The developed hydrophobic complex protective layer based on polymethylhydrosiloxane (PMHS) organosilicons on the top layer of the concrete surface along with hydrophobic characteristics and low ice adhesion strength enable to provide a developed surface roughness that is a direct measure of high traction forces between vehicle tires and road surface pavement, and its applicability in transport infrastructure as one of the inti-icing methods.
Portland cement mortar samples treated with PMHS-based hydrophobic emulsion demonstrated very apparent hydrophobic and icephobic characteristics. The majority of the coated mortar samples reveal over- and superhydrophobicity.
Ice adhesion of the mortars with hydrophobic coatings was 10 times lower in comparison with the reference non-treated hydrophilic samples.
