Foam glass aggregate is produced in a controlled production process. Due to its low density and thermal conductivity foam glass aggregate offers a broad variety of applications. Based on extensive laboratory tests foam glass aggregate is investigated in the scope of a joint research project performed at Vienna University of Technology and University of Innsbruck. The mechanical properties of single grains are investigated by uniaxial compression tests on cut foam glass prisms. The uniaxial compression test shows both a linear-elastic and a plastic behavior in the stress-strain relationship. A large-scale laboratory test was developed for the determination of the load-deformation behavior of foam glass aggregates taking into account the grain size distribution and the conditions during the compaction process in field. Deformation modulus can be directly derived while for the determination of the stiffness modulus the theory of the elastic-isotropic half space needs to be addressed. The time dependent load-deformation behavior of foam glass aggregate is determined from confined compression tests in an oedometer. Further confined compression tests with foam glass aggregate samples with different grain properties are investigated.
