Abstract: The present invention relates to a primer composition for dehumidification and a waterproofing method using the same. The generation of pinholes, which can be generated afterward by the pores of a matrix, and a pocket is prevented in advance and adhesion between the matrix and a waterproof layer is improved greatly by filling the pores formed on the matrix and adding powder-formed calcium carbonate to a primer to be applied to the surface of the matrix so as to remove moisture contained in the surface of the matrix.

Abstract: PURPOSE: A concrete accelerating agent is provided to secure liquid stability under oversaturation of aluminum oxide and sulfate ion, and to show excellent quick setting power, cohesive property and early strength by increased content of aluminum oxide and sulfate ion. CONSTITUTION: A manufacturing method of a concrete accelerating agent comprises the steps of: manufacturing aluminum hydroxide solution by dissolving a mixture comprising aluminum hydroxide in hydrofluoric acid (S1); manufacturing mixed solution of aluminum hydroxide and aluminum sulfate by dissolving aluminum sulfate in the aluminum hydroxide solution (S2); and controlling pH of the mixed solution and injecting a stabilizer (S3). In the step S1, sulfuric acid is more added when adding the hydrofluoric acid. The stabilizer is a reaction stabilizer for increasing reaction stability, and comprises amines. The stabilizer is an oversaturated liquid stabilizer for securing stability of the mixed solution, and comprises manesiums. The concrete accelerating agent comprises: 8-15 wt% of Al(OH)3; 0.1-0.5 wt% of phosphoric acid group; 16-18 wt% of HF; 1.5-2.5 wt% of magnesiums; and 20.30 wt% of water.
