High-performance polymer repair mortar

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...
