As the applicability of Linear Elastic Fracture Mechanics to concrete strongly depends on an used specimen size, it is necessary to consider the non-linearity resulting from the existence of a fracture process zone in front of a notch tip for the estimation of fracture toughness using a small specimen. So, in this study the estimation of fracture toughness based on analysis of a fracture model considering the nonlinearity of a notch tip was called an indirect estimation, the applicability was investigated experimentally.
