# Mortar: The Essential Building Material
Mortar is a versatile construction material used to bind bricks, stones, and other masonry units together. Composed of a mixture of cement, sand, water, and sometimes lime, mortar provides structural stability, weather resistance, and adhesion in masonry work.
## Types of Mortar
1. Cement Mortar – Made from cement and sand, offering high strength and durability.
2. Lime Mortar – Contains lime and sand, providing flexibility and breathability, often used in historic restorations.
3. Gypsum Mortar – Quick-setting and used primarily for plastering.
4. Polymer Mortar – Enhanced with polymers for improved resistance to chemicals and water.
## Uses of Mortar
– Bonding bricks or blocks in walls
– Plastering surfaces for a smooth finish
– Repairing cracks and joints in masonry
– Setting tiles in flooring and walls
## Key Properties
– Workability – Easy to spread and shape
– Adhesion – Strong bonding with masonry units
– Durability – Resists weathering and compression
Mortar remains a fundamental component in construction, ensuring the longevity and stability of structures. Proper mixing and application are crucial for optimal performance.
