Title:
METHOD FOR INCREASING PENETRATION DEPTH OF SILANE IN CONCRETE
Document Type and Number:
WIPO Patent Application WO/2018/082147
Kind Code:
A1
Abstract:
A method for increasing a penetration depth of silane in concrete, relating to the technical field of concrete. The method comprises the following steps: pre-processing the surface of a concrete structure to make the surface of the concrete structure clean and complete; first mixing water with absolute ethanol, and uniformly dispersing silane in a mixture of ethanol and water to prepare a silane solution; placing a preprocessed concrete structure sample in the silane solution, connecting a reinforcing bar in the sample to a negative electrode of an external power source by means of a wire, placing a conductive electrode in the silane solution, and connecting the wire to a positive electrode of the power source so as to constitute a loop; and opening the power source and applying a constant voltage. A technique provided in the method utilizes electric principles such as electroosmosis and electromigration, effectively increases a penetration depth of silane in concrete by injecting silane into pores on a concrete structure, and thus improves the hydrophobic of a surface of the concrete structure and the durability of the concrete structure. The method is less affected by an environmental factor, has a simple process, is easy to operate, and has a good effect.
