Carbon nanotube-modified concrete as well as preparation method and application thereof
The invention relates to carbon nanotube-modified concrete and a preparation method and application thereof. The carbon nanotube-modified concrete is composed of cement, fine aggregate, coarse aggregate, a water reducing agent, water and carbon nanotubes, wherein the carbon nanotubes are multi-walled carbon nanotubes, and the fine aggregate is river sand with a fineness modulus of 2.8. The carbon nanotubes disclosed by the invention can improve the typical brittleness characteristic of a concrete material, and the finally obtained carbon nanotube-modified concrete has excellent impact resistance and relatively high toughness and deformation resistance, so the serious safety problem of a concrete structure exposed under an impact loading condition can be solved to a certain extent, and the service life of an engineering structure easily suffered from impact load can be effectively prolonged.
本公开涉及一种碳纳米管改性混凝土及其制备方法和应用，所述碳纳米管改性混凝土的组成原料由水泥、细骨料、粗骨料、减水剂、水和碳纳米管组成，所述碳纳米管为多壁碳纳米管，所述细骨料为细度模数为2.8的河砂。本公开的碳纳米管能够改善混凝土材料典型的脆性特征，最后得到的碳纳米管改性混凝土具有优异的抗冲击性能，较高的韧性和抗变形能力，一定程度上可解决混凝土结构在冲击加载条件下暴露出的严重的安全性问题，可有效提高易遭受冲击荷载作用的工程结构的服役寿命。
