摘要
再生混凝土技术作为发展生态、绿色混凝土,实现建筑、资源、环境可持续发展的主要措施之一,正日益受到人们的重视。再生混凝土耐久性能研究是再生混凝土领域中非常重要的一个研究方向。通过对国内外再生混凝土耐久性能的研究现状的剖析和深入对比,研究了再生混凝土抗碳化性能、抗冻性能、干燥收缩、徐变、抗渗性能、耐磨性能、碱集料反应以及抗硫酸盐侵蚀等性能,并就需进一步研究的相关问题提出了看法。
As one of the main ways for developing ecological and green concrete, and achieving the sustainable development of construction, resources and environment,the recycled concrete technology is an important issue.The durability performance of recycled concrete is an important investigation direction in the field of recycled concrete.Based on the extensive review and in-depth comparative analysis on the state-of-the-art of durability of recycled concrete ,the primary law of durability of recycled concrete, including carbonation resistance, freezing and thawing resistance, drying shrinkage, creep,permeation resistance, abrasion resistance, alkali-aggregate reactions, sulfate ingress resistance are unclosed.The problem that needs to be further explored and attentions that should be drawn in process of studying are also put forward.
