Abstract

In order to explore the effect of fly ash on the pore structure and comprehensive strength properties of concrete, the effect of contents and particle size distribution of fly ash on the grade pore porosity and strength of the concrete were analyzed by mercury intrusion method. The results show that, decreasing the particle size of the fly ash leads to decrease of the porosity and less of the more harmful hole and harmful hole, while the harmless hole and the less harmful hole gradually increase. In addition, through the calculation on the fractal dimension of concrete grade pore porosity , it is found that there is a good correlation between the fractal dimension and strength of the concrete.
