One of the questions that the concepts of brick calcium silicate bricks size a drop of water may not seem very significant, but billions and billions of such drops make up the area. Similarly, each brick plays an important role in forming a strong foundation when building your home. I can never beat the ruggedness and durability of brick pavers to create a dramatic path to the front door or a meandering path through the garden. Brick is needed, but people hardly know about its types and uses. Brick is the oldest building material. Brick began its history in ancient Egypt and Rome. At this time, bricks were used to build complex structures that included arches and other items. There are different types of bricks that are available in the market and they are named according to their use, size, quality, origin, texture, consumables and how they are formed. Bricks are not only used in residential and building constructions, but also one of the essential elements of production units in industries. In industries, bricks are used in furnaces. It is also used in the lining of furnaces. It is said that the first bricks used are dry bricks. Dry bricks were made by giving a special shape to clay or mud. In the past, thermal cooking was not familiar to humans. 
In this way, the bricks were baked and dried in the sun until they were strong enough. Today, perhaps a brick is at the peak of its development. Its properties are almost perfect, it is stronger, resistant to water and freezing. Brick is a very reliable material that cannot be compared to any other material in maintaining heat and durability.Also, brick is an ecologically pure material that is sustainable according to sustainable standards. According to the materials in it, it is also called sandy lime or limestone. These types of bricks are made of lime, which are bonded with silicate materials instead of being baked with clay. The raw materials needed to make these types of bricks include lime, sand, quartz, flint or siliceous stones, which are used in crushed form, and all of them are mixed with minerals to give color. It takes about thirteen to fourteen hours for the bricks to harden. The final result is uniform and accurate. It requires careful attention to avoid damaging the brick and brick layer One of the types of bricks is glazed brick. A brick whose surface is covered with colorful and attractive glazes is called a glazed brick. In order to get to know more about this lovely and popular brick, it is necessary to pay attention to the glaze. Glaze is a mixture of stone and silica, which is combined with clay to preserve the surfaces of its glasses, and finally produces a metal. This protective coating increases the resistance of bricks against factors such as water penetration and erosion. For this reason, glazed bricks are very durable and their original appearance is always preserved. The difference between glazed brick and other bricks is only in appearance, and this glazed surface has given this type of bricks a very attractive appearance. 
when were calcium silicate bricks used
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 its resistant type is resistant to moisture and heat insulation. Calcium silicate plates are cement plates from the family of fiber cements, which have been obtained by combining calcium while compared to their similar types, with very high hardness. 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. Calcium silicate insulation weighing about 400 kg/m3 was made by forming calcium silicate bonds. In this method, raw materials that can be used internally and processed inside the Auto Clave device and at a pressure of 12 atmospheres in the presence of saturated steam. Pulp was used as fibers to strengthen the insulation. 
The obtained product has a very low heat transfer coefficient and temperature tolerance of about 900 degrees Celsius. According to some craftsmen, calcil insulation has the best performance against fire. These insulators are sold in three forms: tube, board and block. Calcium silicate insulators are made in such a way that they maintain their strength against mechanical pressure and high temperature. This insulation is a chemical compound consisting of lime and silica, which has adhesive properties like cement. The chemical structure of calcil is formed by different proportions of calcium and silica, which form hydrated silicate along with reinforcing fibers. The heat transfer coefficient in this insulation is very low. Also, it does not produce harmful gas or smoke when burning on top. Therefore, it is known as a green building material. Calcium silicate is available in industrial and laboratory grade in brick-and-mortar or online markets. Purchase offers for this insulation can be made by searching the substance name or registry number (CAS code) in the list of valid providers in the Internet viewer. This material is sold in the market with European and American terms. The European type is Calcil as a spray. Its American version is also sold as thin and continuous coatings. This product is sold in various types of boards, pipes and half pipes in various thicknesses. It has been observed in cases that purchased calcium silicate is sensitive to water and reacts with water. In these cases, waterproof and waterproof coverings are used on it. 
As you read in the article, brick has been used as one of the building materials since long ago and it is considered the oldest material made by human hands. You also noticed that the use of bricks as a building material in Iran has an ancient history of thousands of years. Besides this, the blocks that studied the sizes of the regular and cubical shapes are in some cases made of clay and are used in different parts in the case of various types and designs and different remnants. Therefore, according to one of the mentioned characteristics, brick is considered one of the most popular building materials and at the same time widely used. In the end, we hope that the following article has helped to increase your information and knowledge.
