lime cement mortar ratio

Whether you’re working on a professional jobsite or at home on a DIY project, few bonding agents are as versatile and as essential as mortar. But despite its versatility and wide-spread use, all mortar is not the same. It’s also not the same as concrete or grout, for example

As it turns out, there are many different ways to combine mortar’s essential ingredients. In other words, there are different mortar mix ratios. Each of these variations comes with different properties, making them ideal for use in different types of projects. Some variations are better for use above grade or below grade, while others are limited in their ability to bear weight

While these ingredients are fairly straight forward, they can be combined in differing volumes to create mortars with differing properties. These different combinations rely on “mortar mix ratios” to ensure that they can be reliably recreated on demand without wasting raw materials or time

Like a recipe, a mortar mix ratio will be expressed in terms of “parts,” as in “ 1 part cement, 1 part lime, and 6 parts sand.” In theory, these basic ingredients could then be combined using proper techniques to create mortar with a desirable consistency and productive properties after setting


There are a wide variety of mortar mix ratios, especially when it comes to special-use applications of mortar. However, there are four main types that see the most use in professional and DIY circles: N, O, S, and M

You may also see mention of “type K” mortar while researching the right mortar mix ratio for your upcoming project. While this type still sees use, it is limited to restoring historic structures due to its extremely low compressive strength. Should you need to make type K mortar, it can be made by combing 1 part cement, 3 parts lime, and between 10 to 12 parts sand

Type N is the most common mortar mix ratio used on professional and amateur jobsites today. That’s because its basic recipe efficiently uses mortar’s essential ingredients while still providing a solid, reliable bond in many environments


Because of this mixture’s strength against heat and other weather, it often sees use above grade in both exterior and interior projects. In particular, type N mortar sees a lot of use in soft stone masonry projects due to the aforementioned properties

As with any commonly used construction materials, some slight variations of type N mortar exists. However, the most common mortar mix ratio for type N is 1 part cement, 1 part lime, and 5 to 6 parts sand

This is because type O mortar, after drying, is noticeably weaker than the basic type N. In fact, it is not recommended for load-bearing use due to its meager 350 psi compression strength. Instead, it is best suited for indoor projects that are above grade


Next up is type S mortar, which sees a lot of professional use in civic projects such as sewers and manhole shafts. That’s because type S, after setting, has a high tensile bond strength and high compressive strength of over 1,800 psi that allow it to withstand the pressure of below-grade applications

Making your own type S mortar is fairly straight forward. Simply combine the following ingredients: 2 parts cement, 1 part lime, and 8 to 9 parts sand. This mortar mix ratio is very similar to type O mortar, so be sure to carefully measure your ingredients when making either type

This allows it to be used in a variety of below-grade applications, including driveways, retaining walls, and in-ground foundations. However, type M is also known for its poor adhesion and sealing properties. As such, it should never be used in an application that exposes it to the elements


If that wall will bear a modest amount of pressure, standard type N mortar should suffice while still efficiently utilizing your raw ingredients. However, if that wall will end up bearing an extra-large load, you may opt for type S mortar

Meanwhile, if you’re interested in sealing tiles or stones together for a masonry project, then you’ll need to choose a mortar with reliable bonding properties. Your choice on this front should depend on what materials you are actually using, though

All in all, you have some options before you if you’ve decided that you’ll be using mortar for your upcoming project. While it may take some testing and some further research, you should absolutely take the time necessary to figure out which mortar mix ratio will best suit your project’s needs


As such, it is essential for you to determine if type N, O, S, or M will suit your project before buying raw mortar ingredients. Don’t hesitate to reach out to a trained mason, either. They can provide you with productive insights into how each type will perform in your specific environment as well as any tools you might need for the job

Cement mortar ratio for plastering | plastering & it’s types, hi guys in this article we know about cement mortar ratio for plastering & what is plastering and its types. And also cement mortar ratio for external brick wall plastering, internal wall plastering, concrete wall plastering, ceiling plastering & roof plastering

Plastering is done on the brick and concrete walls to remove surface imperfections, increase smoothness,maintain line level and alignment. In addition to that it also acts as a protective surface for external and internal wall made of brick or concrete. Different types of plaster like Cement plaster, Gypsum plaster and Lime plaster are the commonly used as plastering materials for house constructions

Cement plaster is made by mixing cement and sand in aquired definite proportions for different types of plastering. Cement plaster is applied to both interior and exterior walls to give them a smooth surface

Plastering is thin layer of cement mortar adhesive material put over the brick wall for protection from environment ,smooth surface, good finishing, good looking & increasing the strength of brick wall

We know that external part of brick wall is more prone to sever climatic condition, its needs more protection from outer side, plastering make it strong and damp proof and prevent from seepage of water in brick wall

Plastering is the term used to describe the cement mortar material spread over the both face plane and rough surface of irregular and coarse textured brick wall,beam, roof,column, concrete wall and ceiling to make it stronge, more durable,provide a smooth, hard and leveled finish surface which can be painted for good appearance

In actual Plastering process is an art, truly recognized for constructing the base. It refers to the construction done with cement plaster which includes a layer of plaster on an interior wall or plaster decorative moldings done on ceilings or walls. The process of creating plasterwork is known as Plastering

Plastering is a unique skill to plaster the brickwall, leveling it and achieve a good and even finishing. Plasterboard is to form the sub-base for ceilings, partition walls. An adequate and rigid frame made up of timber battens is needed for it
