Abstract
A large experimental campaign was completed with the objective to determine how concrete composition and age affect the tensile load capacity of mechanical anchors with concrete cone breakout, tested in three different normal-strength concretes. Structural tests for cast-in headed stud anchors were performed at 28 and 70 days and compared to results obtained on post-installed undercut anchors. The concretes were fully characterized in terms of Young's modulus, compressive and tensile strength, and fracture energy. The evolution of the concrete compressive strength is consistent with the aging function proposed in codes. Because the history of environmental conditions influences the development of material properties with age, three different curing conditions are considered for the material characterization, including indoor moist-curing and outdoor storage with the slabs. The structural data clearly show a pronounced aging effect, even after normalization by compressive strength, regardless of the curing protocol considered.
