摘要
介绍了纳米材料的一些特性,讨论了纳米SiO2及硅粉对混凝土强度和耐久性能的改善作用。纳米SiO2及硅粉作为外掺料可制备高性能混凝土.纳米材料作为外掺抖还可用以制备具有特殊功能的混凝土。例如,添加纳米金属氧化物可制备智能混凝土和环保混凝土。添加纳米金属粉末可制各电磁屏蔽混凝土等。
Some characteristics of nano-materials are introduced Good effect of nano-SiO2 and silica fume on concrete are discussed, when they are mixed into high performance concrete. Simultaneity nano-materials take important role in special function concrete, such as intelligent concrete and environmental protection concrete can be elaborated by adding nano metallic oxide, and electromagnetism shield concrete by nano-metal powder.
