Effect of coarse aggregate type on chloride ion …

Each coarse aggregate type was subjected to sieve analysis to separate the different aggregate fractions for subsequent remixing. Quantities of the different ingredients needed to prepare a concrete mix following the MnDOT specifications were calculated. Fig. 2 shows the particle size distribution of coarse and fine aggregates used in the concrete mix design.

Fine Aggregate The other type of aggregates are those particles passing the 9.5 mm (3/8 in.) sieve, almost entirely passing the 4.75 mm (No. 4) sieve, and predominantly retained on the 75 µm (No. 200) sieve are called fine aggregate. For increased workability and for economy as reflected by use of less cement, the fine aggregate should have a rounded shape.

Shape, Size - Coarse Aggregates

Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.
