摘要
Abstract
This paper introduces the differential scanning calorimetry(DSC) incremental method which is used to determine magnesium hydroxide in cement paste added with magnesia and on this basis, proposes the once-incement method used to determine magnesium hydroxide also. Besides the paper evaluates the accuracy of these two methods by recovery rate. The result shows that the recovery rate of magnesium hydroxide in cement paste added with magnesia is more than 98.5％ by DSC incremental method and more than 97.5％ by once-incement method. Though the DSC incremental method has high accuracy in determination of magnesium hydroxide in cement paste added with magnesia and the once-incement method is slightly lower in accuracy, the once-incement method is superior to the DSC incremental method in simplified operation and can be used to determine magnesium hydroxide also.关键词
