Compressive strength - WikipediaCompressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength .Aggregate Crushing Value Test -Determine Aggregate .Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1.

To accomplish the entire work within the scope of time therefore necessary parameters were considered, the following activities were also performed according to the procedures discussed in the research work.8. STRENGTH OF SOILS AND ROCKSRock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2. The size dependancy is also found to exist for stiff fissured ...
