QUALITATIVE/QUANTITATIVE ANALYZING METHOD OF GRINDING AID IN CEMENT AND QUANTITATIVE ANALYZING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a qualitative/quantitative analyzing method which enables the accurate quantification of a grinding aid in cement while accurately performing the qualitative analysis of the grinding aid in cement. PSOLUTION: The qualitative analyzing method of the grinding aid ex1 in cement (c) includes a heating desorption process ST1 for extracting extracts ex1 and ex2 along with other components without pyrolyzing the grinding aid ex1 by performing heat desorption treatment with respect to the cement (c) containing the grinding aid ex1, a gas chromatography process ST3 for respectively detecting the extracts ex1 and ex2 in a recognizable state, a mass analyzation process ST4 for respectively measuring the mass spectra of the detected extracts ex1 and ex2 and a qualitative analyzation process ST5 for identifying the grinding aid ex1 from the masses of the extracts ex1 and ex2 and further includes a quantitative analyzing process ST6 for measuring the amount of the identified grinding aid ex1.
