Mehraxiale Festigkeit von Hochieistungsleichtbeton - Anwendungspotenzial im Fertigteilbau

Research output: Contribution to specialist publicationFeature article/contribution (Feuilleton)Contributedpeer-review



The applications of high-performance lightweight concrete to provide multiaxial strength in precast construction are discussed. The lower weight of the material is increasingly being used to construct facades, roof elements, and ridge beams. Structures have become more delicate and lighter, and the span of precast elements greater, that leads to increased and sometimes multiaxial stress on supports, joints or load transfer points such as the crane transport lifting points or anchoring points of prestressing tendons. Multiaxial compression tests on high-performance concretes are carried out to determine the behaviors of the lightweight concrete. The tests are completed on a one piece triaxial test machine, with each axis having a rigid bearing and a cylinder with a capacity of 5,000 kN compression force or a 500 kN tensile force. The lightweight gravel with the higher uniaxial grain strength and grain density probably has higher multiaxial load-carrying capacity and grain strength.
