不同纤维对透水混凝土的性能影响研究综述

Review of the Impact of Different Fibers on the Performance of Pervious Concrete

  • 摘要: 近年来,我国城市化发展迅速,随之而来的是许多环境破坏以及资源短缺的问题,为了应对上述问题,我国开始大力推行海绵城市的建设。绿色的建筑材料透水混凝土便是海绵城市中的重要材料,与传统混凝土相比,其优异的透水性能能够有效排除地面积水,减少城市内涝现象,同时,其透气性以及吸收噪音的能力也要优于传统混凝土。然而,透水混凝土力学性能的不足是其应用有限的关键原因,因此,国内外学者开展了大量对其力学性能以及透水性能的研究。研究发现,多种纤维的加入能够在保证一定透水性能的前提下改善其力学性能。基于此,本文对不同种类的纤维及其不同掺量对透水混凝土的影响进行了综述。

     

    Abstract: In recent years, rapid urbanization has been experienced in China, leading to numerous environmental damages and resource shortages. To address these issues, the construction of sponge cities has been vigorously promoted. Pervious concrete, as a green building material, is considered an important material in sponge cities. Compared to traditional concrete, its excellent permeability can effectively eliminate surface water accumulation and reduce urban flooding. Additionally, its breathability and noise absorption capabilities are superior to those of traditional concrete. However, the limited mechanical properties of pervious concrete have been identified as a key reason for its restricted application. Consequently, extensive research on its mechanical and permeability properties has been conducted by scholars both domestically and internationally. Research has found that the addition of multiple fibers can improve their mechanical properties while ensuring a certain level of water permeability. Based on this, a review of the impact of different types and amounts of fibers on the performance of pervious concrete has been conducted in this paper.
