Concrete

Definition

Concrete is a composite material consisting of a binding medium (usually portland cement and water) within which particles or fragments of aggregate (such as sand and gravel) are embedded.

Purpose

The purpose of concrete is to provide a versatile, durable, and strong building material suitable for various construction applications, from foundations and slabs to bridges and roads.

Examples of Use

• Concrete is used in the construction of residential and commercial building foundations and floors.
• It is employed in infrastructure projects such as highways, bridges, and dams.
• Precast concrete elements, such as beams and panels, are manufactured for use in building construction.

Related Terms

• Portland Cement: The primary binder used in concrete, made from limestone and clay.
• Aggregate: Particles such as sand, gravel, or crushed stone, mixed with cement to create concrete.
• Reinforced Concrete: Concrete that is strengthened with embedded steel bars or mesh.

Notes

Concrete must be properly mixed, placed, and cured to achieve its desired properties. The proportion of ingredients and the quality of materials significantly influence the strength and durability of the final product.
