The features of the pores in pervious concrete have a great influence on the mechanical property of the pervious concrete.
In this study, a finite element model (FEM) with random pores has been used to simulate the mechanical characteristics of pervious concrete.
First, pervious concrete specimens with two different porosities were prepared in the laboratory.
Then, the specimens were cut and the pores features were extracted based on the images of cross-sections.
Thereafter, the ellipse and roundness were introduced into a simulation model to describe the characteristics of pores including the size, area, shape, and inclined angle which have been developed randomly in the FEM using the Monte Carlo method.
In the simulation model, the aggregate and cement paste have been simplified into a composite material, and the method of determining the composite modulus of aggregate-cement paste is discussed.
The simulation results show that the shape and distribution of the pores have an obvious influence on the internal stress of the pervious concrete and the pore features can be considered reasonable for the validity of the simulations.
In addition, the composite modulus of the aggregate-cement paste can be determined by comparing the simulation and test results.
The recommended composite modulus in the pervious concrete simulation model is much lower than that of common impervious concrete.
