NOVELTY - A light waterproof concrete comprises polystyrene granule, fly ash, polyaluminum chloride, diatomite, wollastonite, silicon, marble waste residue, silicate cement, pebble, water, and auxiliary agent. The auxiliary agent comprises graphene oxide, aluminum silicate fiber, heptanoic acid diene propyl ester, acrylic acid dimethyl amino ethyl ester, coconut oil diethanolamine, methyl guaiacol, butyl methacrylate, 1,6 hexamethylene glycol diacrylate, trimethylolpropane acrylic ester, magnesium oxide, magnesium borate crystal whisker, safflower, sodium carbonate, and ammonium sulfate. USE - A light waterproof concrete. ADVANTAGE - The concrete is light, compact and waterproof. Through the use auxiliary agent, anti-folding strength resistance of concrete, fragrance, antirust property of concrete, and waterproof anti-seepage property are increased. The concrete has good reducing property, workability, plasticity and pumping effect. DETAILED DESCRIPTION - A light waterproof concrete comprises 20-25 pts. wt. polystyrene granule, 80-90 pts. wt. fly ash, 10-14 pts. wt. polyaluminum chloride, 20-28 pts. wt. diatomite, 100-120 pts. wt. wollastonite, 10-20 pts. wt. silicon, 170-190 pts. wt. marble waste residue, 160-180 pts. wt. silicate cement, 500-520 pts. wt. pebble, proper amount of water, and 25-30 pts. wt. auxiliary agent. The auxiliary agent comprises 0.5-0.8 pts. wt. graphene oxide, 6-7 pts. wt. aluminum silicate fiber, 1-1.3 pts. wt. heptanoic acid diene propyl ester, 1-2 pts. wt. acrylic acid dimethyl amino ethyl ester, 1-2 pts. wt. coconut oil diethanolamine, 0.4-0.6 pts. wt. methyl guaiacol, 2-3 pts. wt. butyl methacrylate, 1-2 pts. wt. 1,6 hexamethylene glycol diacrylate, 1-2 pts. wt. trimethylolpropane acrylic ester, 5-7 pts. wt. magnesium oxide, 2-3 pts. wt. magnesium borate crystal whisker, 0.4-0.5 pts. wt. safflower, 0.8-1.2 pts. wt. sodium carbonate, 0.1-0.2 pts. wt. ammonium sulfate, 0.1-0.2 pts. wt. potassium persulfate, and 16-20 pts. wt. water. Preparation method of auxiliary agent comprises mixing sodium carbonate, magnesium borate crystal whisker, coconut oil diamine, graphene oxide, aluminum silicate fiber, trifluoroacetic acid, heptanoic acid diene propyl ester, and acrylic acid dimethyl amino ethyl ester, grinding and dispersing for 10-15 minutes, and then adding water, heating to 70-80 degrees C, adding potassium persulfate, reacting for 20-30 minutes, then mixing other remaining components, heating to 80-90 degrees C, and reacting for 30-40 minutes to obtain the finished product. An INDEPENDENT CLAIM is included for light waterproof concrete preparation method comprising mixing the diatomite, polymerized aluminum chloride, polystyrene, and wood, grinding for 30-40 minutes, then mixing with water, uniformly stirring; uniformly mixing the marble waste residue, silicon hydroxyapatite powder, fly ash, silicate cement, and stone; uniformly mixing obtained mix slurry and other remaining component, stir reacting for 8-12 minutes, and then casting, vibrating, heating at 5-25 degrees C in a humid environment for 7-9 days to obtain the finished product.
