New upgrade technology--The G5th air leak test detector

Application After the building construction or bridges are finished, the testing unit will test the structure every year to check whether it has some defect inside and whether some potential influence by the concrete. So the testing units will do some general testing work and record it for future comparation, such as concrete coating thickness testing, rebar location and distribution testing, rebar corrosion testing, concrete crack width and depth testing, concrete resistivity testing, concrete strength testing, and so on. Standard CECS 21:2000 Technical specification for inspection of concrete defects by ultrasonic method JGJ/T 152-2008 Technical specification for test of reinforcing steel bar in concrete GB 50204-2015 Code for quality acceptance of concrete structure construction
