The effectiveness of additives
The following are excerpts from scientific and technical Scientific Technical Report published in 2012. On the basis of this data it is possible to receive general idea about properties of the additive, however these properties can essentially change depending on structure of concrete, properties of cement and filling materials.
In all trials following structures were used:

The analysis of increase of frost resistance and water tightness
At frost resistance and water tightness research the additive structure which was used for research of water reducing properties of the additive has been used.
