Description
Technical field
The invention belongs to civic building highway technology field, and in particular to a kind of civic building engineering pavement concrete.
Background technology
At present, highway pavement material mainly has two kinds of bituminous concrete and cement concrete in China's civic building engineering,
Asphalt concrete pavement has the advantages that flatness is high, road-ability is good, simple maintenance, but there is also by amblent air temperature
Influence big, summer high temperature season non-deformability is poor, easy embrittlement cracking and the problems such as poor durability during winter low temperature.Cement
Concrete road surface has that service life is long, maintenance work amount is small, resource consumption is few, easy construction, Traffic volume level and environment is fitted
The advantages that Ying Xingqiang.But normal concrete is a kind of typical fragile material, and bending tensile strength is low with deformability, therefore cement
Concrete road surface fragility is big, road-ability is poor, shock resistance and anti-fatigue ability are weak, easy brittle failure, easily occurs surface knot too early
Structure destroys.
The content of the invention
The problem of present invention is individually present for above two material, there is provided one kind has bituminous concrete and coagulating cement concurrently
The civic building engineering pavement concrete of native advantage, have the performances such as high tenacity, shock resistance, cracking resistance, wear-resistant, antiskid excellent
Gesture.To reach above-mentioned purpose, the present invention uses following technical scheme, a kind of civic building engineering pavement concrete, by following
The raw material composition of parts by weight：Portland cement 60-100 parts, amorphous state C 12 A 7 3-5 parts, modified emulsifying drip
Blue or green 20-30 parts, natural wollastonite in powder 4-8 parts, composite fibre 1-4 parts, defoamer 0.01-0.08 parts, water reducer 0.5-2 parts, sand
10-20 parts, stone 20-40 parts, water 20-30 parts.
The modified emulsifying asphalt be by matrix pitch, compound emulsifying agent and polymer emulsion through high speed shear prepare and
Into.
Preferably, the compound emulsifying agent is by bromination trimethyloctadecyl ammonium, chlorodimethyl double dodecyl ammonium, 2-
One kind and tertiary amine-type in triethylene tetramine methylene -4- nonyl phenols, iodate trimethyl-perfluorinated octyl sulfuryl amine propyl ammonium
Wooden amine asphalt emulsifier is combined.
It is furthermore preferred that the compound emulsifying agent is wooden by iodate trimethyl-perfluorinated octyl sulfuryl amine propyl ammonium and tertiary amine-type
Amine asphalt emulsifier is combined.
The polymer emulsion is one in Carboxy emulsion, VAE emulsions, water based epoxy vinylacrylic acid emulsion
Kind.
The natural wollastonite in powder fineness is 600-800 mesh.
The composite fibre is made up of polyacrylonitrile fibre, polyurethane fiber and brucite fiber.
The defoamer is in polypropylene glycerol aether, dimethyl silicone polymer, tributyl phosphate and dibutylphosphoric acid ester
It is a kind of.
The water reducer is polycarboxylate water-reducer.
The sand is washed-out sand, modulus of fineness 2.6-2.8.
The stone is 5-25mm continuous gradings.
Modified emulsifying asphalt in the present invention makes polymer particle be combined with bitumen particle, formed under Strong shear effect
It is emulsified the polymer-asphalt particulate of agent molecule encapsulating.The surface-active substances such as iodate trimethyl-perfluorinated octyl sulfuryl amine propyl ammonium
Matter can be adsorbed on pitch particle and water termination, significantly reduce pitch and the free energy of water termination, form it uniform and stabilization
Emulsion.Because some surface reactive materials contained in modified emulsifying asphalt have deferred action, hydrated cementitious can be delayed, make water
Mud condensation cure time lengthening, amorphous state C 12 A 7, internal particle are in No- L aw Order, without certain geometry outside
Shape, activity is higher, can accelerate hydrated cementitious setting rate, shortens setting time, when hydrated cementitious is accelerated, consumes substantial amounts of water
Divide the de-emulsification speed for also accelerating emulsified asphalt, the IPN network of formation.Composite fibre can improve the crack resistance of concrete,
Natural wollastonite in powder has pin, Rod-like shape structure, the three-dimensional random distribution in system, can also improve the crack resistance of material
Can, both, which act synergistically, makes that concrete pavement performance of the present invention is more balanced, and cost performance is higher.Made by the collaboration of various materials
With significantly improving the fragility of cement concrete, make concrete of the present invention that there is good toughness and ductility, improve municipal administration and build
Build engineering pavement concrete shock resistance.
The invention has the advantages that：
(1) surfactant in the present invention in modified emulsifying asphalt can significantly reduce the surface tension of system, make water
Mud quickly, can be mixed uniformly with pitch, and hydrated cementitious and the synchronous progress of pitch demulsification, both combine closely to form half firm half
Soft pavement structure.
(2) civic building engineering of the present invention is formed with pavement concrete by organic-inorganic Material cladding, is had high tenacity, is resisted
The performance advantage such as impact, cracking resistance, wear-resistant, antiskid.
