Description
Technical field
The present invention relates to technical field of road construction, more particularly to a kind of resistance to compression steel fiber reinforced concrete.
Background technology
With the propulsion of Process of Urbanization Construction, the exploitation of water-permeable pavement improves the ever more important that seems, helps solve deep layer
Secondary urban ecological problem.Current porous pavement mainly has water-permeable brick, pervious concrete and emerging polyurethane rubble permeable
Road surface.Preferable durability can be obtained using the Polyurethane cement mortar of the identical ratio of mud.
The more common concrete strength of polyurethane concrete is relatively low, in order to improve its intensity, can often add in blending process
Add a certain amount of naphthalene series high-efficiency water-reducing agent, so as to avoid it from occurring larger because external force is excessive in process of setting after pouring
Deformation, but after using naphthalene series high-efficiency water-reducing agent, the slump increase of concrete,《Mixed mud and cement products》Disclosed in
" Na in water reducer2SO4Influence of the content to concrete performance " is pointed out, can reduce coagulation by improving the content of sodium sulphate
The slump numerical value of soil, after sodium sulphate is more than 10% in water reducer, the fluidity of concrete reduces especially at 35%, collapses
Number of degrees value reduces, but at the same time, the resistance to compression value of mixed mud has also declined.
The content of the invention
In view of the deficienciess of the prior art, the invention provides a kind of resistance to compression steel fiber reinforced concrete, it is in naphthalene system diminishing
Under sodium sulphate effect, mobility reduces, and avoids slump numerical value excessive for agent, and then the workability of concrete improves, not only such as
This, under steel fibre and silica flour effect, has larger compressive property.
To achieve the above object, the invention provides following technical scheme：A kind of resistance to compression steel fiber reinforced concrete, with parts by weight
Component meter, including following component：Cement 22-25 parts, filler 10-12 parts, rubble 80-120 parts, fine sand 60-80 parts, naphthalene system subtract
Aqua 0.4-0.6 parts, synergist 0.15-0.3 parts, water 16-18 parts, sodium sulphate 0.06-0.1 parts, steel fibre 20-30 parts.
Pass through above-mentioned technical proposal, increase the sulfur acid sodium amount of naphthalene water reducer by adding sodium sulphate first, so as to drop
The mobility of the low concrete using naphthalene water reducer, then by adding the compressive property of steel fibre raising concrete, steel fibre
Concrete is that a kind of new heterogeneous composite material that the short steel fibre of random distribution is formed is mixed in normal concrete, this
The steel fibre of a little random distributions can effectively hinder the extension of inside concrete microcrack and the formation of macrocrack, significantly
Tension, bending resistance, shock resistance and the anti-fatigue performance of concrete are improved, there is preferable ductility.
Of the invention further, the steel fiber surface is coated with zinc layers.
Pass through above-mentioned technical proposal, because excessive sulfate ion can corrode to steel fiber surface, and it is fine in steel
Dimension table face is coated with zinc layers, it is possible to increase the corrosion resistance of steel fibre, the integrality for maintaining steel fibre is finally reached, so as to maintain
Concrete has certain structural strength, and resistance to compression effect is strong.
It is of the invention further, in terms of parts by weight of component, in addition to silica flour 6-8 parts.
Pass through above-mentioned technical proposal, although the steel fibre of addition improves the intensity of concrete, the content of steel fibre
When too high, larger space is formed between cement, causes intensity decreases on the contrary, therefore filled out using a certain amount of silica flour
Fill so that steel fiber reinforced concrete is more closely knit, and anti-pressure ability can be improved further.
It is of the invention further, in terms of parts by weight of component, in addition to polypropylene fibre 3-6 parts.
Pass through above-mentioned technical proposal, excessive sodium sulphate can not only cause to corrode to steel fibre, and can be to concrete certainly
Body corrodes, and surface easily produces depression, and inside easily hole occurs, is admixed, can substantially changed using polypropylene fibre
It is kind.
It is of the invention further, in terms of parts by weight of component, in addition to calcium chloride 2-3 parts.
Pass through above-mentioned technical proposal, in the winter time, it is difficult to solidify after having poured concrete, and the calcium chloride added can speed up
The solidification of concrete.
It is of the invention further, in terms of parts by weight of component, in addition to carboxylic styrene butadiene latex 6-10 parts.
Pass through above-mentioned technical proposal, concrete is modified by carboxylic styrene butadiene latex, it is possible to increase concrete resists
Jelly property so that in the winter time, under external pressure, the phenomenon of cracking is less likely to occur concrete.
Of the invention further, the filler is flyash or volcanic ash.
Pass through above-mentioned technical proposal, Cab-O-sil, flyash and volcanic ash belong to fine powder, on the one hand can improve the close of aggregate
It reality, on the other hand can improve the workability of concrete, reduce liquid-solid ratio, improve polyurethane concrete intensity.
In summary, the present invention improves the sodium sulphate content in water reducer mainly under the conditions of naphthalene water reducer, so as to
Enough so that the mobility of concrete reduces, avoid slump numerical value excessive, and then the workability of concrete improves, moreover,
Under steel fibre and silica flour effect, there is larger compressive property；In addition, the calcium chloride and carboxylic styrene butadiene latex that add are in severe cold
Under conditions of each contribute to concrete, protect its integrality.
