Specimen Type for Concrete Strength Test
Easyconcretecompressive strength
In common U.S. practice, concrete compressive strength is measured by loading which type of specimen?
- ASieve
- BCylinder
- CPycnometer
- DProctor mold
Show solutionHide solution
Answer: B. Cylinder
A concrete cylinder is loaded in compression to failure, and compressive strength is calculated as failure load divided by cross-sectional area. A sieve measures gradation, a pycnometer measures density or specific gravity, and a Proctor mold is used in soil compaction testing.
