Description
Technical field
The present invention relates to sewerage system field, particularly relate to a kind of polymer for building sponge city permeable mixed
Solidifying soil.
Background technology
Sponge city refers to that city can have adapting to the aspect such as environmental change and reply natural disaster as sponge
Good elasticity, water suction, water-retention, infiltration, water purification when raining, the water release that will store when needing, and be used.City at present
Road footpath, square many employings water-permeable brick or pervious concrete mat formation solution permeable under ooze problem.For giving thoroughly to concrete
Water function, former xoncrete structure need to change the density of concrete makes water-permeable brick or pervious concrete frost resistance by the biggest shadow
Ring, the highest for solving frost resistance defective product construction cost per square meter cost.If current Anhui Chizhou City, jiangsu wuxi etc. are in July, 2015
Mat formation the most cracking, surface layer of footpath, square many employings water-permeable brick material or the pervious concrete material just implemented takes off
The frost resistance difference problem such as fall and lose water seepage function.
Summary of the invention
It is an object of the invention to provide a kind of polymer pervious concrete for building sponge city, above-mentioned to solve
Technical problem.
The technical problem to be solved realizes by the following technical solutions:
A kind of polymer pervious concrete for building sponge city, it is characterised in that every cubic metre containing the most former
Material:
Cement 370～420kg；
Rubble 1500kg, ballast grain sizes is 5～10mm；
The silica sand of particle diameter 0.5mm, consumption is the 5%～10% of cement weight, and silica sand particles is oval；
Mixing intensity reinforcing agent, consumption is the 5%～8% of cement weight；
Water, water is 1:0.27～1:0.33 with the weight ratio of cement；
Polymer compound formulation, consumption is the 3% of cement weight；
Described polymer compound formulation is to be formed by the raw material mixture of following weight proportion:
Epoxy resin 12 parts, chlorinated paraffin 0.6 part, montmorillonite powder 1.6 parts, polyacrylamide 1.2 parts, acrylic acid-acrylic
Acid hydroxypropyl acrylate copolymer 0.3 part.
Described mixing intensity reinforcing agent is by weight forming for 1:8 mixture by water reducer, silicon ash.
Utilize the method that above-mentioned polymer pervious concrete prepares polymer water-permeable pipe:
1. peace ratio requirement is configured to polymer pervious concrete；
2. installation mold；
3. mounted mould is moved to vibration platen；
4. being poured to mould by the polymer pervious concrete prepared, vibration limit, limit feeds intake；
5. together with mould, the water-permeable pipe poured being moved into steam-cured room, utilize steam steam-cured, steam temperature is 115 DEG C,
Steam-cured is 1.5 hours；
After the most steam-cured end, the demoulding；Steam curing 35mi n, steam temperature is 103 DEG C；
7. remove steam-cured room, stack.
Pervious concrete shaping structures has three kinds of duct forms: unimpeded space, half unimpeded space and dead air space, Qi Zhongfeng
Close space and half unimpeded space all to provide for water penetration and support, concrete strength can be caused on the contrary to reduce.Select simple grain level
Join rubble, the strict size controlling simple grain rubble and the oval rubble of selection, can make to be formed during pervious concrete shaping structures
Half unimpeded space and dead air space greatly reduce, unimpeded space is increased, thus improves water permeability.
Make cement slurry viscosity increase after cement introduces polymer, improve the attachment that cement wraps up around rubble
Power, when vibration moulding, cement does not falls off, it is to avoid duct closed by cement mortar, improves unimpeded pore volume, thus improves permeable
Performance.
After cement introduces polymer, Behavior of Hardened Cement Paste rigidity can be changed, make the Behavior of Hardened Cement Paste of formation have certain flexibility, improve anti-
Deformability, thus improve frost resistance.
The addition of mixing intensity reinforcing agent, it is possible to reduce the ratio of mud of concrete, is filled with the space forming Behavior of Hardened Cement Paste, carries
The high compactness forming Behavior of Hardened Cement Paste, thus improve frost resistance.
The invention has the beneficial effects as follows:
The present invention provides a kind of polymer pervious concrete for building sponge city, and half produced in forming process is smooth
Logical space and dead air space are few, and unimpeded space is many, and water permeability is good, and intensity is high；The polymer introduced, makes Behavior of Hardened Cement Paste have one
Fixed flexibility, non-deformability is good, has preferable anti-freezing property.
