What Does Mortar Do?

Published in Construction 2 mins read

Mortar is a construction material used to bind building blocks together, such as bricks, stones, or concrete blocks. It acts as a glue that holds the blocks in place and creates a strong, stable structure.

Key Functions of Mortar:

  • Bonding: Mortar provides a strong adhesive bond between building blocks, ensuring the structure remains intact.
  • Support: Mortar supports the weight of the building above it, distributing the load evenly across the structure.
  • Flexibility: Mortar allows for slight movement and expansion of the building materials, preventing cracking and damage.
  • Weather Resistance: Mortar protects the building from water damage by sealing gaps and cracks.

Types of Mortar:

Mortar is available in different types, each suited for specific applications.

  • Type M: Strongest mortar, ideal for high-load bearing walls and foundations.
  • Type S: Strong mortar, suitable for load-bearing walls and exterior applications.
  • Type N: General-purpose mortar, suitable for most residential construction.
  • Type O: Low-strength mortar, used for interior walls and non-load-bearing applications.

Practical Insights:

  • Mortar is typically made by mixing cement, sand, and water.
  • The ratio of these ingredients determines the strength and properties of the mortar.
  • Mortar should be applied evenly and consistently to ensure a strong bond between building blocks.
  • It is crucial to use the correct type of mortar for the specific construction project.
