What is a granular material such as sand, gravel, or crushed stone that can be fine or coarse?

Question:

Which of the following is a granular material such as sand, gravel, or crushed stone that can be fine or coarse?

a) Aggregate
b) Cement
c) Slurry
d) Mortar

Answer:

The granular material, which can be fine or coarse and is made up of sand, gravel, or crushed stone, is known as 'aggregate'.

Explanation:

The granular material described in the question which can be made of sand, gravel, or crushed stone and can vary from fine to coarse, is referred to as aggregate. It's one of the three primary components used in the construction of concrete, alongside water and cement. The term aggregate can be used to define material in a broad range of sizes, from small granules to large boulders, depending on its purpose.

By using this constituent along with water & cement, we can generate a paste that binds the aggregate and forms a strong, durable, and malleable building material known as concrete. The additional information given about sedimentary rock seems to be a separate topic. Sedimentary rock is typically formed over time by the natural processes of weathering and erosion, and not by human activity.
