    Ordinary Portland Cement 42.5 270
    High aluminum cement 60
    Sand 70-150 mesh 480
    Heavy Calcium Carbonate 400 mesh above 158
    Anhydrous gypsum 30
    Redispersible powder 12
    Cellulose ether MP400 0.8
    superplasticizer 3
    Lithium carbonate 0.5
    Defoamer 1
    Tartaric acid 1

    This recipe is not bad
    The proportion of cementitious material can be adjusted, the amount of Ordinary Portland Cement less, add more high-aluminum cement, if 60 kg of high-alumina cement, 24-hour strength and polished estimated more difficult.
    Gypsum is too small, I usually use 40 to 50 kg

    Superplasticizer is a special product, if it is 3kg polycarboxylic acid, then the quality of polycarboxylic acid is very poor, if the melamine type F10,3 kg amount is not enough.And Lithium carbonate is less
