01 Jan 1990TL;DR: In this paper, it is proposed that citric acid in the form of citrate ions are adsorbed on the plaster surfaces and retards the hydration, and the results show that it retards hydration.
Abstract: Hydration studies of commercial plaster of paris in presence of citric acid have been made by using temperature and electrical conductivity measurements. X-ray diffraction studies, Differential Scanning Calorimetry, Spectral studies and Compressive Strength measurements have also been made to understand the mechanism of hydration. Results show that citric acid retards the hydration. It is proposed that citric acid in the form of citrate ions are adsorbed on the plaster surfaces and retards the hydration.

TL;DR: In this paper, the results obtained by testing the PALIT equation 100ϱ0[η] + In M = K1M2/3 + K2 with solutions of some polyphosphates and copolyphosphate have been analyzed and compared with the MARK-HOUWINK relationship.
Abstract: The results obtained by testing the PALIT equation 100ϱ0[η] + In M = K1M2/3 + K2 with solutions of some polyphosphates and copolyphosphates have been analyzed and compared with the MARK-HOUWINK relationship. The values of the exponent a in the MARK-HOUWINK relationship were found to be higher for those samples which have higher values of K1 or lower values of K2 in the equation suggested by PALIT.
Die bei Anwendung der PALIT-Beziehung 100ϱ0[η] + In M = K1M2/3 + K2 auf Losungen einiger Polyphosphate und Copolyphosphate erhaltenen Ergebnisse wurden analysiert und mit der MARK-HOUWINK-Beziehung verglichen. Die Werte des Exponenten a in der MARK-HOUWINK-Beziehung sind fur die Proben groser, die grosere Werte K1 oder Kleinere Werte K2 in der von PALIT vorgeschlagenen Gleichung ergeben.
