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.

The compressive strength and crushing time follow an increasing trend and implies that the crush- ing time is directly proportional to the compressive strength of the rocks, that is, the harder the rock, the more the crushing time under the impact of the jaw crusher. The general size distribution plot in Fig. 2 is the upward trend of each plot

Similarly, the dynamic compressive strength, strain rate, and pressure data of the SHPB compression test of limestone samples are all listed; the fitting curves are shown in Figures 11 and 12. Figure 11 shows that the dynamic compressive strength has a linear relationship with the impact pressure, and the correlation is significant.

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.

For this purpose, the mineralogical, physical, and mechanical properties of various hard rocks were determined. A new compressive crushing value (CCV) testing methodology was proposed. The results obtained from CCV tests were compared with those from mineralogical inspections, rock strength as well as mechanical aggregate tests.

Crushing Strength. Sometimes known as compression strength parallel to the grain, this is a measurement of the wood’s maximum crushing strength when weight is applied to the ends of the wood (compression is parallel to the grain).
