Betonwerk und Fertigteil-Technik/Concrete Plant and Precast Technology | Year: 2014
The annual consumption of concrete worldwide is currently estimated at approximately 5 billion m3. Laboratory performance tests and service life calculations performed on concretes manufactured in accordance with the descriptive regulations show a relatively large range of properties relevant to durability. In Italy, cements with several main constituents have already been used for years in larger amounts than in Germany. A comparison of the application rules for external concrete components in Italy and Germany shows that the concrete-technological boundary conditions for use of the cements are distinctly different. The advantage of the last-mentioned systems would be that the concretes and their constituents could be used to even better effect based on their performance. One prerequisite for this would be a broadened quality assurance system oriented on the entire value-added chain, since this would increase the options available and, naturally, create more potential sources of errors.
