Bond Work Index - an overview | ScienceDirect Topics

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Improving durability of heat-cured high volume fly ash ...

One can note that the autogenous shrinkage increased with the reduced particle size of fly ash. The heat-cured mortar with ultrafine fly ash with D 50 of 2.51 μm presented the highest autogenous shrinkage. Under the same content (50 wt%), the autogenous shrinkage of F3-50 was increased by 30.8% and 27.1%, compared to F1-50 and F2-50, respectively.
