る。(Prior art) Concrete is made by kneading cement, aggregate, and water, but at this time, the heat of hydration of the cement (thus, the temperature rises.The increased temperature is caused by factors such as component dimensions and outside air temperature). Heat is dissipated and the temperature drops depending on the conditions. At this point, in mass concrete with large member dimensions, temperature cracks may occur due to the following mechanism.
■ 蓄熱され温度が高くなったコンクリート内部と冷却
された表面部との間の温度差に起因する温度応力（内部
拘束応力）によるもの。■ Temperature stress (internal restraint stress) caused by the temperature difference between the inside of the concrete, which has become hot due to heat accumulation, and the cooled surface.
■ 高温で硬化したコンクリートが冷却される過程で熱

力く外部拘束応力）によるもの。■ Heat shrinkage occurs during the cooling process of concrete that has hardened at high temperatures, and this is caused by temperature stress (external restraint stress) caused by being restrained from the outside.

定が必要となる。Therefore, in order to evaluate the PA characteristics of mortar and concrete that have the highest correlation with temperature cracking, it is necessary to be able to measure the temperature rise due to the heat of hydration reaction of cement under the same conditions as inside mass concrete. That is, it is necessary to measure the temperature rise value in an adiabatic state without heat transfer.

ンクリートの混練作業がモルタルやペーストに比較して
たいへんであるばかりか、装置が大きく高価であるため
、多くの試験槽を併列で設置できない。For concrete, not only is the work of mixing the concrete to prepare the sample much more difficult than that for mortar or paste, but the equipment is large and expensive, making it impossible to install many test chambers in parallel.
更に、コンクリート用のみであるため一回の測定に多量
のセメントを使用し、少量試料の評価に適さない欠点が
