· Effects of lime and pulverization quality on unconfined compression strength and failure strain values. Unconfined compression strength (q u) for specimens prepared with natural soil ranged between 307 and 432 kN/m 2. Pulverization quality did not have a definite effect on unconfined compression strength values for natural samples.
