抜粋

Strength and durability of concrete is important for using long-term structure. In order to obtain enough strength and durability, it is necessary to progress hydration on concrete during the early age. Therefore, it is important to monitor the hydration in the mold. However it is difficult to check the state of concrete in the mold. Then, we focused on the electrical resistance as a method to check hardening concrete for in the non-destructive test. It has been reported that the electric resistance of the hardening concrete has a correlation with compressive strength at remolding time and carbonation ratio. However, it is not measured in the fresh concrete. So, we measured the electrical resistance of fresh concrete in the mold. As a result, the behavior of the electric resistance is very similar to the results of heat of cement hydration measured by the conduction calorimeter. Moreover, the behavior of the electric resistance was correlated with the setting time. Thus, it can be monitored the hydration on concrete from fresh to harden in the mold by using the electrical resistance.
