Base disposal of color wear-resistant concrete aerial construction: it is to clean the base surface before construction, so that the working face can be fully exposed; it is to investigate the basic situation and stop comprehensive and meticulous inspection of the working face through on-site testing tools, and make detailed records. The aerial construction is a shade project, so the base surface situation must be clearly investigated and well recorded (can be synthesized into multiple maps). Paper), the size of the base surface should be marked separately on the drawings (accurate to centimeters); it is grinding and dust-collecting that the old base surface with unsatisfactory smoothness should be partially grinded and integrated grinding to stop the thorough grinding and dust-collecting; it is the disposal of the defects of the base surface (shelling, cracks, notches); the shelling is the separation surface of concrete and mortar peeled off, without good adhesion (if the whole score). If the surface is peeled off, the mortar should be cleaned up and repaired by resin grouting if only a part of the surface is peeled off. The crack is often repaired by resin grouting. When the crack is repaired by raising the shell, the U-shaped groove with a width of about 1 centimeter is cut along the crack and filled with resin mortar. The crack is the state of local occurrence of grooves at the basic level (disposal method). It is to clean the dust and other dirty materials and smooth them with resin mortar: wear-resistant epoxy flooring main materials and curing agent are proportionally matched (refer to the manufacturer's product specifications), mixing with portable electric mixer and pouring the mixed primer into the air on the clean base level on average, and applying the primer with rubber scraper or roller.
