Research on Paste-Like Impregnation Coatings for Protecting Concrete

Abstract:

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. In this study, concrete was coated with paste-like emulsion impregnant. The factors that impact the waterproofing performance of the impregnant were investigated including the emulsifier amount, the penetration depth and the contact time. The capability of the impregnant was shown by the contact angle and the weight percent gain. The waterproofing performance of the concrete was increased after the coated with the so prepared impregnant.
