Behaviour of post-installed adhesive anchors in natural stone

This work is based on the results of an experimental research related to chemical anchors in natural stone. The specific goal is to achieve the minimum embedment depth for chemical anchoring of post-installed threaded rods in basalt, sandstone and limestone support, by using epoxy resin. The reliability of theoretical formulations in the literature valid for concrete is evaluated. The applicability of some numerical models for the prediction of the bearing capacity of the anchor is then investigated, whereas the theoretical formulations are not feasible.
