Description
Technical field
The invention belongs to the field of building materials, specifically disclose a kind of recycled fine aggregate non-light tight concrete and preparation method thereof.
Background technique
Non-light tight concrete as a kind of novel decorative concrete, broken conventional concrete it is dull, heavy, huge to people,
Dull feeling assigns the characteristics such as concrete light, active, flexible and changeable, beautiful.Currently, non-light tight concrete is public
The fields such as building, interior decoration, sculpture, craftwork are applied, and achieve good effect.Non-light tight concrete is made at present
In standby technology, generally use artificial sand/natural sand as fine aggregate, this constitutes a kind of new consumption to natural sand stone resource, especially
It is today very in short supply in sand and stone resources, is merit attention the problem of.If people can be substituted using a kind of obsolete material
Work sand/natural sand prepares the non-light tight concrete for meeting performance requirement, not only can solve above-mentioned sand and stone resources consumption problem, but also
It can be with resource utilization obsolete material.
Along with the development of China's urban construction, the scale of China's urban building waste also constantly expands, and city is built now
The annual emissions of building refuse have reached 400,000,000 tons, are limited by application technology and approach, these building wastes mostly use air storage
Formal layout, the overwhelming majority there is no resource utilization.Wherein, tear down and reconstruct build concrete be urban building waste it is main at
/ mono-.Therefore, proposition of the present invention prepares a kind of recycled fine aggregate non-light tight concrete, builds concrete using broken tear down and reconstruct and replaces
Non-light tight concrete is prepared as fine aggregate for artificial sand/natural sand, advantageously accounts for traditional non-light tight concrete to natural sand stone resource
The problem of consumption, while building the resource utilization of concrete to be torn down and reconstructed in urban building waste one new way is provided.
Summary of the invention
