4 20 Mm Aggregate Grading

What is Grading of Aggregates? and Its limits [Civil Planets]

Significance of Grading 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.

Grading of Aggregate and Fineness Modulus of grading of

When The aggregate fraction above 4.75 mm to 80 mm is termed as coarse aggregates and from 4.75 mm be to 150 microns as fine aggregate. All in aggregate comprises both fine and coarse aggregate. More about sieve analysis grading of aggregate

To complicate matters more, for fine and all-in aggregate, where D <= 8mm, the standard requires producers to declare a "typical grading", which, where required, must be within a given Tolerance Category designated according to a set ± value on the D/2 sieve, i.e., G TC 10, G TC 20 or G TC NR (no requirement). A typical quarry dust could be designated 0/4 G A 85 G TC 20.

HOW TO CLASSIFY AGGREGATES ACCORDING TO SIZE?

07-07-2014· IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4. The four grading zones become progressively finer from grading Zone-1 to grading Zone-4. 90% to 100% of the fine aggregate passes 4.75 mm IS sieve and 0 to 15% passes 150 micron IS sieve depending upon its grading zone.

Aggregate Effects On Properties Of Concrete » CivilScoop

Flaky aggregate are the aggregates whose least dimension is less than 3/5th of its mean dimension i.e. the mean dimension of an aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. Now, if the least dimension is less than 18 mm (3/5 x 30 = 18 mm) then the aggregate is flaky. Elongated:
