What is concrete made of and how does it benefit to society?

Answer 1

Concrete is composed of cement mixed with aggregrate (which is usually made of gravel, limestone, or granite combined with sand), water, and chemical admixtures.

Concrete is used to make pavements, pipe, architectural structures, highways, roads, foundations, bridges/overpasses, as well as footing for walls and fences.

The concrete industry is a $35 billion industry which employs an average of two million workers just in the United States. Over 50,000 miles of highways are paved with this stuff.

Answer 2

Concrete is made of a mixture of cement, water, and aggregates like sand, gravel, or crushed stone. It benefits society by providing a durable, versatile, and cost-effective construction material that is widely used in building infrastructure such as roads, bridges, buildings, and dams. Concrete also has a long lifespan and is energy-efficient due to its thermal properties.
