水泥基复合材料纳米化改性的研究

水泥基材料中70％为纳米尺度的C—S—H凝胶,因此对水泥基材料进行纳米改性具有很好的基础,我国有一些关于纳米基材料在混凝土中应用的研究,但目前还不可能在实体工程中采用这种混凝土。纳米在水泥科技中的应用应首先是纳米技术与一些技术含量高的水泥基复合材料的结合。研制具有超高性能(力学)以及特定功能的纳米水泥基复合材料是目前水泥基材料纳米化改性的研究方向。

Study on the nano modification of cement-based composites

As 70% of nano size C-S-H gel consists in the cement-based materials, modification of the cement-based materials with nano technology is possible. At present, many research works are done on the concrete manufacture using nano size admixture, but this kind of concrete could still not be used in practical engineering. The utilization of nano technology in cement-based materials should focus on high-tech cement based composites. Using nano technology to prepare cement-based composites with super high dynamic performance or special functions should be the main researching direction for nano modification.
