Measurements of Blast Furnace Slag Reaction Degree in Cement Paste
摘要
Abstract
The reaction degree of ground granulated blast furnace slag in 1-360 d cement based paste was determined by selective chemical dissolution(CRS)and backscattered image analysis(BSE-IA) respectively and the measurement error was analyzed.Then, the accuracy of two measurements was compared by comprehensive analysis and the reasons of testing errors were analyzed.The results show that the values of slag reaction degree determined by CRS is lower than that determined by BSE-IA significantly for the same sample during the whole test age.The test value of CRS is lower than truth value because of inadequate dissolution while the test value of BSE-IA is higher than truth value because of granular edge effect and filtration treatment of image.Test values of slag reaction degree determined by BSE-IA has better consistency with the results of compressive strength test and microscopic image analysis than that determined by CRS, which shows BSE-IA is more accurate than CRS in quantitative determination of slag reaction degree in cement based paste.关键词
