What Is Type N Masonry Cement? Ultimate Explanation
For bonding bricks and other types of masonry units, masonry cements are used. There are different types of masonry cement can be found and type N masonry cement is one of them. The type of masonry cement differs in different mixing ratios.
Generally, type N cement is used for exterior and above-grade walls. And this type of mortar cement is suitable for severe weather and high heat. If you are willing to learn everything about type N mortar cement then this article can be of help.
In today’s article, we have discussed what is type N masonry cement, where it is used, its advantages, disadvantages, and so on. So, be with us till the end and learn everything about the type N masonry cement. Let’s begin then.
What Does Type N Masonry Cement Mean?
When it comes to masonry cement, there you will find four types of masonry cement such as M, N, O, and S. Each type of masonry cement has a different mixing ratio and is used for different types of masonry.
Among them, type N masonry can be described as a general-purpose mortar mix. For preparing type N masonry cement, a 1:1:6 ratio is followed. With 1 part of Portland cement, 1 part limestone, and 6 parts sand is added, and then with water, the masonry cement is prepared.
It has medium compressive strength, after curing for 28 days, it can achieve a compressive strength of about 750 to 900 psi.
Where Type N Masonry Cement is Used?
Type N masonry cement is used for different working places. It can be used for interior walls and exterior walls. Can be used in above-grade masonry such as brick walls, concrete block walls, and so on. Also, if you are working with soft stone masonry, there you can use type N masonry cement
Physical Properties of Type N Masonry Cement
After gathering ideas about what type N masonry cement is and its usage area of it, now let’s find out its physical properties of it.
| Parameters | Type N Masonry Cement | |
| Fineness, residue on a 45-um sieve max., 35% | 24% | |
| Initial Setting Time | 2 hours | |
| Final Setting Time | 24 hours | |
| Compressive strength | At 7 days | 500 psi |
| At 28 days | 900 psi | |
| Air Content | Minimum | 8% |
| Maximum | 21% | |
Advantages and Disadvantages of Using Type N Masonry Cement
Type N masonry cement is a versatile masonry cement that can be used for different types of masonry work. This masonry cement has both advantages and disadvantages. Here we have provided the pros and cons of it. Let’s find out then.
ADVANTAGES
- It has a decent compressive strength that is sufficient for most general-purpose masonry work.
- Lesser air content.
- Has better water retention which helps to prevent the cement from drying out quickly.
- Can withstand severe weather and higher temperature environment.
- Has a decent workable consistency with durability.
DISADVANTAGES
- Can’t use in every type of application.
- Compared to S, and M masonry types, it has lesser compressive strength.
- Higher initial setting time compared to other types of masonry cement.
- Has maximum air content.
FAQs (Frequently Asked Questions and Answers)
What is the difference between type S and Type N masonry cement?
The major difference between type S and type N is, type S has higher compressive strength than type N masonry cement. Another difference is, type S masonry mortar has more field of application than type N masonry cement.
Is Type N masonry cement the same as Portland cement?
No, type N masonry cement isn’t the same as Portland cement. A portion of Portland cement is used for preparing type N masonry cement.
Is quikrete a Type N mortar?
Yes, quikrete is a type N mortar. It was designed to meet ASTM (American Society for Testing and Materials) C 270 for type N mortar. It can achieve compressive strength of up to 750 psi.
Conclusion
To sum up, if you are looking for masonry cement with medium compressive strength then type N will be the best choice for you. With lower settings time and moderate strength, you can use it for exterior, interior masonry work with ease.
