Evaluation of Vinylester Resin for Anchor Embedment in Concrete. Repair, Evaluation, Maintenance, and Rehabilitation Research Program
Abstract
The purpose of this study was to evaluate the load-carrying capacity of anchors embedded in concrete with Hilti's HEA vinylester resin capsules. Anchors installed in vertical drill holes under dry and submerged conditions were tested to determine tensile and shear load capacities. For the range of parameters in this study (hole condition, embedment length, and test age), results of pullout tests on threaded-rod anchors installed in dry holes were remarkably consistent with an overall average tensile capacity of 105 kips at 0. 1-in. displacement and an average ultimate load of approximately 125 kips. In comparison, results of pullout tests on anchors installed under submerged conditions were relatively erratic with an overall average tensile capacity of 36 kips at 0.1-in. displacement and an average ultimate load of 48 kips. Obviously, the tensile load capacity of anchors embedded in concrete with vinylester resin capsules is significantly reduced when the anchors are installed under submerged conditions. The significantly reduced tensile load capacity of anchors embedded in concrete with vinylester resin capsules under submerged conditions should be recognized in any design of anchor systems for underwater applications.
