Abstract：A composite inorganic waterproof and leak sealing materials was formed by adding nano modified complexes to in-organic waterproof and leak sealing materials.The compressive strength,impermeability pressure,and bonding strength of the compos-ite inorganic waterproof and leak sealing materials were tested.The influence of nano modified complexes on the hydration process of composite inorganic waterproof and leak sealing materials was explored using setting time,hydration heat,and chemically bound water,and analyzed by SEM.The results showed that the optimal waterproof and leak sealing effect was achieved when the dosage of nano modified complexes to inorganic waterproof and leak sealing materials was 0.10％the compressive strength is 110％of the reference group,the flexural bonding strength,tensile bonding strength,and specimen impermeability pressure have been improved by 24％,50％and 41％respectively,compared to the benchmark group.Adding nano modified complexes to inorganic waterproof and leak sealing materials can promote hydration,fill pores to make the structure denser,improve bonding performance,impermeability,and mechanical properties.
