Which test is commonly used to determine rock strength for construction suitability?
A. Permeability test
B. Schmidt hammer test
C. Sieve analysis
D. Vane shear test
Answer: Option B
Solution (By Examveda Team)
The Schmidt hammer test provides an estimate of rock surface hardness and correlates it to unconfined compressive strength.It is fast and non-destructive.This Question Belongs to Geological Engineering >> Engineering Geology For Construction
Uniaxial Compressive Strength (UCS) test, Brazilian Tensile Strength test, Triaxial Compression test and Point Load Strength Index test are commonly used to determine rock strength. Schmidt hammer test is a non destructive testing procedure to determmine the strength of hardened concrete. So, i dont think any of the given option is the right answer!
