Flexural strength MPa	More than 4.5 (Suitable for pedestrian trails)	More than5.0(Suitable for light lane)	More than5.5(Suitable for heavy-duty lane)
Size mm	200100; 230115; 240*120
Compressive strength	More than50
Wear resistance	Grinding pit length not greater than 55mm
Frost resistance	25 freeze-thaw cycles , the dry mass loss does not exceed 2%

Fired brick edge:

A:Strength and life:

Compression value of minimum national standards of flooring materials ≥ 23Mpa cement brick is about 30 Mpa , we fired brick ≥ 50 Mpa for this reason that much longer than the cement brick life of about 3 to 5 times .

B:safe and environmentally friendly

The fired brick mainly shale , fired at high temperature surface glazing , do not fade , non-radioactive . Has good permeability , water retention , and regulation of air humidity , effectively alleviate the urban heat island effect .

C:Economic and Culture

Although the one-time investment is large compared to the cement block , but the beauty of the building with the passage of time will not disappear late , there is no need frequent maintenance . Even if the ultraviolet radiation , acid rain , brick colors never fade , but more purely aesthetic still . The initial investment diluted to a long period of time reflects the value of each investment .

General Information:

Fireclay bricks are made from clinker clay by mixing, forming, drying, sintering and machining. The Al2O3 content ranges from 36% to 42%.
Fireclay bricks feature stable mechanical strength and good thermal shock resistance, withstanding high temperature up to 1750.
They are commonly applied as refractory lining directly exposed to heat or backup insulation layer in all kinds of industrial kiln or laboratory furnace.
