Concrete Assessment, Pathology, and Monitoring
Concrete assessment, pathology, and monitoring are essential technical processes aimed at ensuring the durability, safety, and serviceability of concrete structures throughout their lifespan.
Concrete Assessment
This involves evaluating the current condition and performance of concrete structures using various inspection and testing techniques.
Main methods and stages:
Visual inspection (EN 1504-9)
Non-destructive testing (NDT) such as Schmidt hammer (ASTM C805), ultrasonic pulse velocity (ASTM C597), and rebar detection
Core sampling and laboratory analysis (ASTM C42)
Chemical and petrographic analysis
Purpose: To detect deterioration, defects, and the root causes of damage and distress.
Concrete Pathology
This refers to the diagnosis and analysis of defects or failures in concrete, identifying causes such as corrosion, alkali-silica reaction, sulfate attack, freeze-thaw cycles, and poor workmanship.
Main approaches:
Crack mapping and monitoring
Chloride and carbonation depth testing (ASTM C1152, EN 14630)
Microscopic examination
Chemical analysis for aggressive ions
Advantages: Enables data-driven maintenance, repair, and rehabilitation strategies, preventing costly failures.
Concrete Monitoring
Monitoring involves establishing long-term tracking systems to observe the structure’s behavior and durability under service loads and environmental exposure.
Techniques:
Installation of sensors (strain gauges, humidity, temperature, corrosion sensors)
Periodic on-site testing and data logging
Automated structural health monitoring (SHM) systems (ISO 16311, ACI 228.2R)
Key benefits: Early warning of deterioration, enhanced safety, proactive asset management.
Applications
Bridges, dams, tunnels
Industrial floors and structures
Nuclear, oil & gas, and infrastructure projects
Maintenance of critical facilities
