Title: Determination of Calcium Sulfoaluminate in Cement Paste by Tracer Technique
Author(s): Toshio Manabe and Naoya Kawada
Publication: Journal Proceedings
Appears on pages(s): 639-650
Abstract:To determine the rate of combination of gypsum with aluminate phases during the first few minutes of initial hydration period, a method using radioactive isotope sulfur-35 as a tracer was studied. The method consists of a combination of Forsen’s extraction method with an isotope dilution method. Procedures are described and results discussed. From these results some considerations regarding the initial hydration process of Portland cement are presented.
