<P>PROBLEM TO BE SOLVED: To provide a surface coating method and a surface heat treatment method contributing to reduction of a life cycle cost by protecting concrete structures from deterioration factors such as salt damage, frost damage, neutralization, alkali-aggregate reactions, or the like, on the basis of proper selection of a plurality of surface coating materials with durability for a long term and proper application of treatment methods, and by improving the durability with fine sight maintained by imparting water repellency or hydrophilicity to the surfaces. <P>SOLUTION: The surface coating method and the surface coating and heat treatment method apply a silicate-based inorganic modifier combined with an alkali metal ion source, or an inorganic coating agent with high performance principal ingredients of which are a silane-based permeable water-repellent agent and a polysilazane compound. <P>COPYRIGHT: (C)2013,JPO&INPIT |
