CORROSION PREVENTION METHOD OF EXPOSED STEEL MATERIAL IN RC OR SRC STRUCTURE AND PLACING JOINT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a corrosion prevention method of exposed steel materials and a placing joint method capable of eliminating removing work such as anticorrosives applied to the surfaces of steel, reinforcing bar, etc., or chipping of covered concrete/scraping, etc., and having no worry about the lowering of strength in the placing joint, vibration/noise and waste disposal. ;SOLUTION: Polymer cement 4 is applied to the surfaces of an exposed beam-steel 1 and beam reinforcing bars 2 to coat as corrosion-proofing. As the polymer cement 4, for example, Nihon Kasei's NS BOND SUPER composed of miscible liquid having a specifically modified ethylene vinyl acetate copolymer emulsion as main ingredients and mixing powder of normal Portland cement, natural hard aggregate, thickener, water reducing agent, etc., is used.;COPYRIGHT: (C)1998,JPO
