Description
Technical field
The present invention relates to a kind of concrete technology of preparing more particularly to a kind of multiple fly ash and miberal powder pervious concrete
Preparation and application.
Background technique
With the acceleration of urbanization process, urban road is gradually covered by concrete, since asphalt concrete is impermeable
Gas, waterproof, earth's surface is difficult to carry out heat exchange with atmosphere, and some researches show that the tropical island effects in city to aggravate year by year, due to city
Drainability is limited, through often being there is large area ponding after rain, and then urban waterlogging phenomenon occurs, thus will lead to traffic paralysis with
The loss of people's property.In order to improve the comfort level of people's life, permeable, the ventilatory problem of urban pavement, people's research and development are solved
Pervious concrete out, pervious concrete have excellent ventilative, water permeability can if can preferably be applied to urban pavement
Largely improve above-mentioned phenomenon.It not only can solve urban road Quick drainage problem, but also ground water circulation can be promoted,
Rainwash is purified, is improved the ecological environment.
Pervious concrete has been typically free of fine aggregate, is mainly mutually bonded by cementitious material cladding microlith, permeable mixed
Solidifying soil is in uniform honeycomb shape, its porosity is larger compared with normal concrete, therefore is mainly used in park pavement, parking
Field, greenbelt, city square etc. to improvement urban area tropical island effect, reduce rainwash and water resources governance, promotion city
Air circulation has obvious effect.But it is mutually bonded between pervious concrete aggregate mainly by cementitious material, because its porosity is general
All 20% or so so compression strength is lower, the service life of concrete is reduced.

Below by drawings and examples, technical scheme of the present invention will be described in further detail.
Detailed description of the invention
Fig. 1 is the flyash of preparation and the application of a kind of multiple fly ash of the embodiment of the present invention and miberal powder pervious concrete
Mix the relational graph of ratio and concrete strength again with miberal powder.
Specific embodiment
Below with reference to attached drawing, the invention will be further described, it should be noted that the present embodiment is with this technology side
Premised on case, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to this reality
Apply example.
Structure of the invention, including following raw material components weighed by weight: 200~390 parts of ordinary portland cement, thin
1300~1700 parts of stone, 24~108 parts of miberal powder, 12~96 parts of flyash, 3.5~5.5 parts of additive, 80~120 parts of water；
Wherein, microlith is common microlith and reinforcing dry slag；The preparation method for strengthening dry slag includes: by weight 1:
0.15~0.25:0.8~1.3:0.6~0.8:0.01~0.02 in addition weigh common dry slag, water, ordinary portland cement,
Fine sand and water-reducing agent, and the clay content of common dry slag is no more than 1%；First by water, ordinary portland cement, fine sand and water-reducing agent
It is mixed into dilute high-strength mortar, then common dry slag is poured into dilute high-strength mortar and is stirred, after one layer of high-strength mortar to be wrapped,
Leach be cooled to common dry slag surface high-strength mortar hardening, the reinforcing dry slag being finally made, gradation be 5~
25mm；
In additive component, silicon ash: bentonite: latex powder: water-reducing agent ratio by weight is 4~10:0.5~0.8:0.5
~0.8:0.1~0.3.
Preferably, the present embodiment includes following raw material components weighed by weight: 250~300 parts of ordinary portland cement,
1600~1650 parts of microlith, 40~50 parts of miberal powder, 60~80 parts of flyash, 3~5 parts of additive, 90~100 parts of water.
Further, the present embodiment includes following raw material components weighed by weight: 280 parts of ordinary portland cement, thin
1620 parts of stone, 48 parts of miberal powder, 72 parts of flyash, 4 parts of additive, 96 parts of water.Fig. 1 is that the embodiment of the present invention one kind mixes fine coal again
The flyash and miberal powder of preparation and the application of ash and miberal powder pervious concrete mix the relational graph of ratio and concrete strength again, such as scheme
Shown in 1, when flyash and miberal powder ratio are in 6:4,28d compression strength reaches maximum value 32.2MPa.To find out its cause, cement water
A large amount of alkalinity Ca (OH) 2, pH is generated after change can reach 12, can excite the active material in flyash and miberal powder, generate fine and close
Hydrated product C-H-S gel and a small amount of AFt, the gap that filling concrete is generated by aquation.Miberal powder hydrated product aggregation simultaneously
Around fly vitreous, the heat evolution velocity that nucleus promotes flyash can be used as.In addition the ratio table of cement, flyash, miberal powder
Area is sequentially increased, and can form dense-packing effect between three kinds of cementitious materials, and a small amount of unhydrated particle can be used as micro-aggregate
It is filled, reduces the porosity of system, keep hardenite intensity higher.When contents of ground slag is excessively high, cement mixing content is opposite is reduced,
In a short time miberal powder and flyash can not complete aquation, hydrated product is opposite to be reduced, so table mutually goes out compression strength and reduces.So multiple
The ratio of flyash and miberal powder is advisable in 6:4 when mixing two kinds of mineral admixtures.
Ordinary gravel and the weight ratio of reinforcing dry slag are 0.7~1.5:1 in microlith.
Ordinary gravel and the weight ratio of reinforcing dry slag are 1.2:1 in microlith.
In the preparation method for strengthening dry slag, weighed common dry slag, water, ordinary portland cement, fine sand and diminishing
The weight ratio of agent is 1:0.2:1.1:0.8:0.02.
Preparation step includes:
S1, ordinary portland cement, miberal powder, flyash, additive and water are weighed, stirs and evenly mixs to obtain cement mortar；
S2, microlith mixing is added in cement mortar, obtains concrete semi-finished products after molding hardening；
S3, by concrete semi-finished products sprinkling maintenance at room temperature, obtain concrete finished product.
Therefore, the preparation and application of the multiple fly ash and miberal powder pervious concrete of the present invention using the above structure, works as powder
In 6:4,28d compression strength reaches maximum value 32.2MPa for coal ash and miberal powder ratio, can meet basic requirement at this time,
And significantly save production cost.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than is limited,
Although the present invention is described in detail with reference to preferred embodiments, those skilled in the art should understand that: its according to
So can be with modification or equivalent replacement of the technical solution of the present invention are made, and these modifications or equivalent replacement cannot also make to repair
Technical solution after changing is detached from the spirit and scope of technical solution of the present invention.
