Measurement of Air Content in Concrete

320
Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
The pressure method,...

Area of Science:

  • Environmental Science
  • Occupational Health
  • Engineering

Background:

  • Construction sites generate particulate matter (PM), posing significant health risks to workers and nearby residents.
  • Effective real-time management of PMs across diverse site locations is crucial but currently lacking.
  • Existing monitoring systems do not adequately address the dynamic and widespread nature of PM generation on construction sites.

Purpose of the Study:

  • To develop an innovative Internet of Things (IoT)-based system for real-time, multi-location particulate matter monitoring and management on construction sites.
  • To create a practical solution addressing the limitations of current PM management strategies in dynamic construction environments.
  • To enhance occupational safety and public health by enabling proactive control of airborne pollutants.

Main Methods:

  • Development of integrated system components: specialized measuring instruments, a robust network infrastructure, and user-friendly program services tailored for construction environments.
  • Leveraging Internet of Things (IoT) technology for seamless data transmission and real-time analysis from multiple monitoring points.
  • Rigorous performance certification and field application testing to validate system efficacy and reliability.

Main Results:

  • The developed Construction Site PM Monitoring System (CPMS) achieved Grade 1 for reproducibility, relative precision, and data acquisition rate.
  • The system attained Grade 2 for accuracy and coefficient of determination, receiving an overall performance certification of Grade 2.
  • CPMS demonstrated 74.2% accuracy, addressing a key limitation of traditional light-scattering PM measurement methods.

Conclusions:

  • The developed IoT-based CPMS provides a viable and effective solution for real-time, multi-location particulate matter monitoring in construction settings.
  • The system's performance metrics indicate its reliability and potential to significantly improve air quality management and health protection on construction sites.
  • The CPMS represents a significant advancement in addressing the challenges of particulate matter control in dynamic construction environments.
