CLASSIFICATION OF AGGREGATE:a)CLASSIFICATION BASED ON SIZE: >Coarse aggregate: Aggregate which retained on the No.4 (4.75mm) sieve. The function of the coarse aggregate is to act as the main loadbearing component of the concrete. >Fine aggregate: Aggregate passing No.4(4.75mm) sieve and predominately retained on the No.200 (75µ) sieve.

What Is Coarse Aggregate Requirements of

05.01.2021  #2 Coarse Aggregates- The Aggregates which has a size of more than 4.75 mm is known as Coarse aggregate. The Aggregate sizes which range from 4.75 mm to 80 mm are the coarse Aggregates and the 150 microns to 4.75 mm aggregates are known as Fine Aggregates. The size 4.75 mm is common for both fine Aggregates as well as coarse Aggregates.

What Is Grading Of Aggregates? And Its Limits

The aggregates are graded as per IS code 383, when the aggregate size is less than 4.75mm is called fine aggregate more than 4.75mm is called coarse aggregate. The aggregate gradation is determined by the fineness modulus method where aggregates are passing through the sieve as per IS standard to classify its size.

How Coarse Aggregate Affects Mix Design of

Smaller maximum size of coarse aggregate would require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix. So, for the same workability, 40mm down aggregate would have lower water/cement ratio, thus higher strength when compared to 20mm down aggregate. Because of its lower water demand, advantage of higher maximum size of coarse aggregate

Classification of Aggregates as per Size and

Coarse Aggregate. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. the size range of various coarse aggregates

Gradation, or particle size distribution, is the dispersal of individual particle sizes across the entire sample. Aggregate gradation is typically reported in graphical form by plotting each of the particle sizes on a semi-logarithmic chart and drawing a best-fit curve between the points. The full procedure is outlined in ASTM C136 (AASHTO T-27).
