Cement

Definition

Cement is a calcined lime binder used in construction that sets, hardens, adheres, and joins other materials together. It usually refers to Portland cement, which forms concrete when mixed with sand, gravel, and water.

Purpose

The purpose of cement is to act as a binding agent in construction, providing the necessary adhesive properties to hold materials like bricks, stones, and aggregates together, forming strong and durable structures.

Examples of Use

1. Concrete Mixing: Cement is the key ingredient in concrete, used for constructing buildings, bridges, and other infrastructure.
2. Mortar: Used in masonry work to bond bricks and stones.
3. Plastering: Creating smooth, durable surfaces on walls and ceilings.

Related Terms

• Portland Cement: The most common type of cement used in construction.
• Hydraulic Cement: Cement that sets and hardens by chemical reaction with water.
• Lime: A component often mixed with cement to improve workability and durability.

Notes

• Proper curing of cement-based products is essential to achieve maximum strength and durability.
• Cement must be stored properly to prevent moisture absorption and degradation.
