This study is to investigate experimentally the effect of the use of crushed lime stones coarse aggregate on the engineering properties of the high strength concrete. The results are summarized as follows. Slump flow according to change in substitutional ratio of limestone coarse aggregate is shown to be increased. On the other hand, reaching time to 500 mm according to change in substitutional ratio of limestone coarse aggregate had shown a favorable result of 24~30 seconds, and as age increases, the compressive strength also increases.
