The present invention relates to a concrete polishing method comprising an environment-friendly material. More particularly, the concrete polishing method comprises: a surface treating step of grating a surface layer of concrete floor; a reinforcing agent applying step of applying a reinforcing agent to the surface layer of the concrete floor; and a reinforcing agent penetrating step of making the reinforcing agent permeate through the concrete floor by drying the concrete floor. The reinforcing agent comprises: 5-50 wt% of potassium silicate having pH of 10-12; 2-30 wt% of an aqueous acrylic emulsion including at least 40 wt% of nonvolatile matters; 0.1-5 wt% of an organic binder; 1-10 wt% of a water-repelling agent; 0.1-10 wt% of a preservative; and the remaining consisting of water. The potassium silicate has a molar ratio of SiO_2 to K_2O of 1:2.8 to 1:3.4, and includes 35-45 wt% of solid content. |
