(1) preparing quartz sand powder: firstly, preliminarily crushing a quartz stone raw material into coarse materials, then further crushing and screening by using a vibrating screen to obtain quartz sand powder of 40-70 meshes;
(2) preparing ash calcium powder: adding 20-30 parts of water into a water pool, dissolving 3-5 parts of aluminum potassium sulfate in the water, uniformly stirring, pouring 15-20 parts of quicklime into the water pool, uniformly stirring, standing for 24-36 hours to obtain lime paste, taking out, naturally airing until the water content is 15% -20%, and crushing the dry lime paste to the fineness of 200-300 meshes to obtain lime powder;
(3) preparing seaweed gel: taking fresh seaweed, washing the seaweed by using clear water, cutting the seaweed into blocks with the length of 1-3 cm, then putting the seaweed into hot water with the temperature of 80-90 ℃ for scalding for 1-3 minutes, taking the seaweed out, cooling the seaweed to room temperature, putting the seaweed into a pulping machine, and adding distilled water and an ethanol water solution with the weight percentage concentration of 75-85%, wherein the seaweed: distilled water: the weight ratio of the ethanol water solution is 1: 2: stirring and pulping for 5-10 minutes to prepare seaweed slurry, filtering to remove solid impurities to obtain seaweed gel liquid, and performing spray drying on the seaweed gel liquid to obtain seaweed gel powder;
(4) preparing a mortar coarse material: taking common cement, fly ash, ash calcium powder and quartz sand powder, stirring and mixing uniformly, then adding polypropylene fiber with the length less than 1 mm, and then continuously stirring by using a high-speed double-shaft stirrer to uniformly mix the fibers to obtain a dry-mixed mortar coarse material;
(5) and (3) preparing a finished product: firstly, mixing and stirring the dry-mixed mortar coarse material prepared in the step (4) and seaweed gel powder for 5-10 minutes until the dry-mixed mortar coarse material and the seaweed gel powder are uniformly mixed, then sequentially adding the redispersible latex powder, the mortar reinforcing agent and the wood or hair fibers, continuously mixing and stirring for 5-10 minutes until the materials are uniformly mixed to obtain a raw material, then adding the talcum powder or/and the scallop shell powder into the uniformly mixed raw material, mixing and stirring for 10-15 minutes until the materials are completely and uniformly mixed, and then sealing and packaging to obtain a high-strength concrete slurry finished product; during construction, water is added and blended to be used for surface treatment of the outer wall of a building; the mortar has the performances of light reflection, heat preservation, water vapor permeability, strong adhesive force and the like, and the addition of the sierozem powder is beneficial to the drying speed of the mortar after construction and the reduction of the specific gravity of the mortar.
2. The surface property-adjustable high-strength concrete slurry according to claim 1, wherein: the related scallop shell powder is obtained by firstly washing scallop shells with meat quality and algae removed in baking soda water solution with the weight percentage concentration of 3-5% twice, naturally drying, and then crushing into powder of 100-200 meshes.
