Micro-tears and grey discolourations in concrete products

Kobra Formen GmbH, 08485 Lengenfeld, Germany


Concrete blocks are a fundamental element for the design of spaces in many areas of life, both in the private and public sector. The constant further development and diversification of concrete blocks with regard to new formats and surfaces results in changed requirements for their production. The following article focuses on two aspects in concrete block manufacturing that can negatively affect the product quality. It concerns the causes for so-called tampershoe adhesions on concrete block moulds at the moment of demoulding during the manufacturing process as well as the formation of bloom in particular with white cement products. In close cooperation with its international customers, Kobra Formen GmbH concerns itself with the continuous further development of its concrete block moulds and has developed ways of avoid- ing these manufacturing problems from the point of view of the mould manufacturer.
