Compared to the properties of ordinary concrete, the recycled coarse aggregate concrete exhibits the lower strength and poor durability due to many pores and micro-cracks inside the recycled coarse aggregates and the old mortar attached to the aggregate surface. However, the silica nanoparticles with a high pozzolanic activity, a crystalline nucleation effect and a filling effect plays an important role in the application of modified recycled coarse aggregate concrete. Recent work on the properties of recycled coarse aggregate concrete modified by silica nanoparticles was analyzed in terms of workability, mechanical properties, durability and interfacial structure, etc. The modification mechanism of silica nanoparticles to improve the performance of recycled coarse aggregate concrete was further discussed, thus providing some theoretical and technical supports for the application of silica nanoparticles in the performance improvement of recycled coarse aggregate concrete.

再生粗骨料中存在着较多的孔隙和微裂缝及表面附着的旧砂浆,导致再生粗骨料混凝土强度和耐久性能与普通混凝土相比较差。然而,纳米二氧化硅具有高火山灰活性、晶核效应和填充效应,使其在强化改性再生粗骨料混凝土的应用中具有重要意义。基于此,从工作性能、力学性能、耐久性和界面结构等方面,针对纳米二氧化硅改性再生粗骨料混凝土性能的研究进行了分析归纳,讨论了纳米二氧化硅对其性能提升的改性机理,为纳米二氧化硅在再生粗骨料混凝土性能提升方面的应用及推广提供理论和技术支撑。

再生粗骨料中存在着较多的孔隙和微裂缝及表面附着的旧砂浆,导致再生粗骨料混凝土强度和耐久性能与普通混凝土相比较差。然而,纳米二氧化硅具有高火山灰活性、晶核效应和填充效应,使其在强化改性再生粗骨料混凝土的应用中具有重要意义。基于此,从工作性能、力学性能、耐久性和界面结构等方面,针对纳米二氧化硅改性再生粗骨料混凝土性能的研究进行了分析归纳,讨论了纳米二氧化硅对其性能提升的改性机理,为纳米二氧化硅在再生粗骨料混凝土性能提升方面的应用及推广提供理论和技术支撑。

Compared to the properties of ordinary concrete, the recycled coarse aggregate concrete exhibits the lower strength and poor durability due to many pores and micro-cracks inside the recycled coarse aggregates and the old mortar attached to the aggregate surface. However, the silica nanoparticles with a high pozzolanic activity, a crystalline nucleation effect and a filling effect plays an important role in the application of modified recycled coarse aggregate concrete. Recent work on the properties of recycled coarse aggregate concrete modified by silica nanoparticles was analyzed in terms of workability, mechanical properties, durability and interfacial structure, etc. The modification mechanism of silica nanoparticles to improve the performance of recycled coarse aggregate concrete was further discussed, thus providing some theoretical and technical supports for the application of silica nanoparticles in the performance improvement of recycled coarse aggregate concrete.
