一、导电混凝土的用途干燥状态的混凝土的电阻率为6.54～11.4kΩm,是良好的绝缘体。但混凝土是一种多孔材料,在混凝土的内部存在着各种尺寸的孔隙,当这些孔缝中充满水时,混凝土的导电性能就会大大地增加。处于潮湿状态的混凝土,其电阻率为25～45Ω·m,这时的混凝土就 First, the use of conductive concrete The resistivity of dry concrete is 6.54 ~ 11.4kΩm, is a good insulator. However, concrete is a kind of porous material. There are pores of various sizes in the interior of concrete. When these holes are filled with water, the electrical conductivity of concrete will greatly increase. Concrete in the wet state has a resistivity of 25 to 45 Ω·m. Concrete at this time
