Description
Technical field
The present invention relates to iron tailings stone concrete technical field, more particularly to a kind of system of iron tailings stone pervious concrete
It is standby.
Background technology
Pervious concrete is also known as celluar concrete, non-fine concrete, permeable terrace.Be by aggregate, cement and water mixing and
Into a kind of porous light concrete, it is free of fine aggregate, by coarse aggregate Surface coating a thin layer cement mortar mutually bond and shape
Into the equally distributed alveolate texture in hole, therefore there is the characteristics of ventilative, permeable and in light weight.Iron tailings stone is ore dressing plant discharge
Discarded object of power boiler discharge, its recycling is always the problem of whole society extremely pays close attention to.
Using river sand, rubble, iron tailings sand and iron tailings stone as aggregate, river sand+rubble, CHARACTERISTICS OF TAILINGS SAND+rubble, river sand have studied
Four kinds of aggregates of+tailings stone and CHARACTERISTICS OF TAILINGS SAND+tailings stone combine the influence to concrete shrinkage performance.As a result show, with CHARACTERISTICS OF TAILINGS SAND and
Tailings stone substitutes river sand and rubble, and the influence to concrete shrinkage is different because the strength grade of concrete is different.For C30
With the concrete of C40 strength grades, river sand and rubble are substituted with CHARACTERISTICS OF TAILINGS SAND and tailings stone, the shrinkage factor of its concrete is close or high
In river sand and the shrinkage factor of crushed stone concrete；For the concrete of C50 and C60 strength grades, substituted with CHARACTERISTICS OF TAILINGS SAND and tailings stone
River sand and rubble, the shrinkage factor of its concrete are below river sand and the shrinkage factor of crushed stone concrete.
The content of the invention
In order to overcome problem of the prior art, the present invention provides a kind of preparation of iron tailings stone pervious concrete, and it is not only
Reduce destruction of the exploitation natural stone to ecological environment, and reduce destruction of the iron ore mine stone to environment in itself, it is colored saturating
Water coagulation soil surface is rich in color, may be designed to different patterns according to demand, and color is gorgeous persistently.
The technical scheme is that：A kind of preparation of iron tailings stone pervious concrete, the mass fraction ratio are provided
For：
Preferably, mass fraction 6-36 parts chromatic cementing agent, 250-450 parts cement, 0.9-1.2 part polypropylene fibres are existed
Stirring 20-40s in concrete mixer；Mass fraction 1200-2100 part iron tailings stones, stirring are put into concrete mixer
10-20s, it is well mixed each component；Mass fraction 100-130 parts water is added in concrete mixer and stirred, simultaneously
Observe concrete consistence；Go out machine, carry out the construction of color table surface layer pervious concrete；After the solidification of color table surface layer pervious concrete,
Then homochromy protective agent is sprayed in color table surface layer.
The beneficial effects of the invention are as follows：Destruction of the exploitation natural stone to ecological environment is not only reduced, and reduces iron
The destruction to environment of ore deposit tailings stone in itself, turns waste into wealth, and realizes resource secondary utilization and recycling economy, and there is significant society to imitate
Benefit, colorful water permeable concrete pavement is rich in color, may be designed to different patterns according to demand, and color is gorgeous persistently.
Embodiment

Embodiment 1
18 parts of chromatic cementing agents of mass fraction, 260 parts of cement, 0.9 part of polypropylene fibre are stirred in concrete mixer
Mix 20-40s；1500 parts of iron tailings stones of mass fraction are put into concrete mixer, stir 10-20s, make each component mixing equal
It is even；100 parts of water of mass fraction are added in concrete mixer and stirred, while observe concrete consistence；Go out machine, carry out color
Color table surface layer pervious concrete is constructed；After the solidification of color table surface layer pervious concrete, then sprayed in color table surface layer homochromy
Protective agent.
Embodiment 2
36 parts of chromatic cementing agents of mass fraction, 450 parts of cement, 1.2 parts of polypropylene fibres are stirred in concrete mixer
Mix 20-40s；2100 parts of iron tailings stones of mass fraction are put into concrete mixer, stir 10-20s, make each component mixing equal
It is even；130 parts of water of mass fraction are added in concrete mixer and stirred, while observe concrete consistence；Go out machine, carry out color
Color table surface layer pervious concrete is constructed；After the solidification of color table surface layer pervious concrete, then sprayed in color table surface layer homochromy
Protective agent.
The present invention not only reduces destruction of the exploitation natural stone to ecological environment, and it is right in itself to reduce iron ore mine stone
The destruction of environment, turns waste into wealth, and realizes resource secondary utilization and recycling economy, has significant social benefit, colorful water-permeable mixes
Solidifying soil surface is rich in color, may be designed to different patterns according to demand, and color is gorgeous persistently.
Described above is embodiments of the invention, is not intended to limit the invention, for those skilled in the art,
