Abstract
The problem of migration of ammonia in the air of residential and public buildings from reinforced concrete products during exploitation is discussed in the article. The different methods of determining the ammonium ions in aqueous solutions are reviewed by the authors. The data of potentiometric and spectrophotometric determination of ammonium ions in concrete admixtures, as well as within the concrete samples are presented in the article. A method for the preparation of concrete samples for chemical analysis is proposed. It is shown that the potentiometric method can be the basis of express-method for the determination of ammonia. It is assumed that the concrete modifiers can be probable sources of emission of ammonia from concrete as a final product.
