Comparison of Concrete Strength Testing Methods and Research on Qualification Evaluation System

With the rapid development of the economy, the scale and quantity of construction projects in China are expanding rapidly. As new construction projects increase and are completed rapidly, accurate and efficient detection of the construction quality of building structures becomes crucial. Various non-destructive and micro-damage testing methods have been developed and are widely used in practical engineering. This article combines practical engineering projects and test results to explore the relationship among different concrete strength testing methods: the rebound method, core drilling method, and standard test blocks cured under both same and standard conditions. It also explores the determination of the qualification threshold for physical testing evaluation, based on relevant specifications and case studies, providing comprehensive practical experience and theoretical reference for the detection of solid concrete specimens.
