SPECIFIC GRAVITY AND ABSORPTION OF COARSE AGGREGATE
The specific gravity may be expressed as bulk oven dry (OD) specific gravity, bulk saturated surface dry (SSD) specific gravity, or apparent specific gravity. The bulk (SSD) specific gravity and absorption are based on aggregate after 15 to 19 hours soaking in water. This method is not intended to be used with lightweight aggregate. 1.2 The specific gravity and absorption of coarse aggregate ...
SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85
COARSE AGGREGATE AASHTO T 85 GLOSSARY Absorption: The increase in weight due to water contained in the pores of the material. Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume of gas-free distilled water at the stated temperature. Bulk SSD Specific Gravity ...
Coarse Aggregate: Definition & Density - Video & …
30.11.2017 · 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. This indicates the …
SPECIFIC GRAVITY AND ABSORPTION OF COARSE AGGREGATE …
The aggregate is considered “dry” when it has been maintained at a temperature of 110 ±5°C (230 ±9°F) for sufficient time to remove all uncombined water. Saturated Surface Dry (SSD) – condition of an aggregate particle when the permeable voids are filled with water, but no water is present on exposed surfaces. Specific Gravity – the ratio of the mass, in air, of a volume of a ...
How to calculate cement, sand and coarse …
Wet Volume of concrete = Dry Volume of concrete + 55% of dry volume of concrete or. Wet Volume of concrete = Dry Volume of concrete x 1.55. So whatever volume we get from the above formula, we need to multiply the value with 1.55%. Now back to the calculation, Sum of total parts = 1+1.5+3 = 5.5 Parts . Volume of concrete = (1 Cement Part)/5.5 + (2 Sand Part)/5.5 + (4 Coarse Aggregate Part)/5.5 ...

Aggregates - Types of Aggregates | Coarse …
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)
Density of Coarse Aggregate - GharExpert.com
Coarse Aggregate in general should consist of natural occurring stones (crushed, uncrushed or broken), riverbed single or pit gravel. It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent coatings and injurious amounts of disintegrated pieces, alkali, vegetable matter and other deleterious substances. River gravels make the best coarse aggregate. Angular ...
