Abstract
This study report is mentioned regarding the quality control of concrete used at Shintoyone Arch-Dam which was built by Electric Power Development Co. Ltd. on the Onyu, a tributary of the Tenryu River in Aichi prefecture.
In order to select the optimum mix proportion for arch dam, the specified mix was decided on the basis of the results obtained from tests of various mix proportion which combined aggregate, fly ash and some mixture agents.
In case of production control for concrete, the specifications keeping the umiformity of material quality in view point was strictly applied to control and check the quality of materials. And the concrete used these materials was producted under the control.
In the result of above mentioned, the quality of concrete was shown better than the specified one as follows ; 420kg/cm2 for average compression stress and 8% for coefficient of variation.
