| Abstract |
In the case of domestic, the strength presumption equation of ordinary strength's range proposed at Japan from which used materials and environmental condition differ has been used under the circumstance that systematic studies didn’t go on about strength presumption of high strength concrete. So the problems of credibility, etc have been occurred.
The purpose of this study is to evaluate the practical application to the construction field of strength presumption equation proposed by reviewing the strength of mock-up of high strength concrete using the equation after proposing the strength presumption equation of high strength concrete which is suitable for domestic situation.
The results are as follows ;
More the variables of the rebound number, ultrasonic pulse velocity, W/B, curing condition and age were added orderly, more the strength presumption degree was improved. Also in the case of the strength presumption equation by rebound number test, it is considered for the practical application to the construction field to be possible due to a little difference between real measure value and presumption value. |
