Zusammenfassung:To provide a method that can fixedly maintain temperature of a cement hardened body from start to end of a test and can accurately evaluate dynamic characteristics of the cement hardened body.SOLUTION: A testing method of dynamic characteristics of a cement hardened body includes steps of: determining a setting temperature at the time of heating by first heating means arranged via a space for a cement hardened body 6; determining a setting temperature at the time of heating by second heating means 9 arranged in contact with the cement hardened body; heating the cement hardened body at the setting temperature by using the first heating means; moving the heated cement hardened body to a place for testing dynamic characteristics; and measuring dynamic characteristics of the cement hardened body by using dynamic characteristic measurement means 12. The method maintains temperature of the cement hardened body at a target temperature or its neighborhood in the step of heating the cement hardened body at the setting temperature by using the second heating means and measuring the dynamic characteristics.SELECTED DRAWING: Figure 1 【課題】試験の開始から終了までセメント質硬化体の温度を一定に維持することができ、セメント質硬化体の力学的特性を正確に評価しうる方法を提供する。【解決手段】セメント質硬化体6に対して、空間を介して配設された第一の加熱手段の加熱時の設定温度を決定する工程と、セメント質硬化体と接触させて配設された第二の加熱手段9の加熱時の設定温度を決定する工程と、セメント質硬化体を、第一の加熱手段を用いて設定温度で加熱する工程と、加熱を終えたセメント質硬化体を、力学的特性を試験するための場所に移動させる工程と、力学的特性測定手段12を用いて、セメント質硬化体の力学的特性を測定する工程を含み、かつ、セメント質硬化体を、第二の加熱手段を用いて設定温度で加熱し、力学的特性を測定する工程において、セメント質硬化体の温度を、目標温度またはその近傍の温度に維持するセメント質硬化体の力学的特性の試験方法。【選択図】図1
