Carbon fiber reinforced concrete as well as preparation method and application thereof
The invention relates to carbon fiber reinforced concrete as well as a preparation method and application thereof. The carbon fiber reinforced concrete is prepared from the following raw materials: cement, river sand, gravel, a water reducing agent, water and carbon fibers. According to the carbon fiber reinforced concrete provided by the invention, on the premise that only the carbon fibers are added into the admixture, components such as a dispersing agent or a coupling agent do not need to be additionally added, and by adding the mineral admixture (river sand), the bonding strength of the carbon fibers and a concrete matrix can be improved, the influence of an interface transition area on the concrete performance is reduced, and the carbon fiber reinforced concrete with high dynamic splitting tensile resistance is obtained.
本公开涉及一种碳纤维增强混凝土及其制备方法和应用，所述碳纤维增强混凝土的组成原料由水泥、河砂、碎石、减水剂、水和碳纤维组成。本公开提供的碳纤维增强混凝土在外加剂仅添加了碳纤维的前提下，无需额外加入分散剂或偶联剂等组分，通过添加的矿物掺合料(河砂)就可以提高碳纤维与混凝土基体的粘结强度，降低界面过渡区对混凝土性能的影响，得到具有高抗动态劈拉性能的碳纤维增强混凝土。
