Aggregate size| Concrete Construction Magazine | Concrete ...

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. A realistic appraisal of the recent data for several different aggregates must lead to the conclusion that size of aggregate, within a reasonable range, is of less importance to concrete strength than other ...

Classification of Aggregates Based on Size

The most common size of aggregate used in the concrete mix is 20 mm for coarse aggregate and particle size less than mm for fine aggregate. Courtesy Flickr According to nature of the formation of aggregates, they are classified as:

Aggregates for Concrete GreenSpec

• Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. A larger size, 40mm, is more common in mass concrete. • Larger aggregate diameters reduce the quantity of cement and water needed.


A coarse aggregate which has the sizes of particles mainly belonging to a single sieve size is known as single size aggregate. For example 20 mm single size aggregate mean an aggregate most of which passes 20 mm IS sieve and its major portion is retained on 10 mm IS sieve.
