Structural health monitoring intelligent concrete for airport and preparation method of structural health monitoring intelligent concrete
The invention relates to structural health monitoring intelligent concrete for airports and a preparation method thereof, and the method comprises the following steps: adding a polycarboxylic acid water reducing agent into water, and mixing to obtain a water reducing agent solution; adding carboxylated multi-walled carbon nanotubes, silica fume and fly ash into the water reducing agent solution, and mixing to obtain a carbon nanotube suspension; performing ultrasonic treatment on the carbon nanotube suspension to obtain a carbon nanotube dispersion liquid; and adding the carbon nanotube dispersion liquid into the dry material mixture, and mixing to obtain the structural health monitoring intelligent concrete for the airport. Compared with the prior art, the conductivity of the concrete can be effectively improved, so that the concrete has the function of monitoring structural health.
本发明涉及一种机场用结构健康监测智能混凝土及其制备方法，该方法包括以下步骤：将聚羧酸减水剂加入水中，混合，得到减水剂溶液；将羧基化多壁碳纳米管、硅灰和粉煤灰加入减水剂溶液中，混合，得到碳纳米管悬浮液；对碳纳米管悬浮液超声处理，得到碳纳米管分散液；将碳纳米管分散液加入干料混合物中，拌和，得到机场用结构健康监测智能混凝土。与现有技术相比，本发明能够有效提高混凝土的电导性，从而使其具有监测结构健康的功能。
