Abstract
The present invention relates to the method for concrete alkali resistance, specifically a kind of method for improving coastal area concrete alkali resistance.This method is：When preparing concrete, it is directly appended to using long-chain alkyl-silicone oil emulsion as concrete additive in concrete, after concreting shaping, concrete, which has, prevents in water salt and chlorion to the corrosive nature of reinforcing bar.The basis mechanism of the present invention：Part Si H keys are remained in long-chain alkyl-silicone oil, it is especially good to the alkali resistance effect of the hydrophobicity and concrete of fabric or filler.Based on this, long-chain alkyl-silicone oil improves impermeability, the Saline alkali tolerance of concrete, waterproof, corrosion-resisting function can be played to reinforcing bar as concrete additive.
Description
Technical field
The present invention relates to the method for concrete alkali resistance, specifically a kind of side for improving coastal area concrete 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 alkali resistance turns into the problem of coastal cities municipal works.Using having
The low surface tension of machine silicon materials can play good waterproof, protection against the tide, alkali resistant effect, so as to improve the service life of concrete.
The content of the invention
Present invention seek to address that the problem of coastal area concrete alkali resistance, there is provided one kind improves coastal area concrete road
The method of face alkali resistance, the characteristics of it takes full advantage of organosilicon material impervious, Saline alkali tolerance.
The present invention solves the technical scheme that its technical problem uses：
A kind of method for improving coastal area concrete alkali resistance, this method are：When preparing concrete, long-chain alkyl-silicone oil is made
It is directly appended to for concrete additive in concrete, after concreting shaping, concrete, which has, prevents salt and chlorine in water
The corrosive nature of ion pair reinforcing bar.
The principle of the invention is：Part Si -- H bond is remained in long-chain alkyl-silicone oil, hydrophobicity to fabric or filler and
The alkali resistance effect of concrete is especially good.Based on this, using the present invention of above-mentioned technical proposal, its advantage is：
Long-chain alkyl-silicone oil improves impermeability, the Saline alkali tolerance of concrete, reinforcing bar can be played as concrete additive
Waterproof, corrosion-resisting function.
Preferably, the further technology of the present invention puts case is：
Long-chain alkyl-silicone oil emulsion is added in concrete mix as a kind of concrete additive when preparing concrete and is made
The concrete of different model；The additional proportion of cement, sand, stone, long-chain alkyl-silicone oil emulsion and water is adjusted, is prepared different strong
The concrete of degree.
The concrete of the varying strength includes C15 concrete, and its feed ratio is：Cement 330kg, sand 619kg, stone
Sub- 1200kg, long-chain alkyl-silicone oil emulsion 60kg, water 100kg, C15 slumps made of stirring are 20mm.
Embodiment
The present invention is described in detail with reference to embodiments.
A kind of method for improving coastal area concrete alkali resistance, is carried out in the steps below：
When preparing concrete, long-chain alkyl-silicone oil emulsion is added in concrete mix as a kind of concrete additive and is made
C15 concrete, C15 concrete feed ratios are：Cement 330kg, sand 619kg, stone 1200kg, long-chain alkyl-silicone oil emulsion
60kg, water 100kg, concrete strength made of stirring is qualified, slump 20mm, meets concrete standard.
Concrete manufactured in the present embodiment, available for the different fields such as road construction, bridge, building construction, reinforcing steel bar laying
Finish and pour concrete of the present invention, because the long-chain alkyl-silicone oil added in concrete has the physiological inertia of organosilicon product in itself
And Si -- H bond can play a protective role to reinforcing bar to the alkali resistance of the hydrophobicity and concrete of fabric or filler, prevent steel
Muscle gets rusty, so as to extend the service life of building.
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.
