内容記述 | Effects of minor components (ice, serpentine and glass) on the strength of consolidated aggregates (peridotite powder, <500 microns) are investigated by low-velocity impact experiments. The strength is represented by the critical impact velocity at which the largest fragment becomes a half of the original mass. Aggregates without minor components have the critical impact velocity of about 2m/s. Addition of less than a few weight percent of minor components is insignificant. When aggregates are added with more than 5 wt% ice (at -22℃), or with more than about 10wt% soda glass powder (≤74 microns) and heated at 700℃ for 15 hours, the critical impact velocity increases to about 9m/s, which is similar to that of pure ice. Addition of several weight percents of minor components significantly enhances consolidation, when mixtures are heated up to the glass transition temperature of amorphous minor components or the melting temperature of crystalline ones. Dehydration of hydrous minerals is not effective. | |||||
