Complete plant for autoclaved brick is made up of main equipment include blender,slaker,autoclaved brick machine,wheel mill,autoclave and some auxiliary equipment include box-type feeder,screw conveyer,climb fight,aggregate scale,belt conveyer,conserve dolly and ferry push.Many performances such as freezing resistance,stain resistance and compression strength of autoclaved brick are superior to artificial stone of solid clay bricks.The size of these bricks are same to the common solid clay brick,is 240mm x 115mm x 53mm,so we can use autoclaved brick to replace solid clay brick directly.It is a new-type materials for wall which is rapidly develop and apply in our country.
From GB50003－2001 we can see that contractibility rate and coefficient of linear expansion of autoclaved limesand brick are higher than those of firing stock brick setting(look at the blow table):
Coefficient of linear expansion and contractibility rate of brickwork
|Item||Coefficient of linear expansion/（×10－6/℃）||Contractibility rate/（mm/m）|
|Firing stock brick||5||0.1|
