As we know higher dimension of aggregate like 20mm and 40mm have lower density due to higher presence of air voids than 10 mm aggregates. 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 …

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, the 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]

In the majority of concrete works, aggregate sizes of 20 mm or smaller are used. To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix 20 mm and 10 mm coarse aggregates in the ratio of 70:30 or 60:40. It is recommended to stack different aggregate sizes to use them efficiently.

AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 µm (No. 200) sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).

Step 7 -Estimation of coarse aggregate content • The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given in Table. • The value from the table multiplied by oven dried weight of coarse aggregate required per cubic foot of concrete. • Volume of coarse aggregate = 0.63 x 27 (ft3/yd 3) = 17.01 (ft3/yd 3)

The ratio of fine to coarse aggregate is chosen as usual as 1:2. From the above table we know we need 250kg of total dry aggregate for our concrete. The general ratio of fine aggregate to coarse aggregate is 1:2, but it can be adjusted between 1:1.5 to 1:2.5 based on the grading of fine aggregate and size of coarse aggregate. Sand = 1 Part

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 …

· Calculation for Volume of Coarse Aggregate in 1cum of Concrete (M20):- Density of aggregate may go higher if void spaces decreases. As size of 5 mm aggregate has more density when compared with 20mm aggregate.

The Nature of the work decides which size of coarse aggregate should be used. The maximum size maybe 20 cm for mass concrete, such as in dams etc. and 63 mm for plain cement concrete work. For reinforced cement concrete work usually, 20 mm size aggregate is preferred. For structural concrete …
