Fracture mechanics parameters of autoclaved aerated concrete

Trunk, B. / Schober, G. / Helbling, A.K. / Wittmann, F.H.

The influence of the expanding direction of Autoclaved Aerated Concrete (AAC) on the nonlinear fracture mechanics parameters is determined on three different types of AAC. The nonlinear fictitious crack model introduced by Hillerborg et al. is used. Based on the RILEM recommendation AAC 13.1, wedge-splitting tests have been carried out on three different types of AAC. For each AAC type, specimens were prepared so that the ligament area was parallel or vertical to the expanding direction. It was found that the specific fracture energy G_f and the tensile strength f_t differ in the two directions. All three concrete types show less brittle behaviour when the ligament area is parallel to the expanding direction.
