수경성 무기재료의 수화도 측정에 대한 건조방법의 영향: 2) 알칼리 활성 슬래그 = Influence of Drying Methods on Measurement of Hydration Degree of Hydraulic Inorganic Materials: 2) Alkali-activated slag

다국어 초록 (Multilingual Abstract)

The present study was carried out to find a suitable drying method for the determination of non-evaporable water in hydraulic inorganic materials. In Part 1 of the paper, the case ordinary Portland cement was discussed and, in this Part 2, the case of alkali active slag (AAS) was investigated. Various drying methods including vacuum and oven drying, and an ignition, were used for the AAS system having different w/b, types and amounts of alkali activators. It was found that a combination of the vacuum and oven drying was a suitable drying method for the AAS case. Although a part of the crystallized water in hydration products was decomposed, but the free and adsorbed water could be completely evaporated and the deviation of the results was small.
