Description
Technical field
The invention belongs to road technical field of board processing, in particular it relates to a kind of environmental protection using riverbed sludge as major ingredient
Type pavior brick and preparation method.
Background technology
It is non-burning brick, also known as no-firing brick, due to that can avoid conventional sintering brick serious waste land resource and prepare
During discharge SO2The problem of polluting environment, has been obtained for being widely applied in building field.Pavior brick is a kind of floor file
Material, existing pavior brick is with cement and gathered materials for main raw material(s) that mostly blended, roasting or other moulding process are made
It is shaped as the concrete road pavement brick of the shapes such as triangle, square, regular hexagon.
At present, with Chinese Industrialization, the quickening of urbanization process, water pollution problems is increasingly severe, and environmental dredging is
Effective engineering means of river lake endogenous pollution are removed, at reparation, pollution administration rivers and lakes, are inevitably produced a large amount of
Dredged bed mud.Traditional sediment method is to deposit nature desiccation using stockyard, but this mode will not only take largely
Soil, and secondary pollution easily also is produced to surrounding enviroment in stacking process.Existing way does not meet people to ring yet
The full appreciation of border pollution, and the theory such as resource rational and efficient use, the environment-friendly, economic circulation advocated, belong to anxious and treat
The a great problem of solution.
In consideration of it, there is research that Dredged bed mud is used as into non-burning brick raw material, substantial amounts of Dredged bed mud, the method are consumed with this
