An aggregate blend is composed of 55% aggregate A (Sp. Gr. 2.631), 25% aggregate B (Sp. Gr. 2.331) and 20% sand (Sp. Gr. 2.609). The Sp. Gr. of the blend aggregate is most nearly: a. 2.732
b. 2.545
c. 2.581
d. 2.614

The right choice would be Option b (2.545).

Explanation:

The given values are:

The aggregate blend will be:

= 55%

= 2.631

= 25%

= 2.331

= 20%

= 2.609

Now,

On applying the formula, we get

⇒

On substituting the values, we get

⇒          

⇒          

⇒
