Anti-cracking concrete additive and production method thereof
The invention discloses an anti-cracking concrete additive and a production method thereof. Comprising the following raw materials in parts by weight: 20-30 parts of mica powder, 5-10 parts of silicon carbide whiskers, 4-15 parts of modified steel fibers, 5-10 parts of graphene oxide aerogel, 5-10 parts of calcium gluconate, 5-15 parts of metakaolin, 5-10 parts of sodium dodecyl benzene sulfonate, 5-10 parts of microcrystalline cellulose, 20-25 parts of a porous nano modified material mixture and 10-15 parts of a hybrid NA-BTC nano porous material. The coating is prepared from the following components in parts by weight: 2-5 parts of an air entraining agent, 2-5 parts of an anti-freezing agent, 2-5 parts of a water reducing agent, 2-5 parts of a retarder, 2-5 parts of a corrosion inhibitor, 2-5 parts of activated carbon, 2-5 parts of vinylon fibers, 10 parts of SiO2, 23 parts of benzidine, 2 parts of anhydrous THF, 10 parts of trihydroxy-s-tribenzaldehyde, 1.5 parts of n-butyl alcohol, 7.5 parts of orthodichlorobenzene and 90k liquid nitrogen. According to the anti-cracking concrete additive and the production method thereof, the breaking strength and toughness of concrete are improved, the crack width is limited, concrete surface cracking is resisted, the anti-cracking concrete additive has excellent compressive strength, anti-cracking performance and anti-seepage performance, has high hydrophilicity, and the fluidity of cement is improved.
