Galvanic metal anode embedded in a hydraulic binder, comprising a latent-hydraulic aluminosilicate glass and an alkaline activator

摘要

Galvanic metal anode comprising at least one metal, or at least one metal alloy, incorporated in a hydraulic binder, in which the hydraulic binder comprises K, Ca, aluminum silicate, optionally Li, Na and Mg, as well as the following components: a) latent hydraulic silicate glass solution with a ratio (CaO + MgO + Al2O3) / SiO2 1 and b) alkaline activator in the form of alkaline soluble glass with the molecular formula (I) to (M2O) * x (SiO2) * y (H2O) (I) with the following meanings M = Li, Na, K a = 0-4 as well as x = 0-5 and y = 3-20, in which the molecular relationship of Ca / SI 1, the molecular ratio of Al / Si 1 and the molecular ratio of M / Si 0.1
