Novel rapid concrete surface repairing agent and construction method

Abstract

The invention discloses a novel rapid concrete surface repairing agent. The novel rapid concrete surface repairing agent contains the following substances in parts by mass: 75-85 parts of acrylic, 2-8 parts of water repellent, 5-10 parts of thickener, 5-10 parts of viscosity agent, 2-6 parts of stabilizer, 5-15 parts of water reducing agent, 5-10 parts of cosolvent, 10-15 parts of penetrant, 5-15 parts of antifoamer, 2-4 parts of curing agent and 10-15 parts of toner. The invention further discloses a preparation method and a construction method. According to the novel rapid concrete surface repairing agent and the preparation and construction methods, the novel rapid concrete surface repairing agent can be used for enhancing the aesthetic property of central separating belts, fender walls and the like, repairing cracks and spots of repaired surfaces, repairing micro-crack and reticular-crack parts, beautifying appearance of ceilings and preventing neutralization and deterioration; the novel rapid concrete surface repairing agent is integrated with the former concrete color, is high in adhesion, is free of disengagement and discoloration phenomena, has a waterproof layer effect, can be used for carrying out sealant treatment on the micro-crack parts and is used for preventing deterioration and chemical corrosion; and the novel rapid concrete surface repairing agent has excellent adhesion and is high in adhesive power after the novel rapid concrete surface repairing agent is mixed with concrete, and the novel rapid concrete surface repairing agent is a cationic emulsion product.

Description

technical field [0001] The invention belongs to the technical field of highway maintenance, and in particular relates to a novel concrete rapid surface repair agent and a construction method. Background technique [0002] Concrete pavement, protective wall, ground, central separation zone and other parts, due to the long-term effects of natural conditions such as rainwater corrosion, exposure to the sun, weathering, or long-term overload load, such as the road surface being rolled by heavy vehicles, or Cracks, peeling, peeling, pits and other diseases often occur due to reasons such as material selection of concrete materials, unreasonable proportioning design, and poor technical performance. The early disease is generally not obvious, but as time goes by, the disease gradually becomes serious, which is likely to cause accidents and even cause major economic losses. In addition, the above diseases will seriously affect the aesthetics of the concrete surface, so a surface re...
