I got this question in an online interview.

I would like to ask this question from Source of Aggregates topic in chapter Aggregates and Testing of Aggregates of Concrete Technology

Answer 1

Artificial aggregates are those that are manufactured through mechanical or industrial processes rather than being naturally occurring, such as those obtained from river beds.

So, the correct answer is:

(c) Those who are mechanically obtained

Artificial aggregates are produced from materials like crushed stone, slag, or other industrial by-products and are typically used to enhance the properties of concrete or for specific construction applications
