| titleOfInvention | Composite products made of concrete |
| abstract | Composite type concrete products consisting of a layer of concrete containing a biocide and a layer of a biocide-free concrete. The biocide-containing layer has a thickness which is 5 -20% of the thickness of the composite product. The content of biocide in the biocide-containing layer is 50 - 2000 ppm. The biocide is a salt or a mixture of salts of the metals copper, chromium, tin and zinc. A process for producing the concrete products consists of the following steps: A concrete paste is prepared where part of the constituent water comes from a solution of a metal salt or a mixture of metal salts. The concrete paste is poured into a mold in an amount which gives the biocide-containing layer a desired thickness. A concrete paste is prepared which does not contain biocide, and is poured into the mold in such an amount that the composite product reaches the desired thickness. The solution of metal salts has a pH of 3 - 4. The anions in the solution of metal salts are sulphate ions. The composite products of concrete can be used as paving stones, building elements, roof tiles and drainage pipes. |
