AbstractAbout AuthorsReferences
It is well known, that the efficiency of hydrophobic admixtures drastically depends on chemistry, dispersity and concentration of containing ingredients. This study reports on the effect of different factors on hydrophobic characteristics of polymethylhydrosiloxane (PMHS) containing water-based emulsions applied as a coating for concrete wearing surfaces. Calculations of topological characteristics proved the effectiveness of mineral additives such as silica fume and metakaolin in the formulation of hydrophobic siloxane emulsions, in terms of their physical-and-chemical potential. It was demonstrated that the emulsions produced with 1% of mineral nano- and micro-sized particles (silica fume/metakaolin) showed a high stability of emulsions and required workability when applied to concrete surfaces..
