Penetrometer
- Type A, B, and C soils - [3]. Penetrometer reading of Type A - cohesive clay - is 1.5 tons per square foot, or 23 psi. Note that this is 100x less than psi of concrete.
- 'Compressive strength of unconfined sample' is the uniaxial load, unconfined, in psi. This is not the same as load bearing capacity of soil, measured in psf. Clay is 1500 psf.
