Analysis of triethanolamine in white cement pastes by voltammetric methods

Abstract

Triethanolamine (TEA) in cement paste has been analysed by square wave voltammetric technique. The technique is sensitive for the quantitative determination of small amounts of TEA. The percentage of the adsorbed TEA is very dependent upon the original TEA content of the cement sample. The adsorption reached a saturation level after 12 hours of hydration and remained almost invariant at longer times. (C) 1999 Elsevier Science Ltd. All rights reserved.
