    Effect of Continuous (Well-Graded) Combined Aggregate Grading on Concrete Performance Phase A: Aggregate Voids Content 2 Introduction It has been generally accepted that if the aggregate volumes are so chosen that the packing density of the combined aggregates is maximum then the amount of cementitious paste volume required for a

  • Combined Gradation Example - Montana Department of ...

    For this example, two coarse aggregates and one fine aggregate will be combined into the final product. These aggregates meet the requirements of Section 701.01 AGGREGATE FOR CONCRETE of the Standard Specification with the exception of Coarse Aggregate #2. Coarse Aggregate #2 doesn’t meet the gradation requirement of Section 701.01.
