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
