| Abstract: | The reliability of the measurement of compressive strength of long-age concrete by combined ultra sonic-rebound method was studied. The special curves for the strength of long-age concrete were set up. Verification tests on many concrete examples showed the accuracy of the curves which agreed with the requirements of thestandard CECS02 - 88 and were effective for practical engineering testing. |
