Infra-lightweight concrete – Potentials for the precast industry
I.) Concrete properties and production
The idea of expanding the range of lightweight concretes to include lower bulk densities in order to offer interesting thermal solutions has already been successfully implemented in practice by working groups in Munich and Berlin [1-3]. Both approaches differ primarily in the choice of the lightweight aggregate used. Whereas a combination of expanded clay and expanded glass is used for the lightweight concrete of Callsen/Thienel [1], Schlaich et al. [2, 3] used only expanded clay aggregate. There are also other approaches, such as [4], that use only expanded glass as a lightweight aggregate.
