Bricks play a very important role in civil construction and have different types, Anti-acid brick is resistant to acidic substances and all kinds of acids, that's why it is used in spaces that are close to acid.
Acid Resistant Refractory Bricks
Anti-acid bricks are a special form of masonry bricks that are chemically resistant and thermally durable.
These bricks are used for masonry and flooring that are susceptible to chemical attack, such as towers in chemical factories.
Acid resistant refractory bricksare used in industrial places such as factories and workshops, including chemical plants, dairies, plating tanks, etc., due to their acid resistance.
Acid-resistant firebrick is structurally different from other bricks.
The raw materials for making this brick include minerals and refractory mineral pumice.
The molecular structure of this type of brick is regular and resistant and does not disintegrate at high temperatures.
It also maintains its physical and chemical properties at high temperatures and its heat tolerance is high.
Acid Resistant Bricks Specification
There are different types of anti-acid bricks.
The most used is red shale.
| Title | Description |
| Properties | High Compressive Strength |
| Usage | Construct Kilns and Furnaces |
| Components | Alumina and Silica Clay |
| Withstand | Greater Than 2000°C |
Others include clay, silica brick and carbon brick.
Anti-acid brick, like decorative brick and ten-hole brick, is one of the types of bricks.
This type of brick is a material resistant to corrosive substances and acid, which uses quartz, feldspar and clay as the main raw materials and fires at high temperature.
This brick has many properties such as high acid resistance, high density, low water absorption, good corrosion resistance and easy oxidation at room temperature, and it is not easily contaminated.
Acid-resistant brick can resist most acids such as hot chlorine salt, hydrochloric acid, sulfuric acid, nitric acid except hydrofluoric acid and hot phosphoric acid.
Acid Resistant Refractory Bricks features
It can also resist alkali with different density at room temperature Acid-resistantnt firebrick is the latest type of brick that is used in today's buildings because of its high advantages.
This brick is a thermal insulator that, in addition to preventing energy loss, is also highly resistant to heat.
Firebrick does not lose its physical and chemical properties at high temperatures, that's why it is used to cover the inner wall of the fireplace.
Long life, durability and strength, beauty and color stability are the special features of this brick, which makes it the best option for architects and builders.
This type of brick is resistant to erosion, scratches, heat, sunlight, moisture and weather changes.
Due to the use of mineral materials in its construction, it is considered a unique brick for construction purposes.
The price of this brick is higher than other bricks.
These bricks are used for the facade of the building and are very resistant to heat, temperature changes and fire and have extremely high strength.
These bricks have a variety of colors based on the type of soil they are used in.
The most common colors are Semirmi red, chamotte, gray, rustic, white and black brown.
Clay is mainly used to make firebricks.
This clay can withstand high temperatures without significant changes in structural properties such as melting or softening.

Acid Resistant Refractory Bricks advantages
There are mainly three types of refractory bricks: 1- Acid refractories, which include ordinary fire bricks, silica bricks and Ganster bricks.
2- Basic refractories that include magnesite brick, dolomite brick and bauxite brick.
3-Neutral refractories, which include chromite brick, carborundum, chrome magnesite brick, column brick and forestrite brick.
In the type of acid refractories, ordinary firebricks are made of natural clay with a mixture of crushed clay and sand.
It contain 50-75% silica and 20-40% alumina, and are used as a good quality acid refractory lining for furnaces.
Which can withstand up to 1600 degrees Celsius.
In the types of refractory bricks, silica brick contains 95% silica and is made of sandstone or quartzite with the addition of 2 to 3% lime as a binder and flux.
It is used for the acid coating of furnaces to produce glass and walls and arcs of steel furnaces.
It is suitable for open base and copper smelting furnaces and has a resistance of up to 2000 degrees Celsius.
Ganster bricks are also made from different types of ganster stone.
This stone contains 85% silica and 10% clay with the addition of 2% lime.
It is also very hard and compact and can withstand temperatures above 2100 degrees Celsius.
Engineering Bricks
Engineered bricks are specially formulated to exhibit high compressive strength and low porosity.
They are often used in structures where the overall strength of the material as well as its resistance to water and freezing are important features.
Due to its unique properties, engineering brick is used in construction projects that require resistance and in cases where the appearance of the work is not considered.
For example in tunnel projects or for underground applications that require anti-moisture materials such as sewage from These types of bricks are used.
Clay and lime are the raw materials for all bricks, but in the manufacturing of clay, lime was mixed with straw and the clay was formed from straw mortar in wooden molds and by hand.
Bricks are marketed in different dimensions, as mentioned, engineering bricks are one of the most popular types of bricks.
But what are the characteristics of a quality engineering brick?
High-quality engineering brick has a high compressibility, which means that its raw materials are produced from fine grains of clay and lime with high pressure devices.
It causes the brick to compress and its constituent components appear It becomes smooth and mirror-like.
Holes are created on the surface of high-quality engineering bricks, which cause the penetration of water and cement.
It is the mortar drawn during construction between the arranged rows of bricks, which Holes are created on the surface of high-quality engineering bricks.
It causes the penetration of water and cement, that is, the mortar drawn during construction between the arranged rows of bricks, which helps the strength of the building.
A structure is used that can bear a high weight, such as the foundation and the bearing points of the building, on which the entire weight of the building rests.
The Answer to Two Questions About Refractory Bricks
1: Where are refractory bricks typically used?
Kilns, furnaces, and other high-temperature structures are commonly built with refractory brick.
2: When heated at high temperatures, do refractory bricks release harmful chemicals?
Due to chromium in stainless steel, leftover refractory brick/mold and ashes may be harmful.
