Three gravity dams, each of 150-meter-high class with a concrete volume of 4, 700, 000 cubicmeters in all, were completed in the recent five years in Japan : 1, 122, 000 cu/m Sakuma Dam, 1, 949, 500 cu/m Tagokura Dam and 1, 627, 500 cu/m Okutadami Dam. Each of them was constructed of concrete quality different from each other : Sakuma Dam, of concrete using modified Portland cement exclusively, Okutadami Dam, of concrete using modified Portland cement but partly replaced by fly ash, and Tagokura Dam by using the two types ef concrete stated above in order to meet the structural requirement.
The actual states of control factors were grasped on the basis of the actual results of the quality control of this extraordinarily voluminous concrete. The author hopes that the conclusive statement based on this study as mentioned below will contribute in the future to the improvement of the manufacturing processes and the quality control of concrete.
