PURPOSE: A penetrating waterproof material is provided to form a gel in a state that the waterproof material penetrates from the surface of a concrete and the bottom of pores, thereby improving strength of concrete and making charging possible regardless of the depth of the pores. CONSTITUTION: A penetrating waterproof material is obtained by adding NaOH solution into the mixture solution of sodium silicate and aluminum silicate in which liquid sodium silicate(or Na2OSiO2) as an adhesive liquid aluminum silicate and liquid aluminum silicate as a reinforcing agent is mixed with the molar ratio of 1:1 and stirring the materials in a reactor rotating at 500 RPM at 50-80°C for 30 minutes. The weight ratio of the NaOH solution to the total weight of the mixture solution is 1:0.3-1:0.7. |
