Description
Technical field
The present invention relates to the field of building materials, are specifically related to a kind of pervious concrete blind way dedicated mortar.
Background technique
Sponge urban construction at present is national strategy, and fundamental policy is to improve natural environment, the great thing to promote the well-being of mankind
Industry, pervious concrete road are the important links of sponge urban construction, it can solve city " tropical island effect ", seep natural water
Enter underground, recharge of groundwater resource prevents urban waterlogging, the vital measure of extreme influence people life.
Pervious concrete blind way mortar is to be laid with blind person channel in pervious concrete surface layer, seeks the well-being of for disabled person
Social welfare cause, be after the permeable pavements engineerings such as pervious concrete, pitch pervious concrete, water-permeable brick project expand with
Extend, the inevitable achievement for promoting pervious concrete engineering to develop to breadth and depth.However, obtained based on Bartlit
Water coagulation soil blind way mortar is more or less defective, it is difficult to take into account high-intensitive, wear-resisting, freeze thawing resistance, cracking resistance, colour, cohesiveness, guarantor
The performances such as aqueous and workability.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of good permeable coagulation of comprehensive performance
Native blind way dedicated mortar, alternative Bartlit are broken the paving process of traditional blind way, are benefited for individuals with disabilities, and the product is strong
High, wear-resisting, freeze proof, cracking resistance, environmental protection are spent, has stronger performance, while having stronger cohesiveness, water-retaining property, workability, operation spirit
It is living easy, it is easy to construction molding, it is beautiful in colour, it is beautiful and generous.
To achieve the object of the present invention, according to parts by weight, pervious concrete blind way dedicated mortar of the invention includes
70-90 parts of machine material, 0.3-0.8 parts of water-reducing agent, 0.2-0.5 parts of fiber, 2-6 parts of toner, 0.1-0.5 parts of air entraining agent, surely mould agent
0.1-0.5 parts, 0.2-0.6 parts of plasticity-maintaining agent, 0.5-1 parts of silica.
Preferably, according to parts by weight, pervious concrete blind way dedicated mortar includes 80 parts of organic material, water-reducing agent
0.5 part, 0.35 part of fiber, 4 parts of toner, 0.3 part of air entraining agent, steady 0.3 part of agent, 0.4 part of plasticity-maintaining agent, 0.7 part of silica of modeling.
Further, the organic material is the natural fine sand of 1.6-1.8, oxidation comprising portland cement, fineness modulus
Calcium clinker, rice hull ash and modified alta-mud.
Preferably, portland cement, natural fine sand, calcium oxide that fineness modulus is 1.6-1.8 are ripe in the organic material
The mass ratio of material, rice hull ash and modified alta-mud is 3-5:(8-10): 1:(2-3): (2-3).
Further, the modified alta-mud is obtained by following steps: pressing bentonite: 10% citric acid water: sodium metaaluminate
The mass ratio 2-3:1-2:1 of solution is uniformly mixed, and investment is ultrasonically treated 40-55min into processor for ultrasonic wave, is then allowed to stand 8-
10h, filtering are warming up to 550-600 DEG C after drying filter cake, keep the temperature 1-2h, cooling, grinding, cross 100-200 mesh to get changing
Property bentonite.
Further, the water-reducing agent is low entraining type ethers polycarboxylate powder water-reducing agent, and water-reducing rate is greater than 25%,
Normal pressure Qinshui rate ratio is less than 20%.
Further, the fiber is lignocellulosic.
Preferably, the lignocellulosic is modified lignin resin fiber, and preparation method includes the following steps: by weight
Meter, by the lignin fibre of 70-75 parts of drying and crushings, 2-3 parts of ACR resin emulsions, 1-2 parts of barium metaborates, 2-3 parts of alkylphenols
Polyoxyethylene ether, 30-45 parts of ethylene glycol after mixing, are put into kneader, mediate 1-2 hours under the conditions of 60 DEG C -70 DEG C.
Preferably, the toner is yellow powder.
Further, the air entraining agent be rosin tree lipid, fatty alcohol sulfonate class, alkylated aromatic sulfonic acid class air entraining agent,
And the air entraining agent 1h air content ongoing change amount is -1%~+1%；The setting time of air entraining agent poor -60~+60min；Bleed
Air content >=3% of agent；Bleeding rate ratio≤65% of air entraining agent.
Further, the steady modeling agent is lignosulfonates.
Further, the plasticity-maintaining agent is sodium gluconate, citric acid, minimum one kind in sodium tripolyphosphate.
It is easy to operate using live mold production when pervious concrete blind way mortar of the invention is built for blind way, no
Pollute environment, and beautified traffic, be the perfect combination of Man & Nature, can substitute completely traditional lithotome, granite and
Other blind way products solve nature stone material and excessively develop the status for destroying ecological environment and natural stone resource scarcity, and solve
Bonded floor surface mat formation cannot be permeable problem.Pigment is added in mortar, produces the fine scene of blind way as rainbow.
Compared with prior art, advantages of the present invention is mainly reflected in:
1. pervious concrete blind way mortar, with intensity height, wear-resisting property is good, cracking resistance is freeze proof, meet the permeable function of pervious concrete
Energy demand, and it is beautiful and generous, and blind person's walking is felt good, and blind way functional requirement is complied fully with；
2. substitution lithotome completely, reduces the wasting of resources, conservation of nature environment, change that lithotome cannot be permeable is asked
Topic；
3. mold production and construction technique is used, it is easy to operate, big machinery is not used, and can be completely hand-manipulated, saving of labor saves
When, economic benefit is obvious, and blind sense is full；
4. the blind way mortar ratio ordinary mortar presetting period shortens, the ordinary mortar presetting period is 150 minutes, by the technology of the present invention side
The case resulting blind way mortar presetting period be no more than 60 minutes, for rapid construction demould provide possibility, improve construct into
Degree, creates more construction times and convenience.
