The long-run behavior of adhesive fastenings in concrete depends mainly on the pure adhesive which is not yet solved exactly. By contrast the long-time behavior of the admixed aggregate (mainly quartz sand) is known much better. It affects the shrinkage behavior, the development of heat during the hardening process and the time-displacement relation of constantly loaded anchors in a positive way. In order to minimize the time-dependent uncertainties, as the first step, experiments of adhesive anchors without glue (just quartz sand) were accomplished and their short- and long-term behavior is compared with common adhesive systems. The main difference of the new system is the load transfer just by aggregate interlock. By reason of the high compression strength of quartz also elevated loads can be achieved.
