Influence of Hydrophobic additives on susceptibility to the formation of efflorescence on concrete elements

Ing. Radka Pernicová, Ph.D.

Influence of different type of hydrophobic additives on the concrete elements is presented in this paper. The aim of the article is experimental analysis of susceptibility to the formation of efflorescence depending on type of hydrophobic additive and its application. Hydrophobicity is obtained by coatings and internal additives. Measurement involves not only qualitative and quantitative efflorescence test but also determination of chemical composition of leaching salt crystals and also sorption properties. From the results obtained follows that the different kind of hydrophobic additive as well as type of its application have impact on the concrete surface properties
