Industrial production of portland cement with the simultaneous introduction of hydrophobic components is simulated. Their effect on the properties of the modified portland cement is determined. The method developed provides insulation of the cement from drip and, partially, vaporous moisture. The interaction between the dispersed phase of the cement and molecules of the organic admixture takes place by forming hydrogen bonds between surface silanol groups of cement particles and oxygen-containing groups of the admixture. The industrial applicability of the hydrophobization method is shown.
