                                           Simple Introduction of Clay Bricks
 
Clay brick uses clay as main raw material, after a process of mixing, extruding, air-dried and burning with the 900-1000 ° C, then formed.The main chemical composition of clay bricks are alumina and silica, also contains the role of the role of ferric oxide, calcium oxide, potassium oxide, sodium oxide, titanium dioxide and so on.
 
Clay brick is often used as blast furnace, hot stove, glass kiln, ceramic kiln, rotary kiln, lime kiln and other refractories. Clay bricks used widely in Chinese early construction until now, the standard clay brick specifications is 240mm × 115mm × 5mm.
 
Standard brick is the most commonly used brick in construction, it is widely used in brick-bearing walls, but also for non-load-bearing wall. The size of clay brick is: 240mm × 115mm × 53mm. Each brick is about 2.5Kg dry and about 3Kg after water absorption.
 
Strength of clay brick:Clay brick is characterized by high compressive strength, can withstand greater external force. The ability to reflect the bearing capacity of the brick is called strength; and the intensity of the intensity is called the intensity level. A brick of a strength grade for a building should be determined by the design unit.
 
Clay brick water absorption: clay brick has a certain degree of water absorption, can absorb a certain amount of water, how much water can be used to show that the water absorption. The water absorption is generally allowed in the range of 8% to 10%. Clay brick appearance quality:

Ordinary clay brick shape should be smooth, Founder. The appearance of no obvious bending, lack of shock, angle, cracks and other defects, when knocking out the crisp metal sound.
