What is Mortar? Who Should Use it, and How is it Used? Here’s All You Need To Know

Mortar is the bonding material between bricks, concrete block, stone, and many other masonry materials. It can be used for above grade and below grade applications. When used properly, mortar can make a structure stronger than the materials it joins together. There are four main types of mortar mix: N (for use in normal, above-grade applications), S (for use in structural applications with heavy loads), M (the most common for general use), and K (for below-grade applications).

Mortar is made by mixing cement, lime, sand, and water in varying quantities to create different strengths of mortar. Some mortars may also contain an air-entraining agent to increase freeze/thaw resistance. Each type of mortar mix has advantages and uses that should be considered before choosing one over the other.

What is Mortar?

Mortar, the “glue” that holds together the bricks, blocks and stones in your project, is a mixture of sand (called fine aggregate) and cement. It may also contain lime, depending on the type of mortar being used. While mortar comes ready-mixed from the store, you can also make your own on site by combining these ingredients yourself, which is called field mixing.

Who Should Use it?

Any contractor or homeowner who has ever tried to mix mortar from scratch knows that it’s back-breaking work and time consuming to boot. For those with large projects or for someone who doesn’t want to spend a whole day mixing, buying pre-mixed mortar may be a better option.

How is it Used?

Whether you’re using mortar on an exterior or interior block or brick wall, you need to know how to use it properly so that it adheres to the surface and dries correctly.

Mortar is a mixture of cement, lime and sand, used in the building trade to hold bricks together. The correct mortar mix ratio will ensure that your project is strong and durable. Because mortar is so important, this blog discusses the basics of mortar mixes in depth.

What is Mortar?

Mortar must be able to hold up the weight of the structure it is holding together and do so for years on end. A good mortar mix should be plastic, durable, and watertight.

Limitations of Brick

Bricks are laid in layers with a bed of mortar between each course. The brickwork by itself would simply crumble without mortar. Bricks are porous and have a low compressive strength. Mortar fills the gaps between bricks to ensure stronger vertical bonds and prevents lateral movement between bricks during settlement or vibrations due to earthquakes or other external forces.

Types of Mortars

The type of mortar mix you use will depend on the application, as each has its own pros and cons:

What is Mortar?

Mortar is a mixture of sand, water, and cement (or other binding materials) that holds or bonds together building materials like bricks, blocks, and stones.

Mortar is a construction material used for bonding masonry materials together in structures. It is sometimes called concrete or cement mortar. The mortar holds the masonry units together and provides the primary support for the structure.

Mortar can be made from different ingredients:

Portland Cement-Lime Mortar

First, let’s look at what mortar is:

Mortar is a mixture of sand, a binder such as cement or lime, and water. It is most often used to hold together bricks, concrete blocks, and stone when building or repairing walls, walkways, patios, and so on. The binder is the “glue” that holds everything together.

Brickwork has held up well for thousands of years because of the strength of its mortar. In fact, mortar is actually stronger than the materials it holds together! With proper mixing and application of mortar, these structures can last for decades with minimal maintenance.

Mortar, the stuff between bricks, is the one of the main components of brick masonry. Mortar is a mixture of sand and cement. A few other ingredients are added to control specific properties in some applications.

Mortar holds bricks together and acts as a filler for the voids within a masonry wall. It can be used for walls above or below grade, but it must be designed for each application. Different types of mortar are mixed to resist water penetration, to provide flexibility to allow for thermal and moisture movement, or to increase bond strength.

Brick masonry walls must have mortar. The amount of mortar is determined by subtracting the volume of all solid materials from the total wall volume (mortar + bricks).

The amount of mortar required will depend on several things:

How much space is inside the wall;

What type of mortar joints you choose (the larger the joint, the more mortar you’ll need); and

How well your mason lays up the wall (a sloppy job will use more mortar).

Mortar is a mixture of sand, cement and water. It is used as a binding agent to hold bricks and blocks together in masonry constructions.

Mortar is widely available ready-mixed and dry-packed, so you can buy the amount you need for your project. For small projects, it’s possible to purchase pre-mixed mortar in bags, but for larger projects, it’s more cost-effective to use mortar delivered by truck.

Mortar must be stored correctly and used within a certain time period after being mixed with water. How long mortar lasts depends on its type; some mortars are fast-setting while others take longer to set.
