SPECIFIC GRAVITY AND ABSORPTION OF COARSE AGGREGATE

Coarse aggregate specific gravity and absorption for mineral aggregates used in asphaltic concrete, other than asphaltic concrete friction course, shall be determined on Plus No. 4 Material 1.3 This test method may involve hazardous material, operations, or equipment.

What are the limits of water absorption of coarse aggregate?

Oct 28, 2018 · Limits of water absorption of coarse aggregate ,practically are not fixed it may vary depending on climatic condition . Limits if WA are different for different purpose and overall it varies from 0.3 - 2.5% . It is capacity of absorption of aggregates when it is contact with water for a long period.

How Coarse Aggregate Affects Mix Design of Concrete?

Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture.

ASTM C127 - 15 Standard Test Method for Relative Density ...

1.1 This test method covers the determination of relative density (specific gravity) and the absorption of coarse aggregates. The relative density (specific gravity), a dimensionless quantity, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as apparent relative density (apparent specific gravity).

Sp. Gravity & Water Absorption Of Coarse Aggregate ...

The object of the experiment is to determine the Specific Gravity & Water Absorption of Coarse Aggregate. Specific Gravity is the ratio of the mass of unit volume of aggregate at a stated temperature to the mass of the same volume of gas free distilled water at a stated temperature.

Specific Gravity of Coarse Aggregates: Its Importance ...

As per the definition given in the ‘IS: 2386 (Part III) – 1963’, (Indian Standard- Methods of Test for Aggregates for Concrete – Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregate particles.

Coarse Aggregate: Definition & Density - Video & Lesson ...

Coarse aggregate absorption is the moisture content, or amount of water, in the coarse aggregate when the aggregate is fully saturated with a dry surface.

Maximum range of absorption capacity of fine aggregate (sand)

The absorption looks very high, if it is sand is it a river sand or Sahara sand. It could be lightweight (low density), as low density aggregates has relatively high absorption capacity. A careful...
