Acid resistant bricks price in comparison with other refractory bricks is higher and in fact the price of these products depends on the materials used in their construction.
Acid Resistant Bricks introduction
Acid-resistant bricks are used due to their high chemical resistance in industrial places exposed to corrosive acids in different concentrations.
Also, acid-resistant bricks are very efficient in sulfur pots and other similar equipment that, in addition to high chemical resistance, also require resistance to cracking due to extreme temperature changes.

Acid-resistant brick weighs about 3.5 kg, but this figure can vary depending on its type and size.
Therefore, the most common products are straight and wedge, which can be the end or edge.
The block can be radial and, in turn, is divided into longitudinal and transverse bricks.
Often in construction, dimensions of 230x113x65 mm are used.
Acid-resistant bricks may have some deviations from the dimensions specified by GOST.
The permissible error varies between 2-8 mm.
Sometimes it is necessary to work with a weak product.
It involves the use of a single or double limestone, each of which can be solid, hollow or porous according to the usual principle.
Hollow bodies have one or more cavities, their shape and dimensions are different.
Such blocks do not impose such an imposed load on the foundation of the building, and the walls, based on the described products, are characterized by thermal insulation quality.
Acid Resistant Bricks advantages
In addition, they are harsh due to the use of less raw materials.
But it is not recommended to use hollow materials if the structure is in direct contact with water.
When buying high-quality products, pay attention to the fact that they must be produced in accordance with GOST 474-90.
Acid-resistant brick in this case has small fractions in the fracture and its surface is uniform.
Do not use blocks that have internal cracks.
This shows that marriage is not a long service brick.
It is necessary to ensure that there is a marking, it is located on one side of the brick.
In the box, the package as well as the pallet must contain a label that may find information about a class of the product, the number of goods, the number of a party and the date of production.
During transportation, the bricks must be packed in pallets manufactured according to the specifications 21-28-60, they can be replaced with containers made according to the standard 19667.
To prevent rotation during transportation, the brick is tied with a metal strip.
It is very important to pay attention to GOST when buying.
Acid-resistant brick without complying with the mentioned norms will not meet the mentioned quality characteristics, it will not protect structures and structures.
Do not transport products in boxes or packages weighing more than 1 ton.
It is impossible to buy such a brick for private construction, because its cost is much more impressive than usual.
The main component of the raw material of acid-resistant bricks is silicon dioxide (SiO2).
According to acid refractories in the classification of refractories, refractory products contain a significant amount of SiO2 acid refractories.
Under high temperature roasting, it forms a large amount of mullite, which is a material with high acid resistance.
Due to the compact structure and low water absorption of Zhongguan acid-resistant bricks, it can withstand any concentration of alkaline media at room temperature.
But it is not resistant to high temperature molten alkali.
Acid-resistant bricks contain more than 70% silicon dioxide and are made by sintering.
Acid-resistant bricks are made of clay or other non-metallic materials that are processed by molding, coloring and other processes.
Acid Resistant Bricks conclusion
They are suitable for acid-resistant coatings and floor tiles or sheet-shaped acid-resistant products.
They are divided into glazed bricks and unglazed bricks.
The main component of acid-resistant bricks is silica, which forms a large amount of mullite under high temperature firing.
One of the most important characteristics of acid earthquake refractory brick is the following:
- High temperature resistance
- High strength, high pressure resistance
- Excellent thermal shock resistance
- High bulk density, good thermal conductivity
- Resistance to wear and acid
- Resistance to alkaline corrosion
