density lower than normal density aggregates (natural sand, gravel, and crushed stone), sometimes and is referred to as low density aggregate. Structural lightweight aggregate-Structural aggregate meeting the requirements of ASTM C 330 with bulk density less …
The bulk density of an aggregate sample is determined by filling a unit volume cylindrical container with aggregates at a specific degree of compaction. Thus it depends on the degree of compaction of aggregates during filling of the container and accordingly has been divided into categories of loose and compact bulk density.
performance record, the aggregates should be tested before they are used in concrete. The most commonly used aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale,
Density of coarse Aggregate. Following are the density of coarse aggregate. Broken stone ballast. Dry well shaken=1600—1870 kg/cum. Perfectly wet =1920—2240 kg/cum. Shingles 3-38mm=1460 kg/cum. Gravel. Loose = 1600 kg/ cum. Un disturbed =1920-2160 kg/cum.

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.
These values for density of some common building materials were collected from sites across the Internet and are generally in agreement with multiple sites. Most are from BOCA or ASAE tables. However, if you have values that you believe are more accurate, use them for your calculations, and please send me an e-mail to let me know what your ...
Gravel, Chippings and most Pebbles: Cobbles: Rubber Chippings: Useful Coverage recommended depth 50mm: Useful Coverage recommended depth 100mm: As rubber chippings have a different density than gravel, please use the following table to calculate quantities required: 1 bag = 0.25m 2 approx. 1 bag = 0.12m 2 approx. 4 bags = 1m 2 approx. 8 bags ...
A. High-density aggregates generally consist of high-density minerals or rocks, or they consist of man-made materials, such as steel or iron. High-density aggregates are used to produce concrete that has higher than normal density, usually for radiation shielding or an application where high-density concrete is needed for counter balancing ...
Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3). Here, for coarse aggregates, the standard test method has been explained in ASTM C 127(AASHTO) and for fine aggregates, the standard test method has been explained in ASTM C 128 (AASHTO).
fine aggregate specific gravity and absorption for mineral aggregates used in asphaltic concrete, other than asphaltic concrete friction course, shall be determined on pass No. 4 material. "Fine aggregate" as herein referenced will be either pass No. 4 or pass No. 8 material.
MATERIALS 208–2.1 AGGREGATE. Aggregates consist of both fine and coarse fragments of crushed stone, or crushed gravel mixed or blended with sand, screenings, or other similar approved materials. ... 208–3.6 ACCEPTANCE SAMPLING AND TESTING FOR DENSITY. Aggregate base course will be accepted for density on a lot basis.
Rounded Aggregate The rounded aggregates are completely shaped by attrition and available in the form of seashore gravel. Rounded aggregates result in the minimum percentage of voids (32 – 33%) hence gives more workability. They require a lesser amount of water-cement ratio. They are not considered for high-strength concrete because of poor ...
The density of 10mm aggregate is the weight of the aggregate per its volume. Formula. ρ = m / V. ρ: Density. m: mass. V: Volume. Density vs Specific Weight vs Specific Gravity. I would like to point out that there are conceptual differences between density, specific weight and specific gravity. Follow the link if you want to learn more about ...
The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).
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 …
To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. The volume formula for a rectangular (or square) box in cubic feet is height (ft) x width (ft) x length (ft), as seen in the figure below: For example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft ...
So density of aggregate is not fix but it ranging between 1420 kg/m3 to 1680 kg/m3. Weight of aggregate in kilogram depends on density of aggregate and size of aggregate. Lesser dimension of aggregate have high density due to less presence of air voids & higher dimension of aggregate have lower density due to higher presence of air voids.

Bulk Density of Aggregate. The Unit weight or bulk density of aggregate is the mass or weight of the aggregate required to fill a container of a specified unit volume. The approximate unit weight of aggregate that is commonly used in normal concrete work is between 1200-1750 kg/m 3 (75-110 lb/ft 3) Bulk Density of Sand
20 mm aggregate density:- density of 20 mm aggregate is 1550 kg/m3, it means 1 cubic metre of 20 mm aggregate weight is 1550 kg. What is the density of crushed aggregate? Most of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m3 (150-181 lb/ft3).
Gravel aggregates There are two types of gravel aggregates: i) Scabbled stone- regular natural or crushed. ii) Gravel - rounded pebbles usually of river or sea origin. Fractions of gravel aggregates are as follows: 3-10 mm, 5-20 mm, 5-40 mm, 20-40 mm. @HASSAN HARRAZ 2017 AGGREGATE STONES 26.
Overview Pike's construction aggregates are locally mined materials used in construction, including stone dust, sand, gravel, crushed stone, and recycled concrete. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications for foundations and french drains, septic drain fields, retaining wall drains, and road side ...
Bulk Density Of Aggregates. Jalal Afsar July 30, 2012 Concrete Strength No Comments. Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense compacted aggregates.
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion ...
