In this paper, the conception and classification of Green-growing porous concrete (POC) is introduced. POC is made of single-sized coarse aggregate, Portland cement, admixtures, chemical admixtures, water, et al. It should be properly mixed before cast in mould. Because of its large-pore structure, POC have much ecological and environmental value. In the case of be used as greening concrete which placed in highway side, POC’s compressive strength should be higher than 15MPa, at the same time, its valid porosity content should be at the range of 25% and 30%.
