In the same way 10 mm, 20 mm and 40 mm aggregates shall be combine in the ratio of 1:1.5:3 to get a graded coarse aggregate. Advertisements Fine aggregate of Zone II as per IS: 383-1970 is generally suitable for pumped concrete provided 15 to 30 percent sand should pass the 300 micron sieve and 5 to 10 percent should pass the 150 micron sieve.
Physical Prosperities of Aggregate : Grading Grading is the particle-size distribution of an aggregate as determined by a sieve analysis using wire mesh sieves with square openings. As per IS:2386(Part-1) Fine aggregate : 6 standard sieves with openings from 150 μm to 4.75 mm. (150 μm, 300 μm, 600 μm, 1.18mm, 2.36mm,
1.1 This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.
This results in vitrified (glassy) material with a sand- like appearance, with particles typically 1 mm to 5 mm size It is light weight aggregate, which needs further processing to improve the bulk density to more than 1.35 kg/I for its use as normal weight aggregate.

Weight of Coarse Aggregate. The normal weight of stone aggregate in loose state is= 1400 to 1600 kg per cum, but for illustration an average value 1500 kg per cum is considered. Grading of coarse aggregate. Proper graded material should be used for achieving good bond stress.
Concrete Mix Design. Introduction. The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
These variables determine strength, density, as well as chemical and thermal resistance of the finished product. Aggregate consists of large chunks of material in a concrete mix, generally a coarse gravel or crushed rocks such as limestone, or granite, along with finer materials such as sand.

For sand bulk density is 1450-1650 kg/m^3. and the bulk density of aggregate depends upon their packing, the particles shape and size, the grading and the moisture content.For coarse aggregate a higher bulk density is an indication of fewer voids to be filled by sand and cement.
