Ordinary clay brick: a general term for clay refractories with regular shapes. The main chemical components are alumina and silica, and also contain ferric oxide, calcium oxide, potassium oxide, sodium oxide, titanium dioxide, etc. that act as fluxes. It is divided into ordinary clay bricks, multi-clinker clay bricks, all raw clay bricks, high siliceous clay bricks, etc. It has the characteristics of good high temperature performance and good thermal shock resistance. It uses hard clay clinker (all raw clay bricks as raw material) as raw material, adds an appropriate amount of plastic clay, and is plastically molded or semi-dry molded, and then sintered. made. It should be noted that the content of iron, calcium, potassium, sodium, titanium and other metal oxide impurities in the raw materials should be strictly controlled during the batching, otherwise they will start to form a liquid phase below 1000 °C, which will affect the high temperature performance of the product. Clay bricks are often used as refractory materials for blast furnaces, hot blast stoves, glass kilns, ceramic kilns, rotary kilns, lime kilns, etc.

Excellent clay brick: Clay fire brick with refractoriness not lower than 1699℃. There are three kinds of ordinary, crack-resistant and slag-resistant.

Clay bricks are widely used in early construction in my country, and are still the main material for wall masonry today. The standard clay bricks are: 240×115×53

Standard brick:

Standard bricks are commonly used bricks in construction projects. They are widely used in brick load-bearing walls and also in non-load-bearing infill walls. The dimensions of the clay bricks are: 240mm×115mm×53mm. Each brick weighs about 2.5Kg when dry, and about 3Kg after absorbing water.

Hollow bricks and porous bricks:

The size of the hollow brick is 190 mm × 190 mm × 90 mm, and each cubic meter weighs about 1100 Kg. The specifications of the perforated bricks are 240 mm × 115 mm × 90 mm, and each cubic meter weighs about 1400 Kg.
