Abstract:
The tests covered in this paper were intended to determine the holding strength of several designs of anchors for securing cantilever forms to mass roncrete surfaces. The investigation consisted of the fabrication of four blocks of low-strength, 6-in. aggregate concrete in which a total of 48 anchors wxc embedded and tested at ages ranging from 24 to 72 hr. The results in-dicate that, under the test conditions used, adequate holding strength was dc-veloped in practically every case by the time the concrete was 3 days old.
