METHOD FOR REPAIRING AND RESTORING SURFACE DEFECT OF CONCRETE STRUCTURE

摘要

Let's face the present invention is that the concrete is cured almost immediately after stripping the formwork (aggregate separation, bubbles, peeling, exfoliation, surface contamination, damage, etc.) and concrete deterioration caused by a long period of time has elapsed after casting, surface peeling due to environmental factors, exfoliation, pollution, which can repair or restore the original properties of concrete carbonation of concrete surfaces The aim is to provide a plurality Let's face restoration method. ; Let's face of concrete repair restoration method according to the present invention to achieve this is with the cleanup phase (S1) to clean up the gritty, uncluttered surfaces the first special cement and plaster step (S2) for plastering mortar, and plaster surface planarization step of planarizing the primary special cement mortar cured (S3) and, on a flattened side in the liquid phase to the raw cotton and color and texture integrally secondary and ppumchil step (S4) for bonding by spraying a special cement mortar, after ppumchil secondary curing of special cement mortar, including a pattern coloring step (S5) to color the specific pattern is characterized in that the concrete is made.
