Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.

Jan 24, 2013 By the CT 382 definition, the maximum aggregate size is 34 and the nominal maximum aggregate size is 12. In the November 2011 version of CT 202, nominal maximum aggregate size is defined as one sieve size larger than the first size to retain more than 10. By this definition the nominal maximum aggregate size for the material example

because some lightweight aggregates have fines with higher bulk specific gravities than the coarse aggregate sizes. This is due to the difference in cellular structure of the fine and percentage of internal voids than the smaller sizes. In dealing with such materials a correction must be made in the limits if sieve analyses are run by weight.

0.45 Power Method Gradation Chart Typical Uses. The 0.45 Power Gradation Chart method is often used in gradings of aggregates for asphalt and for roller compacted concrete or hydraulically bound materials. In this method the aggregate gradings are plotted on a cumulative percent passing graph with the sieve sizes raised to the power of 0.45.

Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm No. 4 sieve in diameter to dense, sandsize grains passing a 4.75 mm No. 4 sieve. Grinding reduces the particle size to cement fineness

Aggregate Size Effects As the maximum size aggregate increases, the amount of paste needed for a given slump decreases. The maximum aggregate size used in a concrete mix is dictated by the size of the structural member and the spacing between reinforcing steel.

The size of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. basically, all other aggregates which are retained on 4.75mm IS sieve while sieve analysis is performed. According to sources of coarse aggregates, it can be further classified as a Uncrushed Gravel or Stone It results from natural disintegration of rock.
