An experimental study on the fracture energy of foamed concrete using v-notched beams

摘要

In recent years, foamed concrete has experienced a lot of revolutions as an alternative replacement of normal concrete in structural engineering. A low range of densities of foamed concrete can be obtained for various applications. The main advantages of foamed concrete as structural component are its characteristics as high strength with low density, good serviceability and lightweight. Therefore, many interests and studies were conducted to investigate the strength and mechanical properties of foamed concrete. These studies, however, not consider the investigation on fracture energy of foamed concrete which is the main parameter that govern the damage and crack mechanisms. The objective of this study is to experimentally investigate the fracture energy of foamed concrete using beam specimens with V-notch under the three-point bending test.
