Non-Destructive Testing and Instrumentation in a Concrete Lab

该项目的重点是通过加强混凝土实验室以增加无损检测(NDT)和仪器的新模块来提高本科生混凝土教育的质量。混凝土是佛罗里达州大多数建筑项目的首选材料，学生们也经常选择混凝土课程，而不是类似的钢材设计课程。然而，如果没有完整的实验室和现场经验，学生们就不能充分理解混凝土等异质材料的设计和施工的各个方面。随着国家基础设施日益恶化，将无损检测技术和现场仪表纳入土木工程课程的必要性比以往任何时候都更加明显。UCF的本科课程包括两门3学分的具体课程：Reinf。混凝土。结构，和Conr.设计，第二门课程侧重于实际的设计项目。开发了一个为期两个学期的实验室，以便在这些课程中并行授课。实验室实验将包括拔出测试、回弹方法、探头技术、绘制混凝土中钢筋的粘结强度图、测量钢筋的腐蚀活性、检测混凝土中各种形式的缺陷、谐振频率法、脉冲雷达技术、超声波方法、成熟度函数、声发射和混凝土构件的仪器。人们相信，新的实验室将显著提高学生对具体课程的兴趣，并从中学习。每年大约有100名学生有机会在动手实验室和现场体验中学习最先进的混凝土无损检测和仪器技术。UCF在无损检测研究方面有着良好的记录，拟议的改进将允许将知识传授给本科生。UCF承诺提供：(1)100%配套资金用于购置设备，(2)继续支持定期升级和维护设备，以及(3)指派专业技术人员负责购置的设备。

The focus of this project is to improve the quality of undergraduate concrete education by enhancing the concrete laboratory to include new modules for Non-Destructive Testing (NDT) and Instrumentation. Concrete is the material of choice for most construction projects in Florida, and students too, often choose concrete courses over similar steel design courses. However, without a complete laboratory and field experience, students can not fully appreciate various aspects of design and construction with a heterogeneous material such as concrete. With the growing state of deterioration of the nation's infrastructure, the necessity for including NDT techniques and field instrumentation in civil engineering curriculum has become more apparent than ever before. The undergraduate program at UCF includes two 3-credit concrete courses; Reinf. Concr. Struct., and Concr. Design, with the second course emphasizing on an actual design project. A two-semester laboratory is developed to parallel the lectures within these courses. The laboratory experiments will include pull-out tests, rebound methods, probe techniques, bond strength mapping reinforcement topology in concrete, measurement of corrosion activity in reinforcement, detection of various forms of flaws in concrete, resonant frequency method, impulse radar technique, ultrasonic methods, maturity functions, acoustic emission, and instrumentation of concrete members. It is believed that the new laboratory will significantly increase student's interest in, and learning from, the concrete coursework. Approximately, 100 students per year will have the opportunity to learn state-of-the-art NDT and instrumentation techniques for concrete in a hands-on laboratory and field experience. UCF has a track record on research in NDT, and the proposed improvements will allow the transfer of knowledge to undergraduate students. UCF is committed to provide: (1) 100% matching funds for acquiring the equipment, (2) continued support for upgrading and mainta ining equipment on a regular basis, and (3) assigning specialized technician to take care of acquired equipment.
