EFFECTS OF COMBINING SILICATE AND SILANE TYPE SURFACE PENETRANTS ON CONCRETE UNDER DIFFERENT WATER CONTENT CONDITIONS

摘要

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. Based on previous studies, when silicate and silane type penetrants were used in combination, good water interception and resistance to carbonation results were shown. In this paper, the effects of surface penetrants on the deterioration of concrete in new structures were analyzed in order to ascertain the practicality of utilizing such penetrants as well as to determine their performance under different water content conditions in concrete. The results revealed that the combined use of both surface penetrants showed better water interception than did either penetrant individually as well as offering a good resistance to carbonation which was similar to that for the silicate type alone.
