Description
Technical field
The present invention relates to preparation and the construction party of pervious concrete technical field, more particularly to a kind of pervious concrete
Method.
Background technology
With expanding economy and the fast development of urban construction, the earth's surface of modern city is progressively by building and impermeable
The air-locked concrete material covering of water, makes Natural Water impermeable to underground, causes ground flora to be difficult to normal growth, cause
Urban surface can not normally adjust humidity and temperature, and produce so-called " tropical island effect ", and precipitation zone comes when also to city rainy season
Drainage system increase pressure, it is impossible to river can only be discharged into by permeating the ground, it is impossible to effectively recharge of groundwater resource.In the recent period, party
Center propose build " sponge city " strategy, should blue montains and green waters, White clouds drift through the blue sky again.Therefore, pervious concrete will be in " sponge
Played a significant role in the construction in city ".
But, by the exploration to prior art and formula, it finds that the water-permeable brick carried out at present is laid and permeable mixed
The preparation construction method of soil is coagulated, there is certain defect.Only pay attention to its water penetration, ignore its compression strength and rupture strength,
Cause the globality on road surface poor.
The content of the invention

The preparation and construction method comprise the following steps：
Step one, adhesive specially is prepared according to said ratio；
Step 2, using aggregate surface pack, is put into container by the water of stone and proportioning 50% by proportioning and stirs in advance, pre- stirring
Time is 1min；
Step 3, adhesive specially is added by proportioning, and is slowly added to remaining water, is sufficiently stirred for 3 ~ 5min, obtains sticky, nothing dry
Material and the uniform pervious concrete slurry without from wash rice；
Step 4, the pervious concrete slurry obtained after being sufficiently stirred for is laid on roadbed, using low frequency vibrator or rolling
Device pressurization jolt ramming, and carry out polishing processing using sanding machine before concrete initial set；
Step 5, overlay film water seasoning is no less than 7 days；
Step 6, by inorganic pigment and adhesive specially according to parts by weight 1:1 mixing, and 6 ~ 7 parts of water of addition, stirring 2 ~
3min, forms spray coated paint；
Spray coated paint, pervious concrete surface is uniformly sprayed at using flush coater by step 7, and every square metre is consumed 80 ~ 100 grams
Spray coated paint, a variety of colors and style can be sprayed as needed；
Step 8, pervious concrete surface carries out resin cover processing after being completely dried, and cover is used as by the use of oiliness acrylic resin
Face agent, 1 is pressed by acrylic resin and organic diluent；1 ratio is well mixed, and is sprayed into pervious concrete surface, to strengthen
The colour vividness of colored road surface and the durability of pigment, 150 ~ 180 grams of cover agent of every square metre of consumption.
This programme adds silicon powder and re-dispersible glue powder in pervious concrete, is effectively improved the resistance to compression of the product
Intensity, rupture strength and freeze-thaw resistance index, so as to improve the durability of the concrete；Added in pervious concrete efficient
Water reducer and calcium formate, can improve the workability of concrete, improve its early strength；By added with rubber powder formula and change
Construction method uses aggregate surface pack, can effectively improve cohesive strength of the cement slurry to stone aggregate, promotes cement slurry
Preferably package aggregate stone, strengthens it and wraps up power, so as to improve product compression strength and durability.
As optimization, SiO2 purity ＞ 85% in the silicon powder.Fully ensure that the compression strength of pervious concrete.
It is used as optimization, the mesh of fineness ＜ 100 of the re-dispersible glue powder.Fully ensure that the freeze-thaw resistance of pervious concrete refers to
Mark.
As optimization, the water reducer is naphthalene system FDN.Used cooperatively with calcium formate, it is further improvement concrete and easy
Property, improve its early strength.
It is used as optimization, the purity ＞ 93% of the calcium formate.Used cooperatively with water reducer, further improve the sum of concrete
Yi Xing, improves its early strength.
Beneficial effects of the present invention are：By adding the innovation of polymer and construction technology, effectively change permeable mixed
The performance of soil is coagulated, the water penetration of pervious concrete had both been met, its compression strength and rupture strength is met again, its freeze thawing resistance energy
Power reaches relative national standards.
