The proportions of ingredients for bricklaying or stone laying mortar is decided based on kind of binding material used. Following are the types of mortars based on different factors: This type of mortar used to bind bricks and stones in masonry construction. The mortar mixture can be mixed on-site, using a shovel or hoe, or a mixing tub or with a cement mixer.

This is a very heavy mortar which has a bulk density of around 22KN/m3. Let’s understand them: Just like the name suggests, in this type of mortar cement is used as the binding material and sand is used as an adulterant. Hence there is a need to add air entraining agents to the cement mortar to make it more plastic and workable, this resulted in the invention of aerated cement mortar.

As we already mentioned cement has high strength than lime and lime mortar have high plasticity so when these two materials are mixed the result that you get is a mix of two properties in a very economical way. This type of mortar is suitable for those structures which are more prone to chemical attacks. load bearing wall, footing, retaining wall are examples of below grade applications.

Just as the name suggests, this kind of mortar helps in reducing noise levels by acting as a soundproofing layer. But again, the use of a good quality material in decent proportions actually lead to good strength mortar.

Sadly, our construction industry is plagued with challenges; and considering the pool of challenges, the most frightening one is the shortage of natural resources like sand and water which is constantly rising issues like time overrun and cost overrun.

Occasionally half amount of surkhi and half amount of sand is also used. When working with brick and other masonry units, it is very important that one uses the right type of mortar for the masonry. It is used to reduce the noise level and acts as sound proof layer. This aggregate is used in the mortar mix to cut the required proportion of the cementitious materials and also to resist the shrinkage of the cement. The system also totally eliminates the requirement for curing, consequently leading to water savings. Consequently, the mortar will have high plasticity of the lime and high strength of the cement.

Mud mortar is useful where lime or cement is not available.

Mortar consists of inert siliceous (sandy) material mixed with cement and water in such proportions that the resulting substance will be sufficiently plastic to enable ready application with the mason’s trowel and to flow slightly but not collapse under the weight of the masonry units. Well, cement, concrete, and mortar all three are different construction materials. Hence, when it comes to preparing a good strength mortar, sufficient cement content and well graded fine aggregate needs to be used.

There are two types of limes namely fat lime and hydraulic lime.

When water is added to this sand-cement mixture, the cement gets activated so that it cures or hardens. The ratio of cement to lime ranges from 1:6 to 1:9, and it is cost effective. Mortar is generally sold in bags, in a dry pre-mixed form which can be later combined with water. Hydraulic lime and sand in 1:2 ratios give great results in damp conditions and quite suitable for areas that are waterlogged.

Basically, it is cement mortar to which air entraining agent is added to increase plasticity and workability.

In surkhi mortar, lime is used as binder material and surkhi is employed as fine aggregate. For construction purpose, different forms of mortar are used, but again depending on its applications, mortar can be classified into many different types.
The proportion of cement to sand may varies from 1:2 to 1:6. Cement mortar gives high resistivity and strength against water.

Ready to use, mason friendly and easy to transport, Next construction activity can begin within 24 hours. Bricklaying or Stone Laying Mortar. What are the properties of good building stones? Major Problems in Concrete Pumping Works: How to Avoid Them? Added to that, it used for repointing where the structural integrity of the wall is intact.

This kind of mortar is commonly used in the packing of oil wells.
Become VIP Member. Fire Resistant Mortar. Gypsum mortar consists of plaster and soft sand as binding material and fine aggregate.

Let’s break down the benefits of this amazing product: The bottom line, Dryfix addresses all the issues of policy changes, time overrun, cost overrun, waste generation, negative impacts to the environment and excessive resource consumption quite well. Omissions?

What is the difference between Tender and Contract Documents? To prepare this special mortar, fine aggregates from heavy rock and suitable admixtures are used.

It is a medium-strength mortar minimum 12.4 MPa (1800 psi) with high bonding ability.
