METHOD FOR FINISHING SURFACE OF CEMENT COMPOSITION, AND CEMENT STRUCTURE FOR WATER USE SECTION

摘要

PROBLEM TO BE SOLVED: To provide a method for finishing the surface of a cement composition, in which an excellent water permeation preventive effect is exhibited by a small amount of a resin emulsion.SOLUTION: The method for finishing the surface of the cement composition comprises the steps of: casting the cement composition; spraying the resin emulsion having glass transition temperature within a range of -10°C to 20°C on the cast cement composition until the cast cement composition is hardened; and mixing the sprayed resin emulsion in the cement composition. According to the method for finishing the surface of the cement composition, the water permeation preventive effect of the same level as when the whole surface is finished by using a trowel can be exhibited by a smaller amount of the resin emulsion.SELECTED DRAWING: None
