Abstract
An experimental study was conducted on the anchorage performance of post-installed anchors according to aged concrete. An aging simulation was performed by assuming the surface aging depth was 10, 20, 30, 40, 50mm and setting the compressive strength of concrete after 40, 30, and 20 years of construction to 10MPa, 15MPa, and 21MPa. As a result of this experiment, for both the 30-year and 40-year aging simulation groups, the pull-out strength before the aging simulation depth of 30mm showed a difference of less than 10% from the test with a 24MPa compressive strength. The strength decreased rapidly after the simulation depth of 40mm; it was found to show a difference within 20% compared to 18MPa concrete. In addition, the pulling strength increased as the embedding depth of the anchored concrete increased. The verticality of the anchor and the drilling depth of the concrete were affected at the aging simulation depth of 10 to 30mm.
