Effect of Modified Hydrophobic Additives on Properties of Cement Mortars and Concretes
For volumetric hydrophobization of cement stone it was proposed to use organosilicon hydrophobic additives GKZ- 11N and GKZ-94M adsorbed on surface of minerals (microcalcite, microsilica), and coating with a layer of lated agent - road asphalt. It was demonstrated that this method ensured time regulated input of hydrophobic additive into hardening cement. Such hydrophobic additives do not slow hydration and hardening of mortars and concretes , but they contribute to higher water and corrosion resistance
