Grouted Post-Installed Concrete Anchorages

The objective of this project is to investigate the feasibility of cement-based grouted anchors less than 1” in diameter in lieu of adhesive-based systems with the focus on developing a basic understanding of the primary design variables: embedment type (i.e. threaded, headed, or deformed shanks), hole details, and grouting materials (i.e. standard high-strength grouts and ultra-high performance concretes (UHPC) with and without expansive additives). The research team will conduct proof of concept testing with a focus on the ultimate limit state and failure modes of the systems. Other key variables such as anchorage group and edge distance effect may be considered.
