Problems solved by technology

[0002] Concrete is usually used in the laying of traffic road bridge decks and building construction, but the setting time of concrete is slow and the maintenance cost is high. In addition, it is easy to crack, difficult to lay, weak in bonding and not durable in areas with severe cold and corrosion. , cumbersome process and other problems, how to adapt to the construction in severe cold environment with high quality and ensure the quality of laying is the problem to be solved by the present invention

Embodiment

[0014] Example: A high-performance polymer repair mortar, the high-performance polymer repair mortar is composed of the following raw materials by weight percentage: 35 parts of double fast anti-cracking aluminum sulphur cement, 5 parts of cement, 0.15 parts of polybasic acid, Wake 2.5 parts of rubber powder, 0.1 part of cellulose mud, 0.25 parts of lithium carbonate accelerator, 0.3 parts of silicon-magnesium lubricant, 0.07 parts of sodium citrate, 40 parts of water-washed sand, and 16.63 parts of quartz sand.

[0015] When in use: Add water to the mixing machine and add the repair mortar while stirring and continue to stir for 5 minutes. The weight ratio of water: repair mortar is 1:10. Clean the surface of the building substrate, keep it clean and free of impurities, and soak the building with water Apply the mixed repair mortar to the surface of the building substrate evenly with a trowel.

Abstract

The invention discloses high-performance polymer repair mortar which is prepared from the following raw materials in weight percent: 34 to 36% of dual-quick anti-cracking sulfur-aluminum cement, 4 to6% of cement, 0.14 to 0.16% of poly element acid, 2.4 to 2.6% of wacker rubber powder, 0.09 to 0.11% of cellulose mud, 0.24 to 0.26% of lithium carbonate coagulant, 0.29 to 0.31% of silicon-magnesiumlubricant, 0.06 to 0.08% of sodium citrate, 39 to 41% of washed-out sand and the balance of quartz sand. The prepared repair mortar disclosed by the invention has the advantages of good construction workability, strong binding force with concrete members, no drooping in trowel wiping, wide application to flat surfaces, vertical surfaces and top surfaces of the concrete members, no crack after being hardened, no shrinkage, high strength, very good frost thawing resistance, salt frost resistance, fluorinion permeability resistance and durability.

Description

Technical field [0001] The invention belongs to the field of construction engineering materials, and specifically relates to a high-performance polymer repair mortar. Background technique [0002] In traffic road bridge deck paving and building construction, concrete is usually used for work, but the concrete setting time is slow, the maintenance cost is high, and in severe cold and corrosive areas, it is easy to crack, difficult to lay, weak in bonding, and not durable. , The process is cumbersome and other problems, how to adapt to the severe cold environment construction easily, quickly and with high quality and ensure the laying quality is the problem to be solved by the present invention. Summary of the invention [0003] In order to overcome the shortcomings of the prior art and realize the above requirements, the present invention provides a high-performance polymer repair mortar suitable for laying and repairing concrete components in severe cold areas and not easy to cra...
