Detecting cracks due to steel corrosion in reinforced cement mortar using intermodulation generation of ultrasonic waves
نویسندگان
چکیده
It has been studied the sensitivity of technique intermodulation ultrasonic waves to detect different damage states concrete due embedded steel corrosion. Accelerated corrosion tests have conducted on reinforced cement mortar specimens, while monitoring appearance and width evolution visible surface cracks performing measurements. established a statistically acceptable “upper control limit” for initial (undamaged) Intensity Modulation Ratio (R) values. After subjecting samples tests, it was observed that greater degree damage, higher value ranges variability R.

Experimental Study of Cement Mortar-Steel Fiber Reinforced Rammed Earth Wall
Rammed earth construction is an ancient technique which has recently attracted renewed interest throughout the world. Although rammed earth is currently regarded as a promising material in the construction industry in the context of sustainable development, it is difficult to quantify its bearing capacity, mechanical performance, as well as retrofitting approach, which discourages people from l...
متن کاملNumerical Simulation of Monitoring Corrosion in Reinforced Concrete Based on Ultrasonic Guided Waves
Numerical simulation based on finite element method is conducted to predict the location of pitting corrosion in reinforced concrete. Simulation results show that it is feasible to predict corrosion monitoring based on ultrasonic guided wave in reinforced concrete, and wavelet analysis can be used for the extremely weak signal of guided waves due to energy leaking into concrete. The characteris...
متن کاملMonitoring of corrosion damage using high-frequency guided ultrasonic waves
Due to adverse environmental conditions corrosion can develop during the life cycle of industrial structures, e.g., offshore oil platforms, ships, and desalination plants. Both pitting corrosion and generalized corrosion leading to wall thickness loss can cause the degradation of the integrity and load bearing capacity of the structure. Structural health monitoring of corrosion damage in diffic...
متن کاملPossibility of Determining Steel Grain Size Using Ultrasonic Waves
The microstructure of steel is decisive for its chemical, physical and mechanical properties. Depending on the parameters characterising liquid metal as well as the parameters of the steel casting influencing the crystallisation process, the macrostructure of casts and ingots consist of three, two or only one crystallisation zone. In steel ingots, its most frequent by consist of three zones: ch...
متن کاملMonitoring Corrosion of Steel Bars in Reinforced Concrete Structures
Corrosion of steel bars embedded in reinforced concrete (RC) structures reduces the service life and durability of structures causing early failure of structure, which costs significantly for inspection and maintenance of deteriorating structures. Hence, monitoring of reinforcement corrosion is of significant importance for preventing premature failure of structures. This paper attempts to pres...
