Аннотация
A procedure is developed for the determination of technical polymethylene naphthalene sulfonates (TPNS) in concrete by HPLC. The presence of 9.8–18.8% of a fraction with a low adsorption activity in TPNS is detected. A correlation is found between the initial slump of the concrete mix cone and the refined amount of oligomers of polymethylene naphthalene sulfonic acids with n ≥ 11, contained in TPNS.
