STEEL CORROSION TESTS IN VARIOUS COVERINGS AND RELATIVE HUMIDITY : Corrosion of Structual Frames in Buildings of Steel Construction Part 2

Abstract

In order to confirm corrosion of structual frames in buildings of steel construction, corrosion tests of steel specimen in various coverings and relative humidity. Consequently, the following has been clarified. (1) In relative humidity over 70% steel corrosion has been started and in case of relative humidity over 80% it has been continuously. (2) If relative humidity in building has been kept less than 70%, steel in the building has no corrosion. (3) In general buildings, corrosion on structual frames of steel construction is no problem. So, anti-corrosive painting on the steel can be omitted.
