Widmans Laboratory Testing Engineer Lead Interview Questions and Answers

Non Destructive Testing (NDT) methods for concrete members include ultrasonic testing, rebound hammer test, and ground penetrating radar.

• Ultrasonic testing is used to measure the thickness of concrete, detect voids, and assess the quality of concrete.

• Rebound hammer test is used to determine the compressive strength of concrete by measuring the rebound of a spring-loaded hammer.

• Ground penetrating radar (GPR) is used to ...read more

Destructive testing of concrete specimens involves various types of tests to assess the strength and durability of the concrete.

• Compression test: Measures the maximum load a concrete specimen can bear before failure.

• Splitting tensile test: Evaluates the tensile strength of concrete by applying a diametrical load.

• Flexural test: Determines the flexural strength of concrete by subjecting a beam specimen to bending.

• Abrasio...read more
