Description
Technical field
The present invention relates to building material field, a kind of intensity is greatly for colliery wastes brick and the production method thereof of load larrying member body of wall specifically.
Background technology
The main component of colliery wastes brick is coal gangue.Coal gangue is the rock that common consedimental organic compound and mineral compound mix with coal in coalification course, usually in thin layer and in coal seam or top, coal seam, at the bottom of coal seam, being that mine that the quantity that produces in construction of coal mine and coal digging, dressing of coal by washing process is larger is solid-state dumps thing.Its main component is Al
2o
3, SiO
2, also contain the Fe that quantity does not wait in addition
2o
3, CaO, MgO, Na
