The high strength concrete with the nominal strength of 36-39 which used natural gravel in Kyoto area was applied to the real structure. This paper was described about compressive strength, daily variation and quality control of concrete. Results are following. The coefficient of daily variation of compressive strength was about 6.5%, and the increase of strength was enough sufficiently. To measure a slump-flow and Slump-flow/Slump ratio as the evaluation of workability of fresh concrete was effective. For the detailed quality evaluation, the apparent density and coefficient of elasticity of specimen must be measured with the compressive strength.
