| 中文摘要: |
| 疏浚砂资源化利用是推动“无废城市”和“绿色航道”建设的重要举措。疏浚砂虽与天然河沙具有相似化学组成，但具有颗粒级配单一、吸水率大、含泥量大等缺陷，是疏浚砂资源化利用的难点。本文分别从含泥量与疏浚砂掺量两个方面研究对混凝土工作性能、力学性能、耐久性能的影响。通过分析疏浚砂再利用的研究现状，提出了现阶段疏浚砂资源化研究与应用的方向，为疏浚砂资源化利用提供新思路。 |
| 英文摘要: |
| The resource utilization of dredged sand is an important measure to promote the construction of “no waste city” and “green channel”. Although dredged sand has similar chemical composition with natural river sand， it has the defects of single particle gradation， large water absorption and large mud content， which is the difficulty of resource utilization of dredged sand. In this paper， the effects of mud content and dredged sand content on the working performance， mechanical properties and durability of concrete are studied from two aspects. By analyzing the research status of dredged sand reuse， this paper puts forward the direction of research and application of dredged sand resource utilization at the present stage， and provides new ideas for the resource utilization of dredged sand. |
