III
scope of application
· Suitable for wire rope mesh & mdash; Polymer mortar external layer structural engineering reinforcement

· It is applicable to all structures whose structures are easy to bend, especially on the slab and beam of reinforced concrete bridge, a representative bending structure of civil architecture

· It is applicable to the central part of the pier, the shaft of the main tower and the cracked part of the cement pavement of the expressway
It has the same system as the previous reinforced concrete structures

· Seismic reinforcement and reconstruction of reinforced concrete beams, columns, plates, walls and other structures

· When honeycomb, loophole, crack, protective layer damage, reinforcement leakage and other defects appear in the concrete, the surface repair works shall be carried out

· Thicken the protective layer, smooth the concave convex surface and repair the old concrete surface to improve the durability of the concrete

4、 Construction technology
· Base course treatment: the surface of the base course shall be flat, rough, clean, free of oil and floating ash, and free of sand, hollowing, cracks and other phenomena
Before construction, it shall be washed with high-pressure water gun and kept wet, but there shall be no ponding
When the interface is bonded, the interface treatment agent of high-strength polymer mortar can be applied in advance

· Hang up Drilling, positioning and fixing of wire mesh: the wire mesh end shall be adjusted according to the design requirements

· Material preparation: according to the mass ratio, the material is placed according to the weight ratio of the powder: =6: 1
Pour 90% of the emulsion into the mixing tank and add the powder for 1~2 minutes
Then pour the remaining 10% of the emulsion into the pot and stir it evenly
The prepared slurry shall be used up within 0
5 ~ 1 hour

· Application Workers: first, evenly spread the polymer mortar bottom coating on the surface of the moist concrete base (powder: emulsion weight ratio 3: 1), and apply polymer mortar on the side
High strength polymer
