To investigate the structural compatibility of eco-porous concrete (EPC) and vegetation, a simulation method (sand penetration coefficient) of structure compatibility between the eco-porous concrete (EPC) and vegetation was put forward. Furthermore, the relation between sand penetration coefficient and pore characteristics were analyzed, and the technology of acquiring equivalent pore size was optimized. The results present that the new simulation method, characterized by sand penetration coefficient, can effectively assess the ability of eco-p...
