Nondestructive tests for determining compressive soil strength of cement stabilized soils

Nondestructive impact hammer tests were made on cement-stabilized noncohesive soils using a Clegg impact soil tester and a Proceq Type PT test hammer. Compressive strength of the stabilized soils varied from about 5 to 1,000 psi. Curves correlating impact hammer values with cement-stabilized soil compressive strength were developed for each of the test hammers. These curves can be used to correlate in situ nondestructive test values with the compressive strength of cement-stabilized soils.
