CONCRETE STRENGTH IN FINISHED STRUCTURE. PART 3. NON-DESTRUCTIVE TESTING METHODS. INVESTIGATIONS IN LABORATORY AND IN SITU

HAALFASTHET I FAERDIG KONSTRUKTION. DEL 3. OFOERSTOERANDE METODER. LABORATORIE- OCH FAELTFOERSOEK

The methods considered are: the completely non destructive testing (ndt) methods; testing of ultrasonic pulse velocity, testing with Schmidt rebound hammer type n, combined testing using both these methods and the limited destructive (ldt) method: pull out testing. The values measured have been related to and compared with the compressive strength of specimens from drilled-out cores from structures. The report also sets out a methodology for the estimation of the compressive strength in a finished structure and the way in which the control of the finished structure could be valued regarding the accuracy of the method. The influence of the following properties on the test results is also considered: concrete mix composition and materials, treatment, moisture, age, temperature and test methods. The report includes an English summary of 8 pages. /TRRL/
