| 摘 要： | 针对目前存在的水泥混凝土路面裂缝无机修补材料的界面粘结强度低,且水泥路面早期裂缝一般为细小的微裂缝的问题,采用颗粒较小的超细水泥、磨细矿渣(GGBFS)及其他外加剂制备了水泥混凝土路面裂缝灌浆材料,对该类材料的力学性能和界面粘结性能进行研究,并通过微观试验分析揭示了材料宏观性能的改性机理。研究表明:磨细矿渣能通过微粒填充作用使超细水泥浆体的微观结构变得更密实,提高材料稳定期的力学强度;适量的磨细矿渣能改善灌浆材料的粘结界面微观结构,增加界面粘结强度。 |

| Abstract: | Aimed at problem that present inorganic mending materials of cement concrete pavement crack are weak in interfacial bond strength and the minuteness of the early cracks,concrete pavement crack mending material was prepared by microfine cement,granulated ground blast furnace slag(GGBFS) and other admixtures,which are superfine.Compression strength,bending strength and interfacial bond strength were studied,and modification mechanisms were discovered by microstructure test.The result shows that mechanical strength is improved with mixing of GGBFS,which makes microstructure of harden paste solider dense;interfacial bonding strength is increased by certain content of GGBFS,which improves interface microstructure. |
| Keywords: | road engineering microcrack mending material experimental research GGBFS microfine cement mechanical strength bond strength |
