| Abstract | High strength and self-compacting high performance concrete are the recent development in the concrete technology. Their applications are able to provide many advantages in engineering aspects and can be developed by special controlling in mix proportion. High strength concrete can be used for reducing of size and weight of structural member which is the advantage in economical viewpoint. High performance concrete provides the advantage in the workability. Moreover, it also gives the high strength and durability. These types of concrete have been studied on many aspects but the data for fracture properties is still insufficient. In this study, the fracture properties of high strength concrete and high performance concrete are determine by analysis of experimental data. The considerate fracture properties are fracture energy and tension softening diagram. These properties are investigated by considering the effect of s/a, powder content, strength of coarse aggregate and microstructure of concrete. The results can be concluded that the coarse aggregate plays an important role in ductile behavior of concrete. The increase in strength of coarse aggregate or providing a large quantity of coarse aggregate increase the fracture energy. Furthermore, the fracture energy is increased by the decreasing of water-cementitious materials ratio. This result comes from the effect of microstructure in concrete. However, this effect will be less in the higher strength range. In addition, the brittle behavior of concrete corresponding to time can be observed by comparing the tension softening diagrams with time. The tension softening diagram can be represented by the one-fourth bilinear model. |
