What is N-type Mortar? Types of Mortars and Their Strengths
Mortar is essential in construction for holding bricks, stones, and blocks together. It provides stability, durability, and resistance against weather. Mortars are categorized into different types based on their strength. This article explains N-type mortar and other common mortar types clearly and simply.
What is Mortar Strength?
Mortar strength refers to how well the mortar can hold together masonry units like bricks and stones. Higher strength mortars provide better support and resistance, whereas lower strength mortars allow flexibility to absorb movement.
Common Types of Mortar and Their Strength
There are four main types of mortars commonly used in construction, classified by their strength from strongest to weakest. They are types M, S, N, and O.
1.M-type Mortar
- Strength: Approximately 2500 psi (17.2 MPa)
- Use: Ideal for foundations, retaining walls, driveways, and heavy structures. It is the strongest type, with high compression strength.
2.S-type Mortar
- Strength: Around 1800 psi (12.4 MPa)
- Use: Good for exterior walls, patios, pavements, and areas exposed to high wind and weather. Balances strength and flexibility well.
3.N-type Mortar
- Strength: Around 750 psi (5.2 MPa)
- Use: General-purpose mortar commonly used in walls, interior construction, and non-load-bearing exterior applications. It provides balanced strength and flexibility, suitable for standard masonry work.
4.O-type Mortar
- Strength: Approximately 350 psi (2.4 MPa)
- Use: Best suited for interior, non-structural walls, and historical renovation work where low compressive strength and high flexibility are desirable.
Choosing the Right Mortar Type
Selecting the correct mortar type depends on the specific use, required strength, and flexibility. Understanding the different mortar types helps ensure your construction project is safe, durable, and cost-effective.
Now that you understand mortar types and their strengths clearly, selecting the right mortar for your next project is easier. For high-quality mortar solutions, reach out to Ningbo Wanhong Ruiquan Technology Co., Ltd.
