The Improvement of the Precision of Temperature Control on the Precooling Method applied to Dam Concrete

Abstract

This paper focuses on the improvement of the precision of temperature control on the precooling method applied to dam concrete. Usually we control temperature of precooled dam concrete by evaluating the amount of precooling from the relation of the calorie earnings and expenses of concrete materials and measuring the placing temperature of precooled concrete.
We propose the control method of placing temperature of precooled dam concrete and verify its validity on Nakasujigawa Dam.
