What solution is needed for laying the furnace

In order to erect a heating structure, you need to know what solution is needed for laying the furnace. Indeed, much can depend on it: the term of operation, the quality of construction, and much more. Therefore, it is so important to carefully select the composition, proportions and take into account some of the nuances. This will be discussed in this article, we will understand which of the solutions is better.

Clay masonry mortar

To ensure heat resistance and linear expansion, it is advisable to choose the right materials for the manufacture.

IMPORTANT! It is worth remembering that the described mixture has not only the property of low bond strength, but also a decrease in the completeness of the layer. Therefore, there is the possibility of a conversion from high thrust to low.

How to prepare clay

The preparation process is necessary in order for the product to acquire its characteristic properties. This seems like a phased algorithm:

• Cleansing. The action takes place in a dry manner, that is, the substance is sieved through a sieve (cells of which are less than 2 * 2.5 millimeters). This eliminates various impurities and pollution. The only thing, difficulties can arise due to the fast clogging of particles. To do this, you can use liquid - moisten the soil.
• Cooking. First you need to take the tank. A substance is placed in it so that a layer with a thickness of about 150-120 mm is formed. Next, water is poured. It should completely cover the surface with an elevation of 1 centimeter. Then the clay mass is also placed on top. Similar manipulations are performed until the capacity is full. Then, as one day passes, you need to move the resulting mixture. Then add more liquid and let it brew for 24 hours. Readiness consists in the fact that after this time you again stir the product.

The proportions of clay and sand

In an aspect, there is a relationship between the ratio of these substances and the fat content that is inherent in the material. There are two varieties:

• Normal For its manufacture you will need 5 parts of clay.

REFERENCE! They should all be equal. Moreover, previously passed the cleaning process. In each of them, except the first, sand is added in the following proportions: 1/10, 1/4, 3/4 and the last one to one.

• Oily. Naturally, the proportionality in this situation will be different from the previous one. For starters, 5 servings are also being prepared and the first of them does not require transformations. But with others it happens like this: in the second and third pour 50% of sand and 100%, respectively. As for the fourth and fifth, it is 1 / 1,5 and 1/2.

Ordinary clay mortar

A factor affecting the composition of a substance is the intensity of heating. In different places of the design, it has various parameters. But in each case, the layer should not exceed three to four mm. If it is denser, but the strength of the structure becomes the least. So, there are two areas:

• Heat storage. It is characterized by heating to 600 degrees. The difference is the fact that this area does not interact with open fire.
• The fluff. The temperature indicator is less - 400 'of heat.

Chamotte clay mortar

The composition of the preparation includes substances such as fireclay soil and sand. The first of them makes up 30% of the whole part, the second - 70%. But it may be that the fat content is too high. It is then that you can change the proportions to 1: 1. It is worth neglecting the described solution when the chamber for the furnace is being manufactured, moreover, it should be all built of fireclay.

Clay for oven masonry

The substance of all his kind is different in that it is inherent in elasticity, strength, water resistance and ductility. It will be ideal if the clay is of medium fat content. In another outcome, for example, when it is oily, then evaporation of moisture from the surface will provoke damage. With subtle, the absence of all characteristic and necessary qualities. To find a really suitable product, you should use the search in the depths of the river banks, that is, where the layers have already been exposed.

How to choose clay for laying the furnace

To choose the best option, it is advisable to pre-test. There are several ways. These include:

• Drying. Within three days, it should absorb the water that you previously added to the mixture. If it does not crack, then the product is suitable.
• With the help of the fun. When stirred, it may happen that it will stick. This means high fat content.
• A ball formed from a mixture and a liquid is placed between two planks. Then it is determined: a lot of cracks - the substance is oily.
• The same indicator can be checked due to the absence of a gap when bending the flagellum from clay.
