Dry mortar, mortar slurry and method for producing semi-rigid coatings

摘要

The present invention relates to a dry mortar and a mortar slurry, and a method for producing semi-rigid coatings. In one embodiment, the dry mortar and/or mortar slurry comprises a cement, a very fine component, and a superplasticizer and is free of silica fume, wherein the mortar slurry can be applied at an asphalt framework temperature between 55 and 80 °C, and a compressive strength of at least 100 N/mm2 is reached after 28 days. In a further embodiment, the dry mortar and/or mortar slurry additionally contains a gelling agent to reduce the propensity of the mortar slurry to flow out.
