Description
Technical field
The invention belongs to construction material preparing technical field, be specifically related to that a kind of slag building waste is non-burning brick and preparation
Method.
Background technology
Along with the acceleration of urbanization process, economic exhibition of not stopping paying out, large quantities of old buildings are removed, discarded brick, steel
The social topics being treated as increasingly meriting attention of the building wastes such as reinforced concrete fragment.If but simply filling, not only shadow
Ring urban environment, waste land resource, also can cause the waste of the huge energy and resource, utilize building waste to prepare Novel free
Bake bricks and can not only effectively process rubbish, also comply with the demand for development of current construction material.
Slag is the side-product in steelmaking process, is one of the primary solids garbage of steel industry.Due to by steel-making skill
The restriction of art, domestic slag storage is surprising, and indefinite stacking had both taken a large amount of soil, waste resource, caused again serious
Environmental pollution, thus the harmless efficient utilization to slag is extremely the most urgent.
Patent CN 102765914 A discloses that a kind of building waste is non-burning brick or building block and preparation method thereof.Described building
Rubbish is non-burning brick or building block is made up of following raw materials by weight portion: construction waste crushing material 30-57 part, coal gangue particle 25-
