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
2. The surface characteristics of aggregate affects the workability of fresh mass & the bond between the aggregate & cement paste in hardened concrete. If it is rough, workability decreases & bond increases. 3. The grading of aggregate affects the workability, density & economy. 4. The amount of aggregate in unit volume of concrete

The tolerance for acceptance on fresh density is typically ±3 lb/ ft3 (±50 kg/m3) from the target value. Lightweight aggregates must comply with the requirements of ASTM Specification C 330. Due to the cellular nature of lightweight aggregate particles absorption typically is in the range of 5% to 20% by weight of dry aggregate.
A well graded granular material. Suitable for roads/sites for moderate depth excavations (up to approximately 200mm). Requires a minimal amount of blinding to obtain a smooth finish. 70 – 125mm. A uniformly graded granular material which compacts well to give a very sound surface. The most commonly used hardcore for roads, sites and foundations.

The density of sand (fine aggregate) is ranging between 1450-2082 kg/m3 depending on different conditions like wet, dry, loose, dry-packed, and wet packed. What is 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.
In selecting aggregates for concrete, then, it may be laid down as a general rule that those should be chosen which give the greatest density. If it is practicable to mix two materials, as sand and gravel, the proportion which gives the great est density should be determined by experiment, and rigidly adhered to, whatever may be the proportion ...
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.
Coarse Aggregate Content. Using the coarse aggregate content table with the given nominal maximum aggregate size of 37.5 mm (1.5 inches) and the given fine aggregate fineness modulus of 2.80, the recommended volume fraction of coarse aggregate is 0.71. This means that the coarse aggregate should occupy 71 percent of the total volume. However, this volume of aggregate includes the …

performance record, the aggregates should be tested before they are used in concrete.

Aggregates of expanded shale,
Nov 26, 2009· As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs. per cubic foot. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used.
Jul 22, 2020· Minimum Thickness of Concrete Columns. A column is defined as having a section depth no more than 4 times its width, and the height is a minimum of 3 times the section depth. Concrete columns tend to be specified as a minimum cross-sectional size (i.e. 225mm x 225mm is the minimum size) rather than a minimum depth, as they are vertical elements.
Mar 16, 2012· The density varies (from about 0.25 t/cu m to 2.4 t/cu m, and beyond) with type and constituency of the aggregate: The most commonly used aggregates have a density of 2.2 to 2.4 t/cu m Aggregates ...
