Tensile Behaviour of Post-Installed and Cast-In Mechanical Anchors in Early Age Concrete

This thesis discusses the behaviour of post-installed and cast-in mechanical anchors in early age concrete. The current design models available deal with the behaviour of these anchors in mature concrete i.e >28 days. However, these anchors are loaded before reaching full maturity of the concrete in the industry. The conclusion drawn from this study offers insights into the performance of cast-in headed anchors with void formers in early-age concrete and provides a new prediction model for the pull-out failure through the void. Furthermore, the research studies provide understanding of the performance of screw and expansion post-installed anchors in early-age concrete and outlines the suitability of current prediction models for applications in early-age concrete.
