FRACTURE OF AAC AS INFLUENCED BY SPECIMEN DIMENSION AND MOISTURE

The results are presented of an experimental investigation into fracture energy and tensile softening behavior of auutoclaved aerated concrete (AAC). Fracture properties, as influenced by specimen dimension, type, and origin of AAC as well as moisture content at room temperature, are discussed. It was found that autoclaved aerated concrete is a softening material, and the fracture process can be described realistically by the fictitious crack model. Fracture properties such as the specific fracture energy depend on the specimen geometry. These and other study findings are discussed.
