You don’t build a house everyday, therefore, it is crucial that you build it right and strong when you do. And when quality and strength are in the question, cement mortar cannot stay out of it. As yet another basic building material, the right mortar and its efficient application are paramount.
From shock absorption such as in an earthquake to water seeping problems, the right building materials can rule them all out and make your stay in your new house a pleasant one. So, follow along to find out everything about mortar for your construction.
Composition of Cement Mortar
A mortar is a uniform mixture of cement, sand, and water. In masonry construction, many types of mortars are used depending on their applications, binding materials, strength, bulk density, and purposes.
Cement mortar is also an excellent medium for creating a smooth surface on brick or other masonry walls.
Uses of Cement Mortar
Mortar is indispensable for any kind of construction work. The following are some of the many applications of it in construction.
- Mortar is used to hold bricks or stones together in brick or stone masonry.
- It is used to provide a soft, even bed between different levels of brick or stone masonry in order to distribute pressure evenly over the bed.
- It is used to fill the gaps between bricks or stones in order to make walls tighter.
- It is used as a matrix in concrete.
- It is used in plastering to conceal joints and improve aesthetics.
- It is used for moulding and decorative purposes.
Properties of a Good Mortar: Choose the Best
It is always preferable to choose the best mortar when building. As a result, the properties of a good mortar must be researched. In general, good mortar has the following characteristics:
- The basic characteristic of mortar should be adherence. A good mortar should stick well to construction units (bricks, Stones etc).
- The mortar should be watertight. It should be capable of withstanding water penetration.
- The deformability of mortar should be minimal.
- Mortar should be inexpensive.
- In the site conditions, mortar should be easily workable.
- The mortar’s mobility should be adequate. It aids in the thin and even application of the mortar.
- It should be long-lasting.
- Good mortar should set quickly to optimise building pace.
Some Points to Consider in Cement Mortar Preparation and Usage
- Water shouldn’t be added until the colour of the sand-cement mixture is consistent.
- The sand-cement mixture should be used within an hour if water is added, as cement initially sets in 30 minutes or less.
- Only a steel or wooden platform should be used to mix the mortar or the concrete. Otherwise, water will wash the cement away.
There are many mortar types and the right one for your purpose depends upon your requirements. The best ones meet necessary industry standards that make them extra effective and hence improve the strength of your structure.
