Microcapillary composite matrix consists of an electroconductive paint or coating on mortar or cement concrete on the surface layer of the concrete. The fraction of capillaries with a diameter /~ 50 nm is over 25%, preferably over 35% and higher than the fraction of microcapillaries to the total capillary porosity of the underlying concrete or mortar. The microcapillaries are interconnected and form a network with the capillary network in the concrete. The matrix has high ion conductivity, is resistant to weak acids and has a resistivity less than 25, preferably less than 5 ohm/cm. Its negative pore water pressure is higher than that in the concrete or mortar. An Independent claim is also included for the production of the matrix by applying a suitable paint. |
