| 摘要 |
The invention relates to an electrically conductive microcapillary composite matrix produced by depositing on mortar or concrete a paint or coating material which contains at last one of the following compounds: aluminium silicate of the empirical formula aM2O*bAl2O3*cSiO2, at a ratio c/b in the region of 1 to 40, preferably in the region of 5 to 20, and a ratio a/b in the region of 1 to 25, preferably in the region of 5 to 15, where M = Li, Na, K; aluminium hydroxo complex of the empirical formula MxAl(OH)y, where x is between 1 and 3, y between 4 and 6 and M = Na, K; aluminium phosphates, preferably condensed aluminium phosphates in combination with water-soluble alkali silicates. The electric conductivity of the paint or coating material is achieved by the admixing of electrically conductive pigments and/or fibrous materials. The specific electric resistance of the microcapillary composite matrix, measured at the surface, is less than 25 Ohm.cm, preferably less than 5 Ohm.cm.
