The article describes the features of the influence of paraffin emulsions, which contain nano-sized particles, on fastness to water of gypsum binders of β-modification. The results of these studies show the effectiveness of paraffin emulsions “EMVAKS-GIPS-1” and “EMVAKS-GIPS-2”, containing nano-sized particles, to improve the fastness to water of products made of gypsum binders of β-modification – softening factor increased from 0.35 to 0.52–0.72. It is established that the main criterion of the effectiveness of paraffin emulsions gyp- sum binders of β-modification is the size of individual paraffin particles – a significant increase in efficiency is achieved when used with the paraffin emulsion particles less than 2 mkm, including nano-sized particles of less than 300 nm. Determined the features of structure of gypsum binders with introduced paraffin emulsions with different particle sizes.
