DIAGNOSTICS - COMPARATIVE TESTS ON FERROCONCRETE

AREA - FERROCONCRETE STRUCTURAL ELEMENTS

APPLICATION TECHNIQUE

Serie of non destructive and partially destructive , tests and checks on a limited ferroconcrete area to obtain a check up of both iron frame and concrete.
The sequence consists in a visual critic survey, a Magnetometric survey on iron frame, an oxidation potential Measure, an ultrasonic analysis, an extractive "pull out" test and a carbonation depth millimetric measure.

RELATED DIAGNOSTICS
- Squashing test (on logged sample)
- Concrete chemical analysis
- Corrosion potential measure
- Iron sample traction test
- Gammagraphy

OBTAINABLE RESULTS
-	Examined zones referring diagnostics form showing each test and process result.
DETECTABLE DATA
-	Structure charachterization depending on concrete omogeneity and resistance and on frame presence and geometry.
-	US speed and sclerometric index comparation makes it possible to collect Rck values using the higly reliable SONREB method. These values are then corrected using extractive "pull out" test data.

Non destructive ferroconcrete tests with sampling on 1mq structure surfaces, including the following analysis and tests:
- preliminary geometric analysis;
- magnetometric check of the frame and iron cover thickness (following UNI7062 rule standards);
- extractive "pull out" tests (following UNI7997 and ASTM c900 rules standards);
