Mortar is a general term for a mixture of cement, sand and gravel that is used as the binding agent in bricklaying. It has been used for thousands of years and it’s essential for the creation of brick walls.
In this article, we explore four types of mortar and their properties: traditional mortar, hydraulic lime mortar, cement mortar and synthetic mortars.
We also discuss how these different types of mortar are used in construction work.
What is Mortar Composed of and What is it Used For?
Mortar is a construction material composed of a binder, usually cement, and various aggregates, such as sand, gravel, or limestone.
It is used for bonding bricks, stones, and other masonry units together in the construction of walls and other structures.
Mortar can be either dry-mixed or wet-mixed. In the dry-mix process, all of the ingredients are blended together in their dry state and then water is added to create a slurry that can be applied to the masonry units.
In the wet-mix process, water is added to the dry ingredients prior to application.
The type of mortar you use will depend on the project you are working on and the materials you are using.
For example, if you are working with brick, you will need to use a different type of mortar than if you were working with stone.
The properties of mortar can also be altered by adding different chemicals to the mix.
The most important property of mortar is its compressive strength, which is determined by the ratio of cement to sand in the mix.
The higher the ratio of cement to sand, the stronger the mortar will be. Other important properties include workability.
Uses for Mortar
Mortar can be used to bond bricks, stones, tile, or concrete pavers together to create retaining walls and other landscape features such as patios and walkways.
It’s also commonly used to hold bricks in place along the outside wall line of a house where the siding ends and the gutters begin.
What are the Different Types of Mortar?
Types of Mortar
- Cement Mortar
- Lime Mortar
- Surki Mortar
- Gauged Mortar
- Mud Mortar
Type of Mortar – 1. Cement Mortar
There are many types of mortar, but the most common type is cement mortar. Cement mortar is made by mixing cement and sand in a 1:3 ratio. This type of mortar is very strong and durable. It is often used for construction projects that require a high level of strength, such as building foundations.
Cement mortar can be mixed by hand or using a machine. If you are mixing by hand, you will need to use a spade or hoe to mix the ingredients together. If you are using a machine, you will need to use a concrete mixer.
Once the cement and sand are mixed together, water is added to create a slurry. The amount of water added will vary depending on the type of cement being used. Once the water is added, the mixture is stirred until it reaches a creamy consistency.
Once the mortar is mixed, it can be used immediately or stored in a cool, dry place for later use. If you are storing the mortar, be sure to keep it covered so that it does not dry out.
Cement mortar is a very versatile material. It can be used for construction projects of all sizes, from small repairs to large buildings.
Type of Mortar – 2. Lime Mortar
Lime mortar is a traditional type of mortar. It has been used for centuries in construction. Lime mortar is very strong and durable. It is also flexible, which makes it ideal for use in buildings that are subject to movement, such as earthquake-prone areas.
Lime mortar is also breathable. This means that it allows moisture to pass through it, which helps to keep buildings healthy and free from Mould and damp.
Lime mortar can be mixed by hand or using a machine. It should be mixed slowly and carefully to avoid getting it too wet or too dry. The ratio of lime to sand should be about 1:3 for most applications.
Once mixed, lime mortar can be used immediately or left to cure for a period of time before use. Curing time will vary depending on the conditions (temperature, humidity etc.) and the type of mortar used. Generally, lime mortar should be allowed to cure for between 3 and 6 weeks before use.
Lime mortars provide less strength than other forms of mortar, so they are best suited to either unreinforced walls or decorative works that don’t require great strength (such as a stone-topped garden wall).
Lime mortar is also more difficult to lay than cement or concrete mortar, since it must be kept damp during application.
This can make it harder to control the rate of application, especially if you are working on your own.
It is important that lime mortar does not dry out too quickly once applied, otherwise it will not have time to harden properly.
You should always use a damp application, to ensure that the mortar stays workable and mixes well.
Type of Mortar – 3. Surki Mortar
Surki mortar is a type of mortar made from burnt clay. It is commonly used in construction in India and Pakistan. Surki mortar has a number of advantages over other types of mortar.
One advantage of surki mortar is that it is very strong. This means that it can be used to construct buildings that are very tall and/or have heavy loads placed on them. Surki mortar is also fire resistant, which makes it ideal for use in buildings that are at risk of fire.
Another advantage of surki mortar is that it is easy to work with. This means that construction workers can lay bricks quickly and easily when using this type of mortar. Surki mortar also dries quickly, which means that construction projects can be completed more quickly when using this type of mortar.
Disadvantages of surki mortar include the fact that it is not weather resistant. This means that buildings constructed with this type of mortar may suffer from weather damage over time. Surki mortar is also not as widely available as other types of mortar, which may make it more expensive to purchase.
Despite its disadvantages, surki mortar is still a popular choice for construction in India and Pakistan due to its many advantages.
Type of Mortar – 4. Gauged Mortar
Gauged mortar is a type of mortar that has been mixed with an additive to make it denser. This additive can be either Portland cement or lime.
Gauged mortar is typically used for masonry work that requires a strong bond, such as bricklaying.
It is used in building walls and foundations.
