calcium silicate bricks uses Calcium silicate is known as one of the best fireproof insulators. If calcium silicate is used as a fireproof insulation, it is usually sprayed on the surface (European method) or it is applied as thin coatings on the surface (American method). Since calcium silicate is sensitive to water and moisture and reacts with water, it is mandatory to use anti-moisture and waterproof coatings and coatings on it. Also, calcium silicate is one of the ingredients of iron slag in smelting furnaces and blast furnaces, and it is used to increase the pH of acids. Calcium silicate sheets are the new generation asbestos-free sheets that are completely compatible with the environment and do not harm human health. These sheets are used in the interior and exterior facades of the building, and the type resistant to moisture and heat insulation is also produced.
Calcium silicate plates are cement plates from the fiber cement family, which have achieved a very high hardness compared to their similar types by incorporating calcium during production. By combining two calcium silicate plates with a thickness of 6 mm each and a polystyrene foam in the middle, it can be used as a very ideal wall in the construction industry. The walls made by calcium silicate are known as ultra-light walls, they are very effective in the weight of the structure and reducing the weight of the structure, especially in metal structures. Calcium silicate wall is the most ideal wall in the construction industry. The wall is made of a polystyrene foam and two sheets of calcium silicate, which are placed on both sides of the foam. The panels can be produced with a thickness of 5 to 20 cm. The width of the panels is 1.20 and its height is a maximum of 3.5 meters. Styrene is very low (depending on the thickness of the coating and insulation density it is about 17-25 kg/m2), while the weight of a 22 cm thick brick wall is about 400 kg/m2. Calcium silicate insulation has a very high resistance to water and heat; for this reason, it is used more than gypsum insulation. Calcium silicate insulation is known as one of the environmentally friendly insulations, which has relatively good performance against moisture.
Due to the structure and production method of calcium silicate insulation, this insulation also has a good performance as a sound insulation. Many insulators lose their performance over time because their R-Value decreases. But this issue is not true in relation to calcium silicate insulation, and this issue makes it have a longer life. These two insulators both have a good performance in terms of being resistant to heat, but other desirable characteristics of calcium silicate insulation have attracted a lot of attention. Especially in industries where the temperature is very high. Paying attention to the increasing expansion of all types of building materials and new materials in the construction industry today, maybe at first glance, talking about the role of bricks in construction is not very important and it smells old, but the reality is something else! Although brick buildings have often been replaced by other construction materials over the past years, brick in many, varied and different forms is still one of the most widely used materials in construction, and its role is no less important than that of beams and rebars. Although the price of rebar and rebar has fluctuated a lot over time, brick has not experienced much fluctuation. calcium silicate bricks are made with Advantages and disadvantages of vermiculite insulation The disadvantages of vermiculite insulation are as follows: Some vermiculite mines in the world contain asbestos, which is harmful to health.
Of course, from 1990 onwards, the production of vermiculite products containing asbestos mineral was stopped or their vermiculite was purified. Limitation of resources in the world
- 1. Scope of application in terms of temperature Due to the inorganic nature of the calcium silicate thermal insulation, its resistance and nature will not simply change at high temperature.
- Volume changes due to rising temperature. Permanent temperature changes in insulations can cause linear changes in dimensions. In calcium silicate insulations, the maximum linear changes at a temperature of 900 degrees Celsius is 2%, which is a very small amount.

- Thermal conductivity This issue is considered the most important factor in choosing an insulator. Calcium silicate insulation is considered a good choice not only because of its low volumetric weight and ease of transportation, but also because of its low thermal conductivity.
- Limitation of consumption Usually, these insulators are available in the form of boards, half pipes, knees, and even special geometric shapes, so it is possible to cover the surfaces with factory-made parts.
At the same time, the property of cutting allows us to create any shape in time. If the shape is very special or the target area is complex, you can make a paste of calcium silicate powder with an adhesive and use it as a mortar. Companies producing this material are able to supply calcium silicate in liquid form.
In other words, it can be said that there are no restrictions for the use of calcium silicate insulation.
- Other benefits Relatively good compressive strength and high stability Non-flammability Resistance to corrosion and chemical compounds and fungal and biological pollution Very good strength to weight ratio No corrosion of steel and iron pipes Low energy consumption during production It has annuity among other insulators. These sheets are the new generation of asbestos-free sheets, which are completely compatible with the environment and do not harm human health.
Disadvantages of calcium silicate Sensitive to moisture and water and steam penetration Mandatory use of anti-moisture and waterproof coatings due to sensitivity to moisture This insulation is sometimes known as dull insulation, which is actually a combination of its two parts. In general, calcium silicate insulation is used to insulate pipes and equipment that must withstand high temperatures. This insulation has good performance against fire and is generally offered in three forms: tube, board and block. Irik company supplies calcium silicate insulation in two forms, board and tube. Calcium silicate insulation is made in such a way that it has high strength against high pressure and temperature. This type of insulation can withstand temperatures of 650 to 927 degrees Celsius. Calcium silicate insulation is known as one of the warm insulations and thermal insulations because the heat transfer coefficient in this insulation is very low.
