Title:
METHOD FOR THE TECHNICAL PRODUCTION OF CONCRETE ARTICLES HAVING IMITATED NATURAL STONE OR OTHER AESTHETICALLY CONFIGURED SURFACES
Document Type and Number:
WIPO Patent Application WO2004069761
Kind Code:
A3
Abstract:
The invention relates to a method for the technical production of concrete articles having natural stone or other aesthically configured surfaces. Said method enables natural stone surfaces to be imitated and/or noble artificial stone surfaces to be produced in a reproducible manner without expensive surface secondary treatment. Said method consists in adding water and cement to the homogeneously mixed admixture in a mixing device and simultaneously mixing. Concrete having visible granulation which does not stick to the base matrix is produced from the thus produced base matrix by means of the visible granulation added at the end of the mixing step. The concrete can be further processed according to known prior art and the final product need not be subjected to any further processing processes in order the make the granulation visible on the surface. Said method can be used in the production of concrete articles.
