超声回弹法评定冻融混凝土的抗压强度
THE EXPERIMENTAL RESEARCH ON APPLYING REBOUND AND ULTRASONIC TO ASSESS COMPRESSIVE STRENGTH OF CONCRETE SUBJECTED TO FREEZE-THAW ACTION
【摘要】 笔者进行了大量的试验和分析表明:利用回弹法、超声法和回弹超声综合法评价冻害后混凝土的强度是一种简便而又行之有效的方法。本文利用试验结构拟和的专用测强曲线满足工程精度的要求。
【Abstract】 Many experimental results indicate that the method,which applies rebound and ultrasonic to assess compressive strength of concrete subjected to freeze-thaw action,is simple and effective.The special curve of assessing strength are obtained by test data,which meet the engineering required precision.
