Question

The average specific gravity of natural aggregate 1 point



a.1.5



b.2.7



c.3.15



d.2.1

Answer 1

Specific gravity of fine aggregate (sand) is the ratio of the weight of given volume of aggregates to the weight of equal volume of water. The specific gravity of sands is considered to be around 2.65.

So the correct answer is optional (B)

Answer 2

The average specific gravity of natural aggregate is 2.7 (Option B)

• The bulk of natural aggregates have a specific gravity between 2.6 and 2.8.
• The specific gravity of aggregates used in construction typically ranges from around 2.5 to 3.0, with an average value of about 2.68.
• The specific gravity of fine aggregate (sand) is the weight of a particular volume of aggregates divided by the weight of an equivalent amount of water.
• As a result, option B is the correct answer.
