Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.
The volume of this is dependent on the fineness modulus of fine aggregates and the maximum size of coarse aggregates. Use the bulk volume, bulk density, the relative density, and water to determine the absolute volume. This gives a percentage of this that is in the absolute volume of the concrete.
Bulk Density . These materials have a bulk density of 600–700 kg m −3, which can be compared to a typical bulk density of hard coals in the region of 1000 kg m −3. Fluffy and dry materials like dry sawdust, straw, grass, and shredded paper will often be lighter than 200 kg m −3 .
Jul 30, 2012· If a statement is like: A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. For testing, British Standard (BS 812) has specified the degree of compaction. These are; Loose ( Un-compacted) Compacted; The test will be carried out by using metal cylinder having prescribed depth and diameter and the bulk density is to …

If the particles are of the same size, then it can be packed to a limited extent but when the smaller particles are added, the voids get filled with them and thus the bulk density increases. For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement.
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.
The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). [2] Relative Density of Aggregate [1]
Physical Properties of Aggregate: Bulk Density The cylindrical measure is filled about 1/3 each time with thoroughly mixed aggregate and tamped with 25 strokes by a bullet ended tamping rod, 16 mm diameter and 60 cm long. The net weight of the aggregate in the measure is determined and the bulk density is calculated in kg/litre.
,fine aggregate, coarse aggregate aswell hematite aggregate of size 20mm and 10mm are tested before use in trial mix of concrete. The relevant tests for material concern as per IS 456: 2000 i.e. Indian standard plain and reinforced concrete code of practice.
COARSE AGGREGATES Section 904.03 defines the acceptable limits for all uses of coarse aggregates. Coarse aggregates are divided into classes based on quality requirements as noted in the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which m eet the requirements for all INDOT uses.
DETERMINATION OF BULK DENSITY AND VOIDS 3.1 Object - This method of test covers the procedure for determining unit weight or bulk density and void of aggregates. NOTE 1 - The bulk density is the weight of material in a given volume, and for the purpose of this standard it is measured in kilograms per litre.
