Impact of Hot Cement on the Concrete Mix

Initial studies by Lerch 1955 see reference below and duplicated research has shown that to lower the temperature to normal concrete by 1 degree Celcius the temperature of the cement must be reduced by degrees Celcius the temperature of the water reduced by degrees Celcius and the temperature of the aggregates lowered only

Cement mill Wikipedia

In addition to fineness added materials in the cement must be controlled In the case of gypsum addition the material used is frequently of variable quality and it is normal practise to measure the sulfate content of the cement regularly typically by x ray fluorescence using the results to adjust the gypsum feed rate
