Test procedure for measurement of masonry flexural bond strength (Bond Wrench Test). Hollow Clay Tile Wall Test Program

This document describes a procedure for determining the flexural bond strength of in situ hollow clay tile bed joints by physical testing of selected joints. This procedure is based on the requirements of ASTM C1072-86. The principal objective of this test is to provide a simple and economical means for the determination of comparative values of flexural bond strength by physical testing of each joint of non-reinforced existing hollow clay tile masonry.
