Description
Technical field
The present invention relates to a kind of pervious concrete more particularly to a kind of environment friendly pervious concrete of highway engineering.
Background technology
Pervious concrete
Pervious concrete has good ecological ring as a kind of paving material that is novel, having high osmosis
Border benefit.Due to the continuous expansion of modern city, the destruction in the forest of large area, grassland and arable land is caused so that originally good
Property cycle biological and ecological circle by serious destruction, and large area is waterproof, air-locked conventional concrete blocks water road surface
Material is mated formation, and very big pressure is caused to the benign cycle of urban ecological environment.The city " tropical island effect " of getting worse is right
The aqueous vapor in city and the exchange influence of heat are very serious, and since urban architecture is intensive, bituminous paving and concrete cement road surface are white
The heat that it is absorbed is very big, has the specific heat capacity of bigger for soil, and night cooling is slow, and the cooling in outskirts of a town compared with
Soon, in this way since the current of warm air in city rises, the cold airflow in outskirts of a town declines, and has formd outskirts of a town circulation typical, is deposited in air
Various pollutants constantly idle loop is drifted about on city under this local airflow circulating effect, to the ecology in city
Environment and people's health life cause very big harm, lead to the generation of various diseases.Pervious concrete can alleviate city
The development of this " morbid state " in city itself has certain water penetration, and entire pavement system has certain water-retaining property,
Rainwater can penetrate into underground recharge of groundwater by it.This water-permeable and air permeable performance of pervious concrete and the characteristic of soil are very
It is close, and the microorganism in the pavement system of pervious concrete and following soil can be with the nuisance in purifying rainwater
Matter plays the role of cleaning rainwater, and when atmospheric temperature is high, underground water can be evaporated to by water-permeable brick in air, improved
The ecological environment in city.
China has recognized that environmental protection, maintaining ecological balance, walks the importance of sustainable development path, therefore, environmental protection
Ecotypic permeable concrete it is expected to be applied to different kinds of roads and load-bearing road surface, to improve the ecological environment, forms " sponge " city
City.However, the problem of pervious concrete water penetration and intensity contradict, becomes the bottle that pervious concrete is hindered to utilize on a large scale
Neck.Although by using rubber powder, the intensity for improving dispersibility, pervious concrete being improved using composite gel material etc., by
It relies primarily on that coarse aggregate forms larger duct and porosity achievees the purpose that permeable in pervious concrete, therefore, lacks thin collection
Material causes its bonding interface agent small, and intensity raising is extremely limited.It is contour in urban road, highway to limit pervious concrete
The use on load road surface.Even if using fine aggregate, easily there is slurry sinking flowing in cement slurry and fine aggregate in the construction process
Lower part hole is blocked, influences water permeability, this causes great difficulty to the construction of pervious concrete.
Invention content
The present invention provides one kind for the defects of being difficult to control for current pervious concrete intensity difference, bad hydraulic permeability, construction
The environment friendly pervious concrete of highway engineering, including following raw material：Cement, palm ash, coarse aggregate, porosity fine aggregate, fiber increase
Strong agent, SILICA FUME, water.
Preferably, the highway engineering prepared with environment friendly pervious concrete by following raw materials by mass percentage and
Into：Cement 10~40%, palm ash 1~15%, porosity fine aggregate 6~10%, fiber enhancer 3~8%, SILICA FUME 1~
3%th, 5~10% water, surplus are coarse aggregate.
It is further preferred that the highway engineering with environment friendly pervious concrete by following raw material systems by mass percentage
It is standby to form：Cement 10~18%, palm ash 1.8~8%, porosity fine aggregate 6~10%, fiber enhancer 3~8%, micro- silicon
Powder 1~3%, 5~10% water, surplus are coarse aggregate.
Preferably, the cement is portland cement.
Preferably, the palm ash is the ashes after palm shell burning.
Palm ash, mainly by a large amount of silica, potassium oxide, calcium oxide etc. into being grouped as, wherein silica contains
Amount up to 20%~50%, be palm shell be used as fuel after waste, by the use of the solid waste as pervious concrete in
Adhesive has good prospect.Waste this first is very abundant, cheap；Secondly, if the discarding of these wastes can make
Into environmental pollution.Using these wastes, turn waste into wealth, polycyclic guarantor has very important significance.
Meanwhile palm ash, as a kind of porous material, large specific surface area has very high surface energy, according to energy most
Low principle, concrete component will be carried out partial adsorbates by being dispersed in the metallic compound surface in inside concrete space, improve boundary
The bond strength of face adsorption layer improves the properties of concrete, and palm ash can also replace in concrete mixture
Miberal powder kills two birds with one stone.
Preferably, the porosity fine aggregate is porous silicon carbide ceramic particle and/or expanded vermiculite；The porous silicon carbide
The grain size of silicon ceramic particle is 2~4mm；The grain size of the expanded vermiculite is 2~4mm.
As one of which preferred embodiment, the porosity fine aggregate is porous silicon carbide ceramic particle, expanded vermiculite is pressed
Mass ratio 1:1.8 it mixes.
Preferably, the preparation method of the porous silicon carbide ceramic particle is：By SiC powder, Al2O3Powder and graphite are added to
It in ethyl alcohol, is uniformly mixed, green body is pressed into after drying；Green body is put into Muffle furnace and carries out high-temperature calcination, calcining is completed
Postcooling to room temperature obtains porous SiC ceramics piece；Porous SiC ceramics piece is crushed with pulverizer, obtains porous SiC ceramics particle.
Porous SiC ceramics particle has good specific surface area and abundant hole, while strong but also with good structure
Degree.
Expanded vermiculite since it is with good cation exchange and adsorptivity, can improve the structure of concrete, improve
The gas permeability of soil.
Preferably, the fiber enhancer is regenerated polythene fiber and/or regenerating polypropylene fiber；The poly- second of regeneration
Alkene fiber and regenerating polypropylene fiber are respectively that waste polyethylene and discarded polypropylene are prepared；The regenerated polythene fiber
With 1.0~1.5mm of diameter of regenerating polypropylene fiber, length is 20~40mm.
As one of which preferred method, the fiber enhancer is regenerated polythene fiber, regenerating polypropylene fiber is pressed
Mass ratio 1:1.5 it is mixed to get；The regenerated polythene fiber and regenerating polypropylene fiber are respectively waste polyethylene and discard
Polypropylene is prepared；1.0~1.5mm of diameter of the regenerated polythene fiber and regenerating polypropylene fiber, length for 20~
40mm。
At present, China's waste plastic is resourceful, but cannot effectively comprehensively utilize, and the burning of waste plastic is with filling out
It buries, causes environmental pollution, it is very harmful, have become the great difficult problem of society.The present invention moulds waste polyethylene and waste polypropylene
Material is prepared as regenerated polythene fiber and regenerating polypropylene fiber and application in environment friendly pervious concrete, delaying to a certain extent
White pollution problem and problem of environmental pollution, have very important significance to environmental protection cause caused by having solved waste plastic.
Preferably, the coarse aggregate is broken granite；The grain size of the broken granite is 5~7mm.
