Abstract

A dry one-component alkali metal silicate cement composition contains the following components: PA0 (a) condensed aluminum phosphate or condensed aluminum/iron phosphate as hardener in amounts between 2-10% by weight, PA0 (b) rounded quartz sand having a grain size between 0.01 and 0.5 mm in amounts of 30-70% by weight, PA0 (c) clay constituents in amounts of 10-40% by weight, PA0 (d) kieselguhr in amounts of 1-5% by weight, PA0 (e) mineral oil in amounts of 0.05-1% by weight and PA0 (f) solid pulverulent sodium silicate, potassium silicate or mixtures thereof in amounts of 10-25% by weight. The composition is free of surfactant. When combined with water the cement is slow to set into an acid-resistant mortar.
