺纤维使材料的力学性能更加优越;同时DIC技术可以有效表征材料应变演化及裂缝形成和扩展过程,为研究受力过程中材料损伤和裂缝演化提供一种有效手段。

为揭示混掺纤维对应变硬化水泥基复合材料力学性能和变形行为的影响规律,研究了玄武岩-聚乙烯醇(PVA)纤维应变硬化水泥基复合材料的抗拉、抗压性能及压应变演化特征。设计了纤维掺量为材料体积分数的2%,玄武岩纤维和PVA纤维掺量比分别为3∶1、1∶1和1∶3,同时控制粉煤灰与水泥掺量的比值(FA/C)分别为1.2、1.5和2.0。对不同粉煤灰掺量的混掺纤维应变硬化水泥基复合材料进行直接拉伸和抗压实验,利用数字图像相关技术(DIC)对试样压缩过程中的水平、竖向应变演化及裂缝开展进行了分析。结果表明:混掺纤维试样的抗压强度要明显高于单掺纤维试样的抗压强度,表明混掺纤维能够有效改善材料的抗压强度;在FA/C(粉煤灰与水泥掺量的比值)为1.2和1.5时,最佳纤维类型为B0.5P1.5(玄武岩纤维体积分数0.5%,PVA纤维体积分数1.5%),FA/C为2.0时,最佳纤维类型为B1P1,即粉煤灰掺量不同,材料最佳纤维类型也不同,表明粉煤灰掺量影响最佳纤维类型;在混掺纤维试样中,玄武岩纤维主要起提高材料强度的作用,但其对材料的延性发展不利,而PVA纤维的掺入能够有效改善材料的延性,混掺纤维使材料的力学性能更加优越;同时DIC技术可以有效表征材料应变演化及裂缝形成和扩展过程,为研究受力过程中材料损伤和裂缝演化提供一种有效手段。

To reveal the law of influence of hybrid fibers on the mechanical properties and deformation behavior of strain hardening cementitious composites (SHCC), the tensile and compressive properties of basalt-polyvinyl alcohol(PVA) fiber strain hardening cementitious composites (SHCC) were investigated at a constant fiber content of 2% (in volume fraction), different content ratios of basalt fiber and PVA fiber (i.e., 3∶1, 1∶1 and 1∶3), and different ratios of fly ash to cement (FA/C) (i.e., 1.2, 1.5 and 2.0). The direct tensile and compressive strengths of hybrid fiber SHCC with different fly ash contents were analyzed. The horizontal and vertical strain evolution and crack development of the sample during compression were discussed via digital image correlation (DIC). The results show that the compressive strength of the mixed fiber specimens is greater than that of the single fiber specimens, indicating that the hybrid fiber can effectively improve the compressive strength. At FA/C ratios of 1.2 and 1.5, the optical fiber type is B0.5P1.5 (i.e., the volume fraction of basalt fiber is 0.5% and PVA fiber is 1.5%). At a FA/C ratio of 2.0, the optical fiber type is B1P1. The optical fiber type is different for different fly ash admixtures, indicating that the fly ash admixture affects the optical fiber type. In the hybrid fiber specimens, basalt fibers mainly play a role in improving the strength, but it is not suitable for the ductility of the material. In contrast, incorporating PVA fibers can effectively enhance the material's ductility, the addition of hybrid fibers can enhance the mechanical properties. The DIC can effectively characterize the strain evolution and crack formation and propagation process of the material, thus providing an effective method for investigating the material damage and crack evolution in the loading process.
