METHOD OF PREPARING ENVIRONMENT-FRIENDLY CRACK REPAIRING AGENT FOR CONCRETE STRUCTURES USING INORGANIC MATERIALS AND METHOD OF COATING SAME

摘要

The present invention relates to a method of preparing an environment-friendly crack repairing agent for concrete structures using inorganic materials and a method of coating the environment-friendly crack repairing agent for concrete structures using the inorganic materials. A method of preparing an environment-friendly crack repairing agent for concrete structures using inorganic materials according to the present invention comprises: a first step of mixing 20 to 40 total mass% of distilled water with 0.1 to 1.0 total mass% of a surfactant to produce a first solution; a second step of mixing 15 to 40 total mass% of potassium, 15 to 60 total mass% of sodium, and 1 to 10 total mass% of lithium to produce a second solution; a third step of mixing the first solution with the second solution to produce a third solution; a fourth step of mixing 1 to 10 total mass% (the third solution mass%) of distilled water with 1 to 10 total mass% (the third solution mass%) of nanomaterial to produce a fourth solution; and a fifth step of mixing the third solution and the fourth solution that are the mixed solutions. Accordingly, the environment-friendly crack repairing agent for concrete structures of the present invention provides an effect that even nonprofessional is capable of performing homogeneous construction through a simple coating method by a liquid type crack repairing agent using inorganic materials only as raw materials. Further, the present invention provides effects that crack portions are capable of being repaired, and stable crack repairing and performance are capable of being improved compared to the prior art only by coating the environment-friendly crack repairing agent for concrete structures on fine cracks with a crack width of 1 mm or shorter several times without an additional construction procedure.;COPYRIGHT KIPO 2016
