摘要:
针对南方湿热地区桥面铺装易开裂、耐久性下降等问题,选取玄武岩纤维作为混凝土增强材料,在室内模 拟标准、湿热 2 种养护环境,设计塑性收缩试验、干燥收缩与湿度分布试验以及圆环约束开裂试验,探究湿热环境 下玄武岩纤维桥面混凝土的早期开裂行为。 结果表明:湿热环境下,玄武岩纤维桥面混凝土塑性开裂得到抑制,其 单位面积总开裂面积大幅减小,较基准混凝土减少了 76. 5%;玄武岩纤维桥面混凝土内部相对湿度的变化为其干 缩变形发展的驱动力,通过掺入纤维可以减缓混凝土板内部相对湿度下降从而抑制其干燥收缩开裂,相比于基准 混凝土板,纤维混凝土板中心处与角隅处的 28 d 干燥收缩变形分别降低了 27. 5%、25. 5%;玄武岩纤维的掺入能够 抑制混凝土环的约束开裂,提高混凝土抗裂性。
Abstract:
Aiming at the problems of cracking and the durability reduction in hot and humid areas of southern China, basalt fibers were selected as concrete reinforcement materials. In simulated standard, hot, and humid curing environments indoors, the plastic shrinkage test, drying shrinkage test, humidity distribution test and circular ring restrained test were designed to explore the early cracking behavior of basalt fiber bridge deck concrete in hot and humid environment. The results showed that plastic cracking of basalt fiber bridge concrete was restrained in hot and humid environment. Compared with the reference concrete, its total cracking area per unit area was significantly reduced by 76.5%. The change of relative humidity in basalt fiber bridge deck concrete was the driving force for its development of drying shrinkage deformation. The decrease of relative humidity in the concrete slab could be slowed down by adding fiber, so as to inhibit its drying shrinkage cracking. The 28 d drying shrinkage deformation at the center and corner of the fiber reinforced concrete slab was 27.5% and 25.5% lower than that of the reference concrete. Besides, the incorporation of basalt fibers could inhibit the restrain cracking of concrete rings and improve cracking resistance of concrete.
