Samples were tested using a cylinder, tamping rod, and compression machine. The crushing value obtained was 20.1%, which is below the 35% standard, indicating the aggregates can …
When "uncrushing" the solution (i.e., mapping it from the presolved model back to the original model), a more accurate solution is found that is taken instead. This can imply a change in the objective value. The warning tells if the objective value is degraded or improved in this step. Constraints that can cause this behavior are big-M constraints.
1. objective. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. 2. apparatus required
