| 摘要： | The goals of this study were to: Characterize Minnesota’s aggregates with a range of carbonate content using a simple, rapid test, such as the Iowa pore index test; Relate to Iowa pore index values and other aggregate properties (such as pore structure and absorption) that are known to affect freeze-thaw durability; and Re-evaluate the current MnDOT specification limits on Class B and Class C aggregates to allow more sources of aggregate to be used in concrete construction. |
