All about wrapped shell

Rakushnyak is a stone that consists of a variety of small marine shells of mollusks. The most common option is the Crimean variety. This breed is not produced – it is in finished form mining from seaside lands. Today we will talk about the peculiarities of this stone and how to properly hold the laying of such material with your own hands.


Rakushnyak is often also called the shell. This breed has a texture that is similar to the texture of gravel. Depending on its basic characteristics, the stone is divided into several separate types: Congary, gastroene and brachyopodic.

The seven has excellent decorative properties, so it is becoming increasingly popular in finishing repair work. In addition, it has an interesting and beautiful color. The surface of the stone is permeated with a variety of minor pores, which allows for a long time to hold heat.

When properly treated, the stone becomes material with maximum resistance to various adverse atmospheric effects, so it can be used when finishing structures that will be located further outdoer.

Rakushnyak are increasingly used to finish residential buildings, because it will cost much cheaper of the usual building blocks. In some cases, it is additionally lined with a brick from the outside – this is done to protect the material from the unnecessary amount of moisture.

Materials and tools

To complete the wrath of the crown, you should prepare everything you need in advance for this. In addition to the stone itself, you need to purchase components for solutions. For this you can use the usual cement. And also need to prepare a bulk container in which the solution will prepare.

As the necessary tools for masonry, you need to take a construction level, trunk, roulette, hammer and shovel for the kneading solution. When calculating the required amount of stone, it is necessary to take into account the area you want to set out (no window and doorways are not taken into account).

Consumption and solution composition

Before starting construction work, you must correctly knead the solution, observing all the proportions. As a main building, you can use or a conventional cement, or a special mixture of grades 10, 25 or 50.

When making a mass in it, you should add a small amount of lime. Mandatory element is water. When mixing all components components, a construction solution of a viscous consistency should be. The composition is sometimes done using tyrs. And also other elements may include:

  • clay;
  • Moore;
  • sand;

If you use when cooking sand, then 1 bucket cement will leave for 4 buckets of such a material. In the manufacture of the composition, first mixed together with each other, and only then water is gradually adding to the resulting mass, and it’s thoroughly stirred.

How to put?

When the solution and the sewer itself will be ready, you can proceed directly to the installation of the material. First you can outline the scheme of future masonry, which will help when installing.

The masonry of the walls can be made in several ways: one-row, double-row and multi-row method with sutures. In the last two cases, the installation occurs in such a way that there are alternate blocks laid across each other (spoonful rows) and along (tonge rows) of wall coating.

With a double row method, such blocks will be alternating constantly. With a multiple method, several spoonful lines are first forming (most often 3-5), and then one tile row is mounted. Single-row installation method is used when the masonry occurs in ½ brick. In all cases, work starts with the formation of the corner of the structure.

In any case, you need to track so that the vertical filling of the seams was sufficient. In some cases, the finished building composition in them has to pour from above.

Remember that the thickness of vertical suture areas in the process should not be more than 20 millimeters. The thickness of horizontal seams should not exceed 15 millimeters.

In the process of laying shellucas, seams should be paid to. If they are incorrectly fill, then in the coating there are small empty “bridges”, which will pass through themselves cold, which will significantly weaken the thermal insulation of the whole building.

The thickness of the bearing wall coatings, as a rule, corresponds to the thickness of the stone blocks. If you build internal partitions that are not supporting structures, then the laying is better to produce half the block.

When finishing, such material can be attached to another building. This will make the overall design even more durable and reliable. Such a laying under the extection will look most presentable and neat.

If you are laying a whole stone, then on one square meter will leave approximately 25 blocks. If you make a finish in half the stone, about 13 blocks will be needed to the same area.

When you put the last top layer of the shell, it will need to pour a concrete tie. Do it for aligning the surface. Then you need to put a special reinforcing belt on top of all. To do this, it is better to use fittings, the reinforcing grid will also be able to approach.
