used refractory bricks for saleWhat is a brick facade? We know that there are different types of bricks, such as firebricks, decorative bricks, clay bricks, etc. The brick facade is one of the most important and original buildings, which is highly regarded due to its unique characteristics.
This brick is used in the exterior of the building and according to the quality and percentage of water absorption, it is divided into two groups one and two.
Brick facades are a type of ordinary brick that have less weight.
These types of bricks are resistant to heat, humidity and water penetration and can be prepared in different sizes and different colors with creative designs.
Among building materials, brick is special in two ways: fire resistance and specific size.
As a product of the fire furnace, it is more resistant to building fire than any other building materials.
Its size may account for much of the love many people instinctively feel for brick: a traditional brick is shaped to conform to the human hand.
Hand-sized bricks are less likely to crack during drying or firing than larger bricks and are easy to work with for building.
This small unit size makes brickwork more flexible in adapting to small geometries and patterns, and adds a pleasing scale and texture to a brick wall or floor.
The city of Sfarorin and Shall has a large number of brick kilns, which are famous throughout Iran.
Bricks made of clay have been used for at least 5,000 years.
Apparently, for the first time, it was used to build cities in the Mesopotamia and the Indus Valley in Pakistan.
At first, people mixed clay and straw by kicking them to make bricks.
Then the prepared mixture was poured into rectangular molds and dried in the sun.
A brick dried in the sun could not support itself without straw.
Eventually, the people of Babylon, Assyria and ancient Egypt discovered that by melting clay, bricks were obtained, which were stronger and more resistant to weather.
In ancient times, on the banks of the Tigris and Euphrates rivers and after their floods, a lot of mud was deposited on the surface of the earth.
These sediments, which had special adhesion, and after their water evaporated due to the sun's radiation, cracks appeared in the form of irregular cubes.
From these sediments, it was used as mortar for layered mud walls in those days.

Due to their large weight and volume, which makes it expensive to transport them over long distances, bricks are produced by a large number of relatively small and scattered factories from various local clays and shale.
Raw materials are dug from pits, and then these raw materials are crushed and ground and screened for fine consistency.
Then these materials are mixed with water to produce a paste ready to be shaped into bricks.
[2] Today, three main methods are used to shape bricks: soft mud process, dry pressing process and hard mud process.
The oldest is the soft mud process, in which a relatively moist clay (20-30% water) is pressed into simple rectangular molds by hand or with the help of molding machines.
In order to prevent the mud from sticking to the molds, the molds may be immersed in water immediately before filling and produce bricks with a relatively smooth and dense surface, which are known as water-struck bricks.
If sand is sprinkled on the wet mold just before forming the round brick, sand-struck bricks or sand-mold bricks are produced, which have a matte surface texture.
[2] As the clay is removed from the mold, textures or thin mixtures of colored clays may be applied to the surface as desired.
A rectangular column of wet clay is pressed by extrusion pressure onto a cutting table, where automatic cutting wires cut it into individual bricks.
Bricks produced by the hard mud process are very uniform in size and shape.
In cases where greater variation in appearance is desired among the units, the bricks can be rolled and tumbled prior to firing.
Tumbling softens edges and corners and creates more individuality in appearance between units.
bulk fire brick There is no truly standard brick.
The closest thing in the US is modular brick, which is designed to build walls in 4-inch (101 mm) modules horizontally and 8-inch (203 mm) vertically.
More broadly, the term modular can be applied to any brick that is sized so that when the thickness of the mortar joints is included, the wall dimensions correspond to appropriate whole units such as 4, 6, 8, 12, or 16 inches.
(102, 152, 203, 305 or 406 mm).
The size of non-modular bricks, especially in terms of width or length, does not necessarily correspond to the proper dimensions of the whole number in the built wall.
kiln refractory bricks The city of Tehran, with its old buildings and historical monuments, has both a traditional and a very modern identity; in the construction of buildings such as Shams-ul-Amara, Dar al-Funun, Palace of Museums, historical mosques, brick buildings in Hassan Abad area, Sardar Bagh National, Museum of Communication, Saderat Bank building, Sasanian/Achaemenid style brick buildings, Museum of Ancient Iran and Ministry of Foreign Affairs, Registration and Documents Building, schools Old, Chaharsouk Dome, Tehran Grand Bazaar, bazaars, caravanserais, and the building of many houses and shops in the old parts of Tehran are made of bricks.
2600 degree fire brick Paving bricks (ASTM C902) used for paving, driveways, and patios must not only be frost-resistant, but also resistant to water absorption and abrasion.
Fire bricks (ASTM C64) are used to cover fireplaces or furnaces.
These bricks are made of special refractory clays that can withstand very high temperatures.
Refractory bricks are laid with very thin layers of refractory mortar.
