Shear bond strength of adhered thin masonry veneer with traditional and polymer modified mortars
Highlights Use of adhered thin masonry veneers (ATMV) is common in North American construction. Traditionally Type N and S mortar has been used for ATMV installations. Lack of standard design and installation guide for ATMV resulted in poor performance. Type S mortar cannot reach the minimum strength of 0.34 MPa required by ASTM C1780. Polymer modified mortar resulted in shear bond 12 times stronger than type S mortar.
Abstract There have been numerous cases of bond failures in adhered thin masonry veneer (ATMV) applications, probably due to lack of knowledge and the lack of any standards for design and installation of ATMV. The physical and mechanical properties of three types of ATMV units and two types of mortars, one traditional and one polymer modified, and the shear bond strengths of different combinations of these stones and mortars were measured and evaluated. The outcomes are that bond strength is significantly improved when polymer modified mortar is used, while there is no clear relationship between identified material properties and bond strength.
