         The course Non-destructive Testing of Concrete addresses four prevalent quality issues in engineering: concrete strength, concrete defects, reinforcement in concrete and the integrity of concrete foundation piles. It also covers ten commonly used on-site quality inspection techniques: the rebound method, ultrasonic-rebound combined method and drilled core method for testing concrete strength, the ultrasonic method for measuring concrete crack depth, the ultrasonic method for detecting uncompacted areas and pores in concrete, the ultrasonic method for assessing concrete interface quality, the electromagnetic induction method for determining reinforcement diameter, spacing, and concrete cover thickness, the half-cell potential method for evaluating reinforcement corrosion condition, the crosshole sonic logging (CSL) method and low strain method for assessing engineering pile integrity. The course primarily delves into the various inspection techniques commonly used to address issues related to on-site engineering quality. This involves the utilization of main instruments, and the development and application of new technologies, materials and processes in engineering inspection. It is specifically designed to develop higher vocational students' proficiency in on-site engineering inspection techniques, data processing and test report preparation. Its aim is to instill proper values, foster excellent professional habits, and nurture highly skilled technical personnel capable of serving in roles such as inspectors, testers, and quality controllers.
