Abstract: An experimental research program was undertaken at the University of Florida with funding from the Concrete Research Council and various grout manufacturers to determine the behavior of grouted anchors and to develop rational design procedures for grouted anchor installations. For purposes of this research, a grouted anchor was defined as an anchor (headed or un-headed) installed into a hole in hardened concrete with a structural grout (cementitious or polymer). Grouted anchors typically have hole diameters that range from 150-300% larger than the anchor diameter. This is different from adhesive anchors, which typically use a polymer material with an unheaded anchor installed in a hole diameter only 10-25% larger than the anchor diameter.

This paper presents the results of this research, including 229 tests of both headed and un-headed anchors installed using six cementitious and three polymer grouts. The results indicate that the behavior of unheaded grouted anchors is similar to that of adhesive anchors while the behavior of headed grouted anchors is similar to that of cast-in-place headed anchors. For some grout products, a bond failure at the grout/concrete interface is possible and needs to be considered.
