Example are as follows: by weight, SILICA FUME: nano silica=2: 1.It is highly preferred that organic enhancing group be divided into water-reducing agent, latex powder,
One of modified polyethylene glycol oxide, triethanolamine are a variety of, and water-reducing agent is naphthalene water reducer, melamine water reducing agent, polycarboxylic acids
One of based water reducer.
Preferably, fugitive dust group is inhibited to be divided into ARBOCEL range of functional wood fibre.German JRS company production.
Preferably, thixotropic lubricant is compounded by starch ether and hydrated magnesium silicate, compound proportion are as follows: by weight, is formed sediment
Powder ether: hydrated magnesium silicate=(1~2): 1；Wherein starch ether is one of hydroxypropyl starch ether or carboxymethyl starch ether.Hydration
Magnesium silicate is the pangel series of products of Hong Kong Hai Yi enterprise development Co., Ltd agency, and production unit: Spain TOLSA is public
Department.
Compared with prior art, of the invention to have the advantages that
(1) environment friendly and pollution-free, pure inorganic material is homogenized, and has many advantages, such as intensity height, good water permeability；
(2) cohesive force between stone and stone can be increased substantially, under the premise of guaranteeing effective drainage porosity significantly
Improve permeable coagulation compression strength；
(3) wrapped excellent, it can be sufficiently wrapped in stone surface, do not trickled, do not precipitated, gap between stone will not be blocked；
(4) generation of dust can be reduced by most of granular absorption on the surface of wood fibre.
Specific embodiment
A kind of dustless binder of pervious concrete green, by weight, including the component in such as the following table 1:
Table 1
Latex powder is the 5010N of Wa Ke company production.Hydrated magnesium silicate is Hong Kong Hai Yi enterprise development Co., Ltd agency
Pangel AD.Functional wood fibre is the ARBOCEL LD of JRS company, Germany production.Polycarboxylate water-reducer be Suzhou not
The C900 of gram Science and Technology Ltd. production.Other above all raw materials are commercial product entirely.
The preparation method of above-described embodiment one to three is: weighing various raw materials by said ratio, then mixes in blender
It closes, stirs evenly.
By the binder of the proportion production of above-described embodiment one to three, by binder: stone: water=2: 8: (0.65~0.70)
Ratio, batch weighing stirring, stir 5min after carry out performance detection.Wherein cobble-stone diameter is 5~10mm.
Coefficient of permeability, compression strength, porosity are by CJJ/T135-2009 " water-permeable cement concrete pavement technique regulation "
Regulation carries out test powder.Through detecting, the product compression strength is high, has good workability, gap is uniform, and slurry is not sunk to the bottom, water penetration
It can be excellent.
Its physical property see the table below 2:
Table 2
Dust number is measured using " Dust View " dust measurement of PALAS company production, after dust number=0.5S
Value+30S after value.Commercial product pervious concrete sample is compared with the embodiment of the present invention, specific data such as following table,
Know that dust of the present invention reduces amplitude and reaches 50% or more by data, anti-dust effect is excellent.
Table 3
| Detection project | Commercial product | Embodiment one | Embodiment two | Embodiment three |
| Dust number | 110.2 | 55.3 | 58.6 | 61.3 |
Working principle of the present invention:
Above-mentioned pervious concrete applies following technologies with the dustless binder of green:
1, enhance
The present invention is combined using micro-nano powder body material modification technology and water reducing and strength increasing technology, that is, utilizes micro-nano powder
The filing effect and volcano ash effect of material, improve the compactness of pervious concrete；It is reduced simultaneously using high efficiency water reducing agent entire
System water consumption, reduces the presence of free water, to improve the intensity of pervious concrete.
2, application property
Because in pervious concrete work progress, slurry is easy to sink to the bottom, gap is blocked, reduces ground water penetration, the present invention must
Must have water conservation, the anti-construction property hung from above.To reach this purpose, the present invention is compounded by a variety of water-keeping thickening materials, makes it
With low viscosity, the characteristic of Gao Baoshui.Starch ether and hydrated magnesium silicate compounding, that is, can be improved mortar water-retaining property, and solve
It is anti-to hang performance from above.Hydrated magnesium silicate belongs to phyllosilicate one kind, is made of two layers of tetrahedral silicon dioxide unit, leads to
It crosses a central Oxygen atom and one layer of discontinuous magnesium atom octahedron connects composition.This structure has hydrated magnesium silicate
There is microfibre acicular texture, acicular texture makes it have very effective absorption property, so that highly viscous product suspension has
There are thixotropy and pseudoplastic behavior.
3, dustless
The present invention can reduce pervious concrete shrinking percentage using the functional wood fibre of JRS company, Germany production, extend
Development time reduces cracking, improves sag resistance and anti-caking function, at the same by most of granular absorption wood fibre table
The generation of dust is reduced in face.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
