NOVELTY - Rapid hardening high strength concrete comprises 8-11 pts. wt. lithium carbonate, 7-9 pts. wt. lithium oxide, 20-24 pts. wt. lithium bentonite, 20-24 pts. wt. calcined kaolin, 20-25 pts. wt. bisphenol A epoxy resin, 50-70 pts. wt. silica powder, 6-8 pts. wt. zinc phosphate, 350-380 pts. wt. sand, 170-190 pts. wt. cement, 560-590 pts. wt. gravel, 25-30 pts. wt. additive and proper amount of water. The additive includes graphene oxide, aluminum silicate fiber, trifluoroacetic acid, allyl enanthate, dimethylaminoethyl acrylate, cocoyl diethanolamide, and methyl guaiacol. USE - Rapid hardening high strength concrete. ADVANTAGE - The concrete has high coagulating speed and high intensity. The addition of bisphenol A epoxy resin and silica powder results in good water resisting property and high intensity. The use of additive increases the anti-folding strength resistance of concrete, increases the fragrance, and improves the anti-rust property, waterproof anti-seepage property, water reduction property, workability, plasticity and pumping effect. DETAILED DESCRIPTION - Rapid hardening high strength concrete comprises 8-11 pts. wt. lithium carbonate, 7-9 pts. wt. lithium oxide, 20-24 pts. wt. lithium bentonite, 20-24 pts. wt. calcined kaolin, 20-25 pts. wt. bisphenol A epoxy resin, 50-70 pts. wt. silica powder, 6-8 pts. wt. zinc phosphate, 350-380 pts. wt. sand, 170-190 pts. wt. cement, 560-590 pts. wt. gravel, 25-30 pts. wt. additive and proper amount of water. The additive comprises 0.5-0.8 pts. wt. graphene oxide, 6-7 pts. wt. aluminum silicate fiber, 1-1.3 pts. wt. trifluoroacetic acid, 1-2 pts. wt. allyl enanthate, 1-2 pts. wt. dimethylaminoethyl acrylate, 0.2-0.3 pts. wt. cocoyl diethanolamide, 0.4-6 pts. wt. methyl guaiacol, 2-3 pts. wt. butyl methacrylate, 1-2 pts. wt. 1,6-hexanediol diacrylate, 1-2 pts. wt. trimethylolpropane triacrylate, 5-7 pts. wt. magnesium oxide, 2-3 pts. wt. magnesium borate crystal whisker, 0.4-5 pts. wt. safflower, 0.1.8-1.0 sodium carbonate, 0.1-0.2 pts. wt. ammonium sulfate, 0.1-0.2 pts. wt. potassium persulfate, and 16-20 pts. wt. water. The concrete is prepared by mixing sodium carbonate, magnesium borate crystal whisker, cocoyl diethanolamide, graphene oxide, aluminum silicate fiber, trifluoroacetic acid, allyl enanthate and dimethylaminoethyl acrylate, grinding and dispersing for 10-15 minutes, adding water, heating to 70-80 degrees C, adding potassium persulfate, stirring and reacting for 20-30 minutes, mixing, heating to 80-90 degrees C, adding other residual components, stirring and reacting for 30-40 minutes to obtain the finished product.
