What Is A Mortar? Why Do You Need To Know This Before Constructing A Building

It’s very essential to be informed about a thing before using it right? Without due information about it, things could lead to failure. There is a tendency to mishandle things when we don’t read first about them. How do we know that we are reading the right materials?

Check that the sources are reliable. Then, scan the information and analyze how the information is laden. For example, if you are planning to use this thing for this thing, the information you get should be exact. Articles can help you give that information, no matter how specific you want it to be.

Plus, articles are fun to read and not boring. Also, it’s informative and usually short unlike other media. The only thing you have to remember is hitting the right keyword on the internet (if you’re using the internet) to get the most detailed information. Article reading is fun, and very informative.

How do we know what kind of material we are using in constructing a building? How do we know what’s best to use and what’s not? Of course, we will know if we can identify and differentiate each from the others.

Have you ever planned constructing a building and you don’t know what types of substances to use? Worry not, I will provide you the easiest explanation of these materials.

This article will help you know what mortar is and when and where it is best to use. Knowing what a mortar is and how it differs from other materials will improve your work in constructing a building.

What are the Different Kinds of Mortar?

Mortar is a paste used to bind building chunks such as bricks, stones and concrete units. It is also used to seal the uneven gaps and other times add colors, patterns and others walls. In a more specific sense mortar includes asphalt, clay and soft mud.

Cement Mortar

Cement mortar becomes solid when it cures, resulting in a stiff aggregate structure. Mortar is easier and less expensive to repair than the other building block that’s why it is intended to be weaker and becomes the weakest element in masonry.

Ordinary Portland

In 1794, Ordinary Portland cement mortar was invented by mixing aggregate, water and Ordinary Portland cement.

It was invented as a result of efforts to create stronger mortars. The advantage of Portland cement is that it turns hard and quickly which results into a faster construction.

Buildings built with lime mortar has the flexibility, breathability and softness of the lime mortar that’s why as a common rule, Portland cement should not be incorporated for its repointing or repairing.

Lime mortar

Lime mortar is more lenient than cement mortar and is very flexible to adjust to changing conditions such as ground shifting. Cement mortar allows flexibility and is harder. If these mortars are existing in a wall it can cause brickwork to crack.

Lime mortar allows moisture to easily evaporate and move through from the external part of the wall. In buildings there are cracks that can be found allowing rain to enter into the building.

Because of the breathability of the lime mortar, the moisture is freely allowed to evaporate, thus not allow the wall to be wet. Repairing, rendering and repointing an old wall with cement mortar stops the process of evaporation, as what have explained earlier. It causes problems related with moisture in the cement.

Pozzolanic Mortar

Another type of mortar is Pozzolana, a sand and fine ash. This mortar was learned by the Romans that when lime mortar is added to pozzolana, the lime sets quickly even under the water.

The four kinds of pozzolana are in different colors: black, grey, red and white. Pozzolana became a general term since then, for aluminous additives.

Firestop Mortar

Firestop mortar is a combination of mixed water and powder, forming a cementatious stone that eventually dries hard. It is sometimes mixed with lightweight aggregates, such as vermiculite and perlite. It is also pigmented to distinguish it from generic materials for the reason that unlawful substitution should be avoided.

Firestop mortars are typically used to firestop openings in walls and floors, and are also inert fire protection substances. These mortars differ in properties and formulas from other cementatious substances. It cannot be substituted with other mortars especially generic.

What are the Differences among Cement, Concrete and Mortar?

Cement is the binding element in both mortar and concrete.

Concrete’s a product composed of sand, gravel and cement or other coarse substance. The cement is activated when water is mixed with concrete. Concrete is the element responsible for the mix to form one dense object.

Mortar, on the other hand is a product composed of sand cement. The cement is also stimulated when water is mixed with mortar. However, concrete can stand alone whereas mortar cannot because it holds stones and bricks together.

Thus, cement mixing refers to using cement in the mixing of mortar or concrete. While mortar, on the other hand, is used between bricks in brick patios.

Did you learn from this article? I highly hope that you do and you can now identify which material to use when constructing a building, even on repairing or repointing one.

Remember that you can’t just use this type of mortar whenever you like to. Think of the possible consequences when deciding what to use.

Now that everything is noted, I hope that it is useful for you and your future endeavors in building constructions. If you have further questions about mortar and its types, write your comment and I am open for suggestions. If there would be a time when you get confuse again, just think of the vivid points I made in this article about mortars.
