Concrete defect repair construction

Concrete defect repair construction plan of concrete defect repair construction shall meet the following requirements: 1. Concrete surface defect repair process can be divided into basic level processing, construction and maintenance, repair mortar interface. 2. Basic level processing: defects of concrete area should make a mark, and then the edge cutting of appropriate along the repair a depth of not less than 10 mm. Excluding area has pollution or damage to the surface of the concrete and deep ditto; Repair area should be chisel edge of concrete processing, MAO to leak out of the surface of the concrete and steel bar for a thorough cleaning, chemical corrosion of early, should be used in high pressure water to wash, corrosion, and completely clear. 3 processing interface: polymer repair mortar before construction, bare steel should be fixed and rust resistance, bring after drying should use clear water concrete base thoroughly wetting, then spray or brush materials processing interface ( Concrete interface treatment beautiful seam an agent or concrete interface beautiful seam an agent) 。 4 polymer repair mortar construction: according to the force of the components, construction site and the site condition can be applied, mechanical spraying and adopt the die casting method for construction. 5 maintenance: polymer repair mortar after construction, appropriate maintenance.
