Abstract
The present invention relates to concrete pavement construction method, specifically a kind of method for improving coastal area concrete road surface alkali resistance.This method is：After Common Concrete Pavement pouring molding, dried under its surface spraying long-chain alkyl-silicone oil or long-chain alkyl-silicone oil emulsion, natural conditions, concrete surface layer is turned into the corrosion-resistant coating of low water absorption, low chlorine ion permeability and highly-breathable.After the concrete road surface spraying chain alkyl silicon or long-chain alkyl-silicone oil emulsion of the present invention, concrete roadway surface can form the organosilicon material layer of one layer of low surface tension, machine silicon material layer can play good anti-corrosion and waterproof, alkaline-resisting, impervious effect, so as to improve the service life of concrete road surface.
Description
Technical field
The present invention relates to concrete pavement construction method, specifically a kind of raising coastal area concrete road surface alkali resistance
Method.
Background technology
Alkali content is higher in the environment of coastal area, the salt dissolved in carbonization, water caused by acidic gas in air, especially
It is chlorion, catastrophic corrosion can be caused to concrete, environmental factor also can be to concrete corrosion, also can be to wherein reinforcing bar
There is the corrosivity of strength, how to improve coastal area concrete road surface alkali resistance turns into the problem of coastal cities municipal works.Profit
Good waterproof, protection against the tide, alkali resistant effect can be played with the low surface tension of organosilicon material, so as to improve the use longevity of concrete
Life.
The content of the invention
A kind of present invention seek to address that the problem of coastal area concrete alkali resistance, there is provided low table using organosilicon material
Face tension force reaches the method for improving coastal area concrete road surface alkali resistance of waterproof, protection against the tide, alkali resistant effect.
The present invention solves the technical scheme that its technical problem uses：
A kind of method for improving coastal area concrete road surface alkali resistance, after Common Concrete Pavement pouring molding, in concrete
Road surface sprays long-chain alkyl-silicone oil or long-chain alkyl-silicone oil emulsion, is dried under natural conditions, makes concrete road surface top layer shape
Into the corrosion-resistant coating of one layer of low water absorption, low chlorine ion permeability and highly-breathable.
The principle of the invention is：Because remaining part Si -- H bond in long-chain alkyl-silicone oil, thus fabric or filler are hated
Water-based and concrete alkali resistance effect is especially good.α benzenes surface tension 32.5,150 DEG C of containing hydrogen silicone oil flash-point, surface
Tension force 20, it is the production after hydrogen bond in containing hydrogen silicone oil is substituted by chain alkyl by long-chain alkyl-silicone oil made of Si―H addition reaction
Thing, there is good hydrophobicity and soil resistance.
Based on this, using the present invention of above-mentioned technical proposal, its advantage is：
After concrete road surface sprays chain alkyl silicon or long-chain alkyl-silicone oil emulsion, concrete roadway surface can form one layer of low table
The organosilicon material layer of face tension force, machine silicon material layer can play good anti-corrosion and waterproof, alkaline-resisting, impervious effect, so as to improve
The service life of concrete road surface.
Preferably, the further technical scheme of the present invention is：After described Common Concrete Pavement pouring molding, it is
After concrete road surface pouring molding completes maintenance slot.So at slot, the formation of the waterproof layer can effectively keep out water
Into among the basic unit below road surface and roadbed, the stability of road can be further improved.
Embodiment
The present invention is described in detail with reference to embodiments.
A kind of method for improving coastal area concrete road surface alkali resistance, is carried out in the steps below：
After concrete road surface pouring molding completes maintenance slot, one layer of long-chain alkyl-silicone oil or long alkane are sprayed in concrete road surface
Base silicone oil emulsion, one layer of waterproof, corrosion-resistant coating are formed after natural drying, especially at slot, the formation of the waterproof layer can
Water is effectively kept out to enter among the basic unit below road surface and roadbed.
Concrete road surface top layer long-chain alkyl-silicone oil or its Emulsion Spraying, dipping, make concrete surface layer have low water suction
The anticorrosive property of rate, low chlorine ion permeability and highly-breathable, reach waterproof, alkaline-resisting effect.
The above described is only a preferred embodiment of the present invention, not the structure of the present invention is made any formal
Limitation.Any simple modification, equivalent change and modification that every technical spirit according to the present invention is made to above example, still
Belong to the scope of technical solution of the present invention.
Claims (2)
