Embodiment 1
[0025] A method for preparing a building board mixed with composite minerals, characterized in that:
[0026] Weigh raw materials: cement 282g, cement composite mineral additive 18g, sand 750g, polypropylene fiber 4g, naphthalene-based water reducer 3g; put the above raw materials into a conical double-helix mixer and stir evenly for 50 minutes. After stirring Casting into the mold; static curing, the time is 8 hours; after static curing, enter the autoclave for the first autoclaving curing, the temperature of the first autoclaving curing is 220 ° C, and the time is 10 hours; after that Cool naturally, place at room temperature for 4 hours, and perform the second autoclaving curing, the temperature of the second autoclaving curing is 160° C., and the time is 20 hours; a building board mixed with composite minerals is obtained.
