As an environmentally friendly material, the ecological porous concrete has made certain progress in mix design, physical and mechanical properties, and plant compatibility etc. However, the relationship between its complex internal pore structure and macroscopic properties still needs to be further studied. In the paper, the compressive strength, porosity, and fractal dimension of pore structure of the ecological porous concrete with coarse aggregate particle sizes ranging from 19 to 26.5 were investigated. The standard cubic specimens were te...
