Metrics and Sieve Sizes Concrete Construction Magazine

The larger the number the smaller the size of the stone Stone number is defined by the amount of an aggregate that will pass through specific sieves by mass percent The numbered sieves refer to the number of square openings per inch 25 4 mm so a #4 sieve has 1/4 inch 4 75 mm square openings; a #16 has 1/16 inch 1 18 mm square openings

Practical Grading of Aggregates Concrete Technology

In particular an excess of material between 1 20 and 4 75 mm test sieves will produce a harsh concrete which may be compacted by vibration but difficult to place by hand If the same workability is to be obtained using aggregates with grading curve No 4 and 1 the latter would require considerably higher water content

What Is the Grading Limits for Coarse Aggregates

The grading of coarse aggregate may be varied through wider limits than that of fine aggregates since it does not affect the workability uniformity and finishing qualities of concrete mix As per IS 383 the grading limit of coarse aggregate both for single size as well as graded should be as per the table given below

Refers to a gradation that contains only a small percentage of aggregate particles in the mid size range The curve is flat in the mid size range Some PCC mix designs use gap graded aggregate to provide a more economical mix since less sand can be used for a given workability HMA gap graded mixes can be prone to segregation during placement
