3. The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand. It appears that optimum maximum size, so far as strength is concerned, will vary for different aggregates, different cement factors, different test ages and probably other conditions. 4. Aggregates - Portland Cement AssociationCoarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder.

Flaky aggregates. Elongated aggregates. Flaky and elongated aggregates.

Classification of Aggregates Based on Size

In nature, aggregates are available in different sizes. The size of aggregate used may be related to the concrete mix proportions, type of the work etc. The size of aggregate is mainly divided into two categories:01. Fine Aggregate. 02. Coarse Aggregate Classification of Aggregates Based on SizeThese materials include gravel, sand, or crushed stone mixed with water which is all added to the cement mixture to create concrete. The most common size of aggregate used in the concrete mix is 20 mm for coarse aggregate and particle size less than 4.75 mm for fine aggregate.
