As Ordinary Portland cement matrix porous materials is expected good performance of adsorption and filtration in wastewater treatment, but the interconnected pores structure has enormous influence on its adsorption and filtration performance, Ordinary Portland cement matrix porous materials is prepared by introducing zeolite powder, metakaolin, admixture, and foaming agent into Portland cement slurry, A relationship between interconnected pore structure of porous materials which has multistage pore structure and preparation parameters (water cement ratio, curing temperature and humidity) is investigated combined with Image analysis software (Image-Proplus), the result shows that material component, average pore diameter and pore diameter distribution have the different effectiveness on interconnected pore structure, appropriate water cement ratio curing temperature, its helpful to be the most effective method to increase the interconnected pores percentage.
