摘要
研究了回弹法和超声回弹综合法检测长龄期混凝土抗压强度的可靠性,建立了可以检测龄期几年到几十年的长龄期混凝土专用测强曲线,经过大量试件验证,证明其精度较高,符合CECS02-88《超声回弹综合法检测混凝土强度技术规程》对专用测强曲线的要求,在实际工程检测中有较好的应用效果。
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.
