Definition

Portland cement is a hydraulic cement produced by pulverizing clinker, consisting essentially of hydraulic calcium silicates, and usually containing one or more forms of calcium sulfate as an interground addition. It is the most common type of cement used in construction.

Purpose

The purpose of Portland cement is to act as a binder in concrete, mortar, and stucco, providing strength and durability to various construction applications.

Examples of Use

1. Concrete Production: Portland cement is the primary ingredient in concrete, used in building foundations, roads, and bridges.
2. Masonry Mortar: Creating strong, durable mortar for bricklaying and block construction.
3. Stucco: Used as a binder in exterior wall finishes for weather resistance.

Related Terms

• Clinker: The raw material in Portland cement, formed by heating limestone and other materials.
• Hydraulic Cement: Cement that hardens upon contact with water, like Portland cement.
• Concrete: A composite material made of Portland cement, aggregates, and water.

Notes

• Portland cement is available in various types, each designed for specific applications and environmental conditions.
• It must be mixed with appropriate proportions of sand, aggregate, and water to achieve desired properties.
