INVESTIGATION OF CONCRETE IN THE FORMER OGIMI VILLAGE OFFICE BUILDING CONSTRUCTED WITH BLAST FURNACE CEMENT CLASS C

Abstract

A 99-year-old reinforced concrete building, formerly serving as the Ogimi Village Office and constructed with concrete equivalent to blast furnace cement Class C, was investigated. Despite being located in a salt-affected environment with high levels of airborne salt, EMPA analysis confirmed that the permeation of chloride ions into the building was suppressed.
