Depending on the mix design, either can be used to make essentially any range of concrete strengths. When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate.
A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150 mm. Most natural mineral aggregates, such as sand and gravel, have a bulk density of 1520 to 1680 kg/cum and produce normal-weight concrete with approximately 2400 ...

This standard is issued under the fixed designation C 127; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of
Normally sized as coarse aggregate or fine aggregate. Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate. Concrete Aggregates are produced to Australian Standards (AS 2758 ...
Density of 20mm and 40mm aggregate ranging between 1450 kg/m3 to 1550 kg/m3, consider density of 20mm aggregate is equal to 1550 kg/m3, it means weight of 1 cubic metre of 20 mm size aggregate is equal to 1550 kg.

fillers < No.100 (0.149 mm) < fine aggregates < No.4 (4.75 mm) < coarse aggregate < 4 inch (100mm) Aggregates consisting of both coarse and fine particles are called combined or mixed aggregates. Natural mixed aggregates taken from the deposits and used as they occur are called all-in aggregates or pit-run aggregates.
The surface area of coarse aggregate is less than fine aggregates. 6: Function in Concrete: The voids between the coarse aggregate are filled up by fine aggregate. Coarse aggregate acts as inert filler material for concrete. 7: Uses: Fine aggregates are used in mortar, plaster, concrete, filling of road pavement layers, etc.
Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.
Jul 01, 2020 · In Ref., the volume fractions of coarse granite aggregates mixed into concrete specimens were about 45%. The maximum aggregate size was 20 mm for concrete mixtures NC40 and NC60 and 10 mm for concrete mixture N90.
