Expert Solution

Step 1

Concrete

Concrete is a composite material used in engineering that closely resembles rock in its physical characteristics. It is merely a combination of aggregates, typically made up of crushed rock or sand. When a structure is being built, concrete is used to give strength, durability, and versatility. After water, concrete is the second most common substance used worldwide.
