Research on the Stability of the Paste-Like Silicone Impregnant

Article Preview

The protecting of concrete, which consists of coating a chemical substance onto concrete’s surface, has been applied to architectural conservation. There is increasing interest in studying materials for concrete which can reduce the infiltration of water and salt solutions and rehabilitate and extend its service life. Silicon compounds are frequently used as a base for commercial protecting paint due to their hydrophobicity and penetrability. However, the stability of the impregnant emulsion is affected by many factors. The effect of three main factors such as component, pH, and emulsifier were studied in this paper. The stability of the impregnant decreased with the increase of pH. And the mixed emulsifier and 4~6% amount of emulsifier would be optical for the stability of the system and maintain the activity at the same time.
