Abstract


A set of different measurements including inorganic anions simultaneously in presence of chloride is conducted on cement-like CaCO3 whereupon competitive adsorption measurements are correlated to zetapotential measurements. The adsorption isotherm of chloride on is obtained and the amount of bound and free chloride is investigated. Mild and stainless steel coupons are exposed to the supernatant solutions after centrifugation of the limestone suspensions and corrosion rates are calculated. The study gives an insight on the role of salinity and pH and the correlation of bound to free chlorides on the corrosion rates of steel in pipes in oil well cementing
