Method of making concrete

A method of making concrete from substandard cement based on parameters provided for a corresponding standard cement, the parameters comprising a normal recommended amount of superplasticizer and a normal recommended amount of air detrainer, comprising:

• a) adding a superplasticizer to the substandard cement in a high shear mixer at a concrete wet mixing stage, where the superplasticizer comprises at least 125% of the normal recommended amount of superplasticizer with the standard cement;
• b) adding an air detrainer in the concrete wet mixing stage, the air detrainer comprising at least 140% of the normal recommended amount of air detrainer used with the standard cement;
• c) creating a cementitious material from steps a) and b);
• and
• d) deaerating the cementitious material during a discharge period of the cementitious material from the mixer via a vibrating thin layer reactor, the vibrating thin layer reactor forming a thin continuous layer of plastic cementitious material and temporarily reducing the viscosity of the plastic cementitious material in the vibrating thin layer reactor.
