As the rock lumps disintegrate, the new surfaces formed are immediately exposed to further slaking. Additionally, a very small cycle size might require a very lengthy test in order to replicate equivalent fatigue damage. The individual Document downloaded The cycle size should not be larger than the largest cycle observed in the measured loading or else the failure mode may be changed. of this Agreement. 937 Commercial Street The purpose of this lab is to access the resistance offered by a rock sample towards weakness and disintegration when subjected to standard cycles of drying and wetting. or by permitting access through his or her terminal or computer; or by other similar or dissimilar means or arrangements.
