Abstract EN
The fracture parameters and fracture relational curves of the concrete containing nano-SiO2 and fly ash with different relative notch depth of the notched beam specimens were measured by means of three-point bending method.
The results indicate that the relative notch depth of the notched specimens has great effect on ac, KICini, KICun, GF, CMODc, and the fracture relational curves of the concrete containing nano-SiO2 and fly ash.
There is a tendency of increase in ac and CMODc with the increase of relative notch depth, while KICini, KICun, and GF are decreasing gradually with the increase of relative notch depth of the notched beam specimens.
Besides, when the relative notch depth increases from 0.2 to 0.5, the nonlinear stage of the curve becomes shorter and shorter, and the descent stage of the curve becomes sharper and sharper.
The fracture parameters of ac, KICini, KICun, GF, and CMODc and the fracture curves are sensitive to the relative notch depth, while CTODc may be not sensitive to the relative notch depth of the specimens of the concrete containing nano-SiO2 and fly ash.
