Corrosion Inhibitors for Steel in Concrete - Concrete Service

WebCorrosion inhibitors are classified as anodic, cathodic or mixed inhibitors depending on their mechanism of action, inorganic and organic inhibitors according to their chemical structures,... Web(e.g. hydrophobation) or by admixtures that reduce porosity of the concrete (e.g. fly ash, silica fume, waterproofing admixtures etc.) are not considered to be corrosion inhibitors. Most of the results published in literature and reviewed recently [4 – 6] are from laboratory studies using solution experiments or relatively small mortar samples. noteability安卓
