Diagnosis and repair techniques of deteriorated reinforced concrete structures
A few words about the author ...
On this website I describe the concrete test methods and repair techniques I have been using in my civil engineering practice for many years:
Concrete Quality & Strength
- Cut out concrete cores for laboratory tests
- Rebound hammer (Schmidt hammer) - concrete surface uniformity & strength by rebound
- Pull-out test – in-place concrete compressive strength
- Ultrasonic pulse velocity by through transmission – concrete compressive strength & inner defects recognition
- Pull-off test – bond strength of overlay or tensile strength of substrate
- GWT in-place test - resistance to water penetration
- Width of cracks measurement and monitoring
Concrete Geometry
- Cover meter – pulse induction method to give cover and bar size of reinforcement
- Impact Echo method - to give element thickness or inner defects location
- Ground Penetrating Radar - GPRs system for imaging of rebars, post-tensioning, services, inner defects and moisture in concrete
Defects detection in concrete
- Ultrasonic pulse velocity by through transmission
- Impact Echo method – to locate defects in concrete due to structural damage or poor concrete placement
- Slab Impulse Response method - rapid testing for poor concrete placement and voids beneath slab pavements or foundations
- Ground Penetrating Radar - GPRs system - detecting internal voids, locating rebars, tendons, pipes
- Ultrasonic pulse-echo method (MIRA) - 3D concrete imaging system for flaws and thickness measurement – introduction to the method
- Infrared Thermography - locating leakages, damp areas, delamination – introduction to the method
Corrosion of steel and concrete
- RCT - rapid chloride penetration test
- Rainbow Indicator – carbonation depth and profile
- Cover meter – pulse induction method to give cover and bar size of reinforcement
- Half-cell potential method
- Concrete resistance
- Galvanic pulse method
