18-03-2021 The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520- 1680 kg/m3 (95-105 lb/ft 3)

The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m3 or 75 to 110 lb/ft3. Relative Density or

16-08-2020 Density of cement is 1440kg/m3 or it is measured in other unit- their density is 1.440 in g/cm3, 90 in lb/ft3 and 14.40 in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3

10-04-2020 And percentage of voids present in coarse aggregate is calculated with the help of specific gravity of coarse aggregate and their Loose bulk density by the following formula % of voids = {(Gs _R)/Gs}×100. Where Gs = specific gravity of coarse aggregate and their value is 2.65. R = loose bulk density of coarse aggregate = 1.337 kg/L

Bulk Density = Mass / volume. 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/m ...

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.

As can be observed from the above figure, the maximum bulk density of a mixture of fine and coarse aggregates is achieved when the mass of the fine aggregate is around 35 to 40% of the total mass of the mixture; Corresponding to the maximum bulk density of a mixture of fine and coarse aggregates, there is minimum cement

The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a). The bulk density

Note - The higher the bulk density, the lower is the void content to be filled by sand and cement. Factors affecting bulk density - The value of bulk density is governed by factors discussed below. Grading of aggregates - Well graded aggregates result in the least voids and hence more is the bulk density.

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
