再生混凝土断裂机理及其增强手段
Journal: Building Technology Research DOI: 10.12238/btr.v8i1.4588
Abstract
再生混凝土的断裂性能较普通混凝土差,且随着再生骨料取代率的增加而降低,大大阻碍了再生混凝土的工程应用。因此,开展再生混凝土断裂性能的研究至关重要。结合国内外最新研究现状,分别从再生混凝土断裂模型方面对再生混凝土断裂机理进行归纳总结。以此为基础进一步从再生骨料的取代率、预处理方法、掺合料加入、纤维的添加等再生混凝土断裂性能的影响因素的研究现状进行梳理与分析。研究成果对加强废旧混凝土断裂机理及力学增强措施的研究具有引导作用,为进一步提高废旧混凝土的再生利用及推广提供参考。
