4. Summary

A mathematical model based mainly on the amount of elements (magnesium, sodium, calcium) in the mixture was presented in this paper. All previous factors, which were included in the further version of the model 22, were also included. The following conclusions can be drawn on the basis of the analysis and verification of the developed mathematical model:
