ABSTRACT
The effects of surface penetrants on the deterioration of concrete vary widely based on the types of materials and the conditions under which they are used. Silicate- and silane-type penetrants are currently two of the most frequently used such materials. Here, the authors examine an application method of combining silicate- and silane-type surface penetrants, and aim at clarifying the effects of surface penetrants. In this paper, in order to ascertain the difference in the major component of silicate and silane, two kinds of silicate-type and three kinds of silane-type surface penetrants were used. The standard interval time in the application of surface penetrant was set at 24 hours. The results revealed that a combination type showed sufficient water interception qualities in any combination and also offered resistance to chloride ion penetration.
