Abstract
The present invention relates to a kind of pervious concrete, fraction proportioning by weight is made up of following components：106 parts of cement, 35 parts of lime stone matter stone flour, 33 65 parts of aggregate, 12 24 parts of iron powder, 22 27 parts of macroreticular resin, 49 parts of sulfurous acid sodium powder, 10 30 parts of adhesive, 12 15 parts of reinforcing fibre, 150 180 parts of cobblestone, 12 parts of foaming agent, 12 parts of additive.The advantage of the invention is that：The pervious concrete of the present invention substitutes the coal dust in original formula using lime stone matter stone flour, greatly alleviates the dependence to coal dust, reduces the production cost of concrete, improve economic benefit.
Description
Technical field
The present invention relates to concrete manufacturing field, more particularly to a kind of pervious concrete.
Background technology
With the development of concrete technology, maintaining ecological balance and realize that sustainable development is also chasing after for building material field
Seek target.Pervious concrete is a kind of environmental environment-friendly concrete.Existing certain intensity, there is certain water-permeable and air permeable again
Property, using pervious concrete, moisture can permeate the ground quickly, road the rainy day will not ponding, reflective, so as to alleviate well
The waterproof influence to caused by environment of mating formation.
Pervious concrete is typically made up of cement, coarse aggregate, water and additive.In recent years, answering due to pervious concrete
With advantage, people have done substantial amounts of research to this.For example, CN101190833A discloses a kind of pervious concrete and its preparation side
Method, the formula for the pervious concrete that the patent provides：Cement, aggregate, water reducer and adhesive etc. form.CN101857403A is public
A kind of pervious concrete is opened, it is formulated：Cement, latex powder etc. form.It is but permeable mixed prepared by the formula of prior art
The performance indications for coagulating soil are not highly desirable, do not reach good water penetration, it is impossible to meet engineering demand.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of pressure resistance with good compression strength and coefficient of permeability
The pervious concrete of degree.
In order to solve the above technical problems, the technical scheme is that：A kind of pervious concrete, its innovative point are：Press
Weight fraction proportioning is made up of following components：
106 parts of cement, 35 parts of lime stone matter stone flour, aggregate 33-65 parts, iron powder 12-24 parts, macroreticular resin 22-27 parts, sulfurous acid
Sodium powder 4-9 parts, adhesive 10-30 parts, reinforcing fibre 12-15 parts, cobblestone 150-180 parts, foaming agent 1-2 parts, additive 1-2
Part.
Further, the macroreticular resin is GMA-EGDMA macroreticular resins, and GMA-MBAA macroreticular resins or GMA-DVB are big
One kind in the resin of hole.
Further, the adhesive is one kind in polyvinyl acetate, polyvinyl alcohol or butadiene-styrene rubber.
Further, the foaming agent includes calcium carbonate, magnesium carbonate, sodium acid carbonate.
Further, the additive is water reducer.
The advantage of the invention is that：The pervious concrete of the present invention is doped with macroreticular resin, special due to macroreticular resin
Structure, so it has unusual specific surface area, it can be combined together with aggregate, adhesive etc. with larger contact area,
Additionally, due to the presence in macroreticular resin space so that the permeability of concrete is greatly improved, and its water penetration is improved so having reached
Effect.The pervious concrete has good compression strength and coefficient of permeability, disclosure satisfy that it is various have for concrete it is permeable
It is required that requirement of engineering, be advantageous to maintaining ecological balance and realize sustainable development.
Coal dust in original formula is substituted using lime stone matter stone flour, the dependence to coal dust is greatly alleviated, reduces
The production cost of concrete, improves economic benefit.
