| description | The invention discloses a method for preparing unfired ceramsite from casting ash, and relates to the technical field of ceramsite preparation methods, and the method comprises the following steps: uniformly mixing casting dust and fly ash to prepare a base material; uniformly mixing Portland cement, sodium hydroxide and calcium oxide to prepare an auxiliary material; mixing the water glass solution with water to prepare an adhesive solution; uniformly mixing the base material and the auxiliary materials to prepare a mixture, putting two thirds of the mixture into a disc granulator to serve as a base material, and then adding the rest mixture and the adhesive solution into the disc granulator in 3-5 times to prepare ceramsite green pellets; sieving the ceramsite green pellets; and aging the ceramsite green pellets indoors, carrying out steam oxidation in a water bath kettle, and then transferring into an electrothermal blowing dry box for drying to obtain the unfired ceramsite.
