Each of the mentioned morphological indices is just calculated for one aggregate. In this study, 200 particles were randomly selected from each size fraction out of four size groups for one aggregate sample. Therefore, the average value of each index has to be calculated for a total of 200 aggregates of each size group.

22-7-2016 · Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 % of

### Effect of maximum coarse aggregate size on …

The test results indicated that the larger maximum coarse aggregate sizes induce larger heterogeneity of specimens. On the other hand, the pure rate DIFs did not exhibit a dependency on the maximum coarse aggregate size. Based on these results, guidance as to the maximum coarse aggregate size of concrete specimens for SHPB tests is provided.
