Is Masonry Cement and Mortar the Same
No, masonry cement and mortar are not the same.
While they are both used for building brick or block walls, there are key differences between the two.
Mortar is a mixture of sand and cement, typically portland cement mixed with hydrated lime and fine sand.
It is designed to have lower strengths, retain water for a certain period of time, and have a high air content.
On the other hand, masonry cement is made by intergrinding portland cement with lime or other ingredients to produce high air content in a kiln.
Masonry cement is primarily used for making mortar and can include an air-entraining agent or a water-repellent additive.
So, while they are related, masonry cement and mortar are not the same.
Did You Know?
1. Masonry cement and mortar are not the same things. Masonry cement is a special type of cement that is used to bind bricks and other masonry units together, while mortar is a mixture of cement, sand, and water used for the same purpose.
2. It is believed that the construction of the Great Wall of China relied heavily on the use of mortar, which allowed for the intricate interlocking of stones and bricks to create a strong and durable structure.
3. In ancient Egypt, mortar was used not only for construction purposes but also for cosmetic ones. Egyptians would mix mortar with various pigments to create colorful makeup known as “kohl,” which was used to emphasize the eyes.
4. The Romans were known for their advanced techniques in masonry and mortar. Their innovative use of volcanic ash known as “pozzolana” greatly improved the strength and durability of mortar, and many ancient Roman structures are still standing today.
5. Mortar has been used for centuries as a form of graffiti. In Pompeii, the ancient Roman city destroyed and preserved by the eruption of Mount Vesuvius, there are numerous examples of walls covered in graffiti made by mixing mortar with charcoal, ashes, or other materials to create a durable and lasting form of expression.
Mortar Vs. Concrete: Understanding The Difference
Mortar and concrete are key building materials, serving different purposes. Mortar is a mixture of cement and sand, specifically used for constructing brick or block walls. On the other hand, concrete is renowned for its immense strength and is employed for heavy-duty applications. The distinction between the two lies in their composition and intended use. Understanding these differences is crucial to guarantee the successful completion of any construction project.
Making Mortar: Ingredients And Process
Mortar can be produced by mixing various ingredients, providing different properties based on the specific requirements of the project. One common method involves blending portland cement with hydrated lime and fine sand. The addition of lime enhances the workability and the ability of the mortar to bond with the masonry units. Another method involves using masonry cement, which is created by intergrinding portland cement with lime or other ingredients. This process leads to the production of masonry cement with high air content in a kiln, ensuring improved workability.

Types Of Mortar And Their Strengths
Mortar comes in different types, each tailored to meet the needs of specific construction projects. Three widely produced types of mortar are Types M, S, and N, each with varying levels of compressive strengths. Type M mortar possesses an impressive compressive strength of 2500 pounds per square inch (psi), making it ideal for load-bearing structures. Type S mortar, with a compressive strength of 1800 psi, is commonly used for below-grade walls or walls carrying heavy loads. On the other hand, Type N mortar, which has a compressive strength of 750 psi, is sufficient for non load-bearing walls.
- Type M mortar: 2500 psi, ideal for load-bearing structures
- Type S mortar: 1800 psi, suitable for below-grade or heavy load walls
- Type N mortar: 750 psi, sufficient for non load-bearing walls

Choosing The Right Type Of Mortar For Your Project
Selecting the appropriate type of mortar is crucial to ensure the success and longevity of a construction project. The choice of mortar should consider factors such as the purpose of the wall, the load it will bear, and the specific requirements of the project. For non-specification work, Type S mortar is the most commonly used option. It offers a good balance of strength and workability. Type N mortar is typically used for non-load-bearing walls, as it provides adequate strength for such applications. It is important to consult with professionals or follow building codes and specifications when determining the type of mortar to use.
Masonry Cement And Water-Repellent Additives
Masonry cement is a key component in mortar production and plays a vital role in enhancing the properties of the mixture. It is primarily used for making mortar and can include either an air-entraining agent or a water-repellent additive.
The addition of an air-entraining agent allows mortar to withstand the effects of freezing water, preventing damage and ensuring durability.
Conversely, a water-repellent additive is used to create waterproof cement, referred to as portland cement with a water-repellent agent incorporated. This type of cement is ideal for applications where resistance to water penetration is necessary.
While mortar and concrete both use ingredients such as cement and sand, they serve different purposes in construction. Mortar is specifically designed for brick and block walls, providing bonding strength and enabling easier repairs.
The wide range of mortar types allows for versatile applications, as each type offers varying levels of strength.
When choosing the right mortar for a project, it is important to consider factors such as load-bearing requirements and the specific purpose of the wall.
Masonry cement, with its air-entraining and water-repellent additives, further enhances the performance and longevity of mortar.
Understanding the distinctions between masonry cement and mortar is essential for the successful execution of any construction endeavor.

Frequently Asked Questions
Can you use masonry cement as mortar?
Yes, masonry cement can be used as mortar. Masonry cement is made by blending portland cement, hydrated lime, and various additives specifically designed to enhance its performance as mortar. When combined with fine sand, masonry cement creates a strong and durable bond between bricks, stones, or other masonry materials. While the traditional method of making mortar with portland cement and hydrated lime is still commonly used, the use of masonry cement provides an alternative that is specially formulated for masonry applications.
What is a masonry cement?
Masonry cement is a specialized type of cement that is primarily used in mortar. It is created by blending portland cement with ground limestone or other additives, as well as incorporating either an air-entraining agent or a water-repellent additive. The addition of these ingredients enhances the durability and performance of the cement when used in masonry applications. This specialized cement is particularly useful in construction projects where mortar that offers water resistance or improved workability is required.
What is the difference between cement and masonry?
Cement and masonry, although both durable, differ in their composition and construction process. Cement is a factory-prepared mixture of different elements, while masonry is created on-site using bricks and mortar. The main distinction lies in how they are formed – concrete is poured into molds, whereas masonry involves the joining of bricks and mortar to construct walls or structures. So, while cement serves as the primary ingredient in concrete, masonry refers specifically to the construction technique using bricks and mortar.
Are masonry and mortar cements different than standard concrete cements?
Yes, masonry and mortar cements differ from standard concrete cements. Although they all share cement as a component, the composition and purpose vary. Masonry cement combines plasticizers and air-entraining agents to improve workability and freeze-thaw resistance, making it suitable for constructing brick and stone structures. On the other hand, mortar cement includes lime aggregate, enhancing the adhesive properties for bonding bricks or blocks together. While standard concrete serves as a primary material due to its durability and strength, masonry and mortar cements complement construction projects by providing specific characteristics tailored for bonding and masonry work.
