Investigation of Methods for Extraction,Detection,and Identification of Water-Soluble Admixtures in Concrete.

摘要

Methods for detecting, identifying, and quantitatively measuring carbohydrates and salts of hydroxylated carboxylic-acid admixtures in concrete were investigated. Two published methods for detecting sugar and an unpublished method for detecting both sugar and sodium gluconate were evaluated. Other methods investigated included: thin-layer chromatography, infrared spectroscopy, and high-pressure liquid chromatography.
