Abstract
The purpose of this paper is to clarify persistence of the surface protection effects environment in outdoor exposure and suppress degradation of the penetrant by increasing the reactivity of the Alkoxy group in the pores of the concrete. Here, we report the results of evaluation based on the JSCE-K571-2004 by using the two different types of Silane. It was found that: 1) Performance of Silane has been improved surface protection effects by increasing the reactivity than the depth of penetration. 2) Surface protection effects of concrete were significantly improved by combining the Silane and Silane-Siloxane. 3) The effectiveness of reforming the surface properties of concrete was confirmed that surface protection effects has been maintained Even after 48 weeks of outdoor exposure.
