To establish suitability for use in Agency concrete, MnDOT performs testing to determine various aggregate properties on concrete aggregate sources in accordance with MnDOT Specifications 3126, 3131, and 3137.
Concrete Aggregate Properties Include:
OD SPG - Oven Dry Specific Gravity
SSD SPG - Saturated Surface Dry Specific Gravity
ABS - Absorption
FM - Sand Fineness Modulus
ASR - Alkali Silica Reactivity: 14-Day Unmitigated Results
