Abstract：
The strength and durability of tunnel lining concrete are directly relative to the economic efficiency and safety of a project. This paper studies the effects of admixture combined with class I fly ash mixed with single or compound nano-material with various types and physical properties on the strength of gel sand samples regardingsafety, environmental protection, economic efficiency, and construction. The physico-mechanical performances of non-powder nano-material, powder nano-material, and silica fume techniques were contrasted as the concrete binding materials. Meanwhile, an experimental test was carried out regarding the strength and durability of concrete in which the non-powder nano-material combined with fine compound admixture was added, and the results indicate that it is cost effective, environmentally friendly, and is durable.
