Corrosion Detection of Reinforcement of Building Materials with Piezoelectric Sensors

Abstract

The extensive use of reinforced materials in the construction industry has raised increased concerns about their safety and durability, while corrosion detection of steel materials is becoming increasingly important. For the scientific management, timely repair and health monitoring of construction materials, as well as to ensure construction safety and prevent accidents, this paper investigates corrosion detection on construction materials based on piezoelectric sensors. At present, the commonly used corrosion detection methods include physical and electrochemical methods, but there are shortcomings such as large equipment area, low detection frequency, and complex operation. In this study an improved piezoelectric ultrasonic sensor was designed, which could not only detect the internal defects of buildings while not causing structural damage, but also realize continuous detection and enable qualitative and quantitative assessment. Corrosion detection of reinforced building materials with piezoelectric sensors is quick and accurate, which can find hidden dangers and provide a reliable basis for the safety of the buildings.

Progress in Sensors for Monitoring Reinforcement Corrosion in Reinforced Concrete Structures—A Review

“…Peng et al [143,144] also analysed sensors based on lead zirconate titanate and modified Fe, Mn, Ca (PZT-4-type), and La, Nb (PZT-5-type). On the whole, their results are close to those obtained in [142].…”

“…Peng et al [142] suggested a piezoelectric sensor based on ceramics (lead zirconate titanate) and composite materials used to isolate the sensor, screen noise, and enhance the sensor's signal. The authors assessed the corrosion condition and the degree of damage to steel reinforcement based on the signal's amplitude.…”

A systematic review of construction workers’ health and safety research in India

“…It should be noticed that articles from other countries that focus on safety issues in the Indian construction industry were also considered in this study. The scope of this review-based study focused only on human-centered safety management and excluded other safety issues such as material or structural safety of buildings (Peng, 2017) that do not directly focus on construction employees' health and safety. Finally, a total of 64 journal documents were extracted after careful refining.…”

A science mapping approach based review of construction safety research

“…were also excluded. Further, it should be noticed that the the scope of this review-based study is human-centered safety management, it covered the safety planning and site management, but excluded other safety issues that do not direct focus on construction employees' safety, for example, structural or material safety for buildings (Peng, 2017). After the final round of screening, ultimately a total of 513 journal articles were selected as the literature sample for the follow-up scientometric analysis.…”
