Summary

Even though there are numerous research projects on high performance normal weight concrete (HPC) only little is known on the long-term behaviour of those concrete whose dense aggregates content is partly (HPLWAC) or completely (HPLC) replaced by lightweight aggregates. In this cases the interaction of a high performance matrix and the water stored in the pore system of the LWA and their influences on creep and especially on shrinkage were of particularly interest. In pursuance of this aim a comparison between high performance concrete without and with LWA – both in the same range of strength – was needed. Besides this the influence of sealed and unsealed specimen surfaces has been investigated. The deformation measurements for shrinkage were started at an age of 20 … 28 h; the early age shrinkage was not observed.
