| Summary |
Autoclaved aerated concrete (AAC) has many advantages as a new and innovative building material introduced to building construction. It is lightweight, has a high fire rating, and excellent acoustical properties. Typical AAC applications include floor and roof diaphragms, and shear walls. Bond strength between thin-bed mortar and AAC units is important to the structural performance of AAC buildings. In an AAC floor diaphragm lateral loads may be transferred from the diaphragm to a shear wall through adhesion between a grouted bond beam and the floor slab. These specimens were tested to expand the scope of tests related to bond strength in the current masonry code. There are two tests that were conducted on typical AAC specimens. The first was the direct shear test, which evaluated specimens that simulate the loading conditions of the grouted bond beam/floor slab connection. An additive called methylcellulose was used to investigate the effects of it on the strength of the bonds. The specimens were built under different humidity levels to simulate different regions of the country. Bond wrench tests were performed to investigate the flexural tensile strength of thin-bed mortar joints.
