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.

[PDF]Box Compression Test Strength (BCT) Calculator Estimates the BCT of a regular slotted container (RSC) for a moment with flutes positioned vertically. (Note that BCT is not stacking strength, which is the maximum load a box can handle throughout the distribution cycle.)

Feb 02, 2013 · The Effect of Magnesium Stearate on Crushing Strength of Tablets. The crushing strength of tablets was generally found to decrease with the increase of blending time (Fig. 2). The Y-axis in Fig. 2 is presented as the crushing strength of tablets divided by their individual weight . This operation made the values better comparable.
