Abstract
The invention provides hydraulically setting sealing composition based on a) a hydraulically setting compound out of the group comprising high-alumina cement, ordinary portland cement, blast furnace slag, b) protective-colloide stabilized polymer of one or more ethylenically unsaturated monomers in form of an aqueous polymer dispersion or a water-redispersible polymer powder, and c) one or more fillers.
Claims11
A coating on an external surface of a concrete structure, wherein the coating is formed by hydraulically setting on said surface a sealing composition comprising
- a) a hydraulically setting compound consisting of blast furnace slag,
- b) a protective-colloid stabilized polymer of one or more ethylenically unsaturated monomers in the form of an aqueous polymer dispersion or a water-redispersible polymer powder, and
- c) one or more fillers;
- wherein the sealing composition does not contain high alumina cement, wherein the blast furnace slag is the only hydraulically setting compound in the sealing composition, and wherein all of the surfaces of the concrete structure that are exposed to seawater are coated with the composition.
