If talking in general terms it's about 1500–1750kg per cum. For accurate calculation, we will be needing Bulk density of Agg and Vol of air and specific gravity of Aggregate first.

Consequently, the cement content must also be increased to maintain the water-cement ratio. Generally, flat and elongated particles are avoided or are limited to about 15 percent by weight of the total aggregate. Unit-weight measures the volume that graded aggregate and the voids between them will occupy in concrete.

1. Scope. 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.

For reinforced cement concrete work usually, 20 mm size aggregate is preferred. For structural concrete common materials like gravel and crushed stone are used. Also, Read – What is M Sand? Properties, advantages, Disadvantages. Bulk density of Aggregate. It is the weight of aggregate needed to fill a unit volume of the container.

40 mm size aggregate wieght per cum depends upon the type of rock of which the aggregate is made of. But in general, the 40 mm size aggregate may have 1.6 MT to 1.8 MT of wieght in 1 CUM volume. 1.8 is for the high density rocks such as granite etc. Sand stone aggregate found in central India, say in Rajasthan, MP is 1.6 MT per 1 CUM

Where Gs is specific gravity and γ is bulk density. 1.2 Objective The objective of the test is: To determine the unit weight (Bulk Density) and voids of aggregates. 1.4 Theoretical Background The bulk density of an aggregate can be used for judging in the quantity by comparing with normal density for that type of aggregates.

Jul 16, 2017· The rodded unit weight is computed in kg/m 3 from the net weight of the rodded aggregates in the bucket divided by its volume. EXPLANATION OF COMPUTATIONS AND DATA SHEET – Computations: Calculate the rodded unit weight as follows: Calculate the rodded unit weight to the nearest 10 kg/m 3. – Data sheet: There are no special data sheets for ...

What is the weight of 10mm,20mm,40mm aggregate per cubic ft in kg?.. Answer / prakash. considering density of aggregate 1600kg/ cum. 1 cft aggregate will weight= 1600/35.32= 45.30kg. 10mm aggregate will have higher density than 20mm & 40mm. due to less voids. Similarly 20mm will have higher density.

The unit weight of coarse aggregate depends on the size, gradation of aggregates from 20 mm to 6 mm, density of the rock from where the aggregates are produced. Generally very hard rocks like granite, gneiss, derived from igneous rocks are pounded...

Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3) .

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft

normal weight aggregates and are known as normal weight units.
