Abstract

Concrete failure will lead to serious safety precautions in wall performance of a building structure. It is one of the biggest challenges for engineers to inspect and maintain the quality of concrete throughout the service years in order to prevent structural deterioration. Up to date, a lot of research is ongoing to develop different instruments to inspect concrete quality. Detection of moisture ingress is important in structural monitoring of concrete. This paper presents a novel sensing technique using smart antenna for nondestructive evaluation of moisture content and deterioration inspection in concrete blocks. Two different standard concrete samples (United Kingdom and Malaysia) were investigated in this research. Electromagnetic (EM) sensor was designed and embedded inside the concrete to detect the moisture content in structures. In addition, Computer Simulation Technology (CST) software was used to validate the theoretical model of EM sensor against the test data. The results demonstrated that EM sensor at 2.45 GHz frequency is capable to detect the moisture content in concrete with linear regression of R2=0.9752. Furthermore, identification of different mix ratio of concrete were successfully demonstrated in this paper. In conclusion, EM sensor is capable of detecting moisture content in non-destructive manner and could be a potential technique for maintenance and quality control of the building performance.
