Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the size of that material, or structural element, when applied. A force is applied to the top and bottom of a test sample, until the sample fractures or is deformed.. Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases

Testing the compressive strength of the aggregate particles is not normally carried out to determine its strength or suitability. This property is normally determined by a simpler method such as the Aggregate Crushing Value (ACV) or the Los Angeles Abrasion test which also gives a measure of the abrasion resistance and "toughness" of the aggregate.

At 28 days of curing, the compressive strength increases from 3.89 MPa for untreated soil, to 5.95 MPa for soil treated with 6% of lime content, that is, an increase of about 53%. From 6% to 9% of lime content, the compressive strength decreases from 5.95 MPa to 4.58 MPa, and thus it remains higher than that of the untreated soil.
