混凝土强度的无损检测是在不影响混凝土结构物或构件完整性的前提下进行的.目前采用的主要方法有回弹法、超声法、敲击法及其综合方法.现在已逐步广泛采用.根据湖南省的情况,采用了回弹法和超声法,以及两者的综合方法,来制定混凝土强度基准曲线,以判断混凝土的强度,作为混凝土工程质量验收、事故工程的分析处理的一种手段.在检测中如何对测试数据进行处理,将是最为关心的问题.本文将简单介绍对测得混凝土强度(R)、声速(V)和回弹值(N)数据,如何进行分析、计算、以及采用电子计算机进行数据处理等.
Non-destructive testing of concrete strength is carried out without affecting the integrity of concrete structures or components. Currently, the main methods used are rebound method, ultrasonic method, percussive method and its comprehensive method. Now it has been gradually widely used. In Hunan Province, the rebound method and ultrasonic method and the combination of the two methods are used to formulate the concrete strength reference curve to determine the strength of the concrete as a measure of the quality acceptance of concrete works and the accident engineering analysis and treatment. How to process the test data in the test will be the most concerned issue. This article will briefly introduce how to analyze, calculate, and calculate the concrete strength (R), sound velocity (V) and rebound value (N) data. Using electronic computers for data processing.