The additive used to make the mortar denser is usually clay. As the mix dries and hardens, it shrinks, so if the additive were not added to the mixture, the bricks would fall out of their joints as they dried and hardened.
The addition of sand to the mortar softens its consistency and reduces shrinkage.
Gauged mortar is also used in building rubble walls. In this method, the bricks are laid out in a pattern, but they do not touch each other until they have cured and dried.
The bricklayer then adds gauged mortar to fill in all the spaces between the bricks.
This type of construction is widely used in tunneling projects because it allows for the creation of arches by supporting them with rubble.
Gauged mortar is also used in some buildings because it enables the wall to accommodate any expansion or contraction that occurs.
Type of Mortar – 5. Mud Mortar
Mud mortar is a type of mortar that is made from a mixture of mud, water, and straw. It is commonly used in construction in many parts of the world.
Mud mortar is very easy to make. All you need is some mud, water, and straw. You can find all of these ingredients in most construction sites.
Mud mortar is very strong and durable. It can be used to build both walls and floors. Mud mortar is also fire resistant.
Mud mortar is a very cheap type of mortar. It is also environmentally friendly because it does not use any cement or other man-made materials.
Overall, mud mortar is a great choice for construction projects. It is cheap, durable, and environmentally friendly.
How to Mix a Basic Mortar Mix?
One of the most important things to know when it comes to working with mortar is how to mix it correctly.
If you don’t get the mixing ratio right, then your mortar will be either too weak or too strong, which can cause all sorts of problems down the line. So, what’s the correct way to mix a basic mortar mix?
First of all, you’ll need to gather together the following ingredients: cement, sand, water, and lime (if using).
The amount of each ingredient you’ll need will depend on the type of mortar you’re making and the job you’re using it for – so be sure to check your recipe or instructions carefully.
Once you have your ingredients, it’s time to start mixing. Begin by adding a small amount of water to your mixing container and then slowly add in the cement until it’s all incorporated.
Next, add in the sand and mix everything together until it’s a consistent color and texture. Finally, add in the lime (if using) and mix once again until everything is combined.
And that’s it! Once you’ve mixed everything together well, your mortar is ready to use. Be sure to use it within a few hours of mixing for the best results. Now go forth and build!
How to Choose the right Mortar for Your Building Project?
When it comes to choosing the right mortar for your building project, there are a few things you need to take into account.
The type of mortar you choose will be determined by the job at hand. For example, if you are doing a repair job, you will want to choose a different type of mortar than if you were doing new construction.
Here are a few tips on how to choose the right mortar for your project.
The first thing you need to consider is the type of bricks or stones you will be using. Different bricks and stones have different absorption rates.
This means that some bricks and stones will absorb more water than others.
If you are using bricks or stones with a high absorption rate, you will need to use a mortar with a higher water content.
Conversely, if you are using bricks or stones with a low absorption rate, you will need to use a mortar with a lower water content.
Another thing to consider is the climate in which you will be working. If you are working in an area with high humidity, you will need to use a different type of mortar than if you were working in an area with low humidity.
In general, mortars with higher water contents do better in humid climates while mortars with lower water contents are better in dry climates. The type of brick or stone you are using can also change the mortar that you use.
For example, if you are working with fire brick, you will need to use a formula that will not leach any moisture out of the brick.
The same goes for stone with high absorption rates.
If you have any doubt as to which mortar is best for your project, consult your local hardware store and ask for a recommendation from their staff.
Properties of Good Mortar
Mortar is a construction material made of a mixture of cement, sand, and water. It is used to bind together bricks or stones in masonry construction.
A good mortar should be strong, durable, and easy to work with. It should also have a low shrinkage rate so that it doesn’t crack over time.
To ensure these properties, the cement, sand, and water must be properly proportioned and mixed together thoroughly. Proportions of Mortar.
To make mortar, a general ratio of 3:2:1 is used. This means that for every three parts of sand, two parts cement, and one part water are mixed together.
The mixture should be thoroughly mixed so that there are no dry areas or pockets with little or no cement in them. It’s all about mixing!

FAQs on Mortar
What is a mortar used for?
Mortar mixes cement with either sand or gravel to form a paste that can be used as a binder to hold bricks, blocks, and stone together in structures.
They are used for both interior and exterior work, but typically used on the inside of a building. This can include the infill between structural and non-structural walls and partitions.
Mortars are primarily used to construct and fill holes or cracks between bricks, blocks, stones and other materials. This is also used for plastering walls and as an adhesive.
What is the difference between cement and mortar?
Mortar is made of Portland cement and sand. The ratio can be anywhere from 1:3 to 1:6 (cement to sand).
When mixed with water, the two are combined and bind together, becoming a dense mass that hardens with exposure to air or water.
Mortars consist mostly of Portland cement and sand. In some cases, additives such as lime may also be added for qualities such as rapid set or physical strength.
Is mortar just cement and sand?
Yes, mortar is just a mixture of cement, water and sand. Cement and sand are two separate entities but if you mix them up together with water it creates a paste called mortar.
These two items react chemically together to harden and bind to create the material mortar.
