Abstract
A surface-reinforcing sealant for cement concrete is prepared from magnesium fluorosilicate, siloxane emulsion, aluminium sulfate and water through proportional mixing. Its advantage is high effect o increase surface strength of concrete, prevent rusting of steel, and improve antiwear and water-proof performance.
Description
Technical field
The present invention relates to a kind of cement concrete surface-reinforcing sealant, can improve the intensity of concrete surface, anti-steel bar corrosion, anti-carbonization, wear resistance and waterproof ability.
Technical background
Structure building is under arms in the process, be subjected to physics, chemistry, the biological action of surrounding environment, as microbial attack, magnesium salts, acid rain, carbonic acid gas, chloride erosion etc., some composition in the concrete reacts, dissolves, expands, thereby causes deterioration, the destruction of concrete structure.
Comprehensive concrete deterioration mechanism, the major cause of concrete deterioration process (physics, chemistry and biological) and reinforcing bar or prestressed reinforced concrete generation deterioration has freeze-thaw cycle, alkali-aggregate reaction, sulphate attack, shrinkage cracking and steel bar corrosion etc.For its any deterioration, it is all relevant with water with the rimose reason to expand, and water also is that corrosive medium (as villaumite, vitriol etc.) migration enters the carrier in the concrete simultaneously.Water is the transmission medium that destroys material, is again to destroy the prerequisite of generation and the basis of many failure mechanisms and modelling.The various degradation mechanism of analysis-by-synthesis concrete structure as can be known, nearly all chemistry and physical process that influences concrete structure durability all relates to two main influence factors, i.e. water and the migration in concrete pore and crack thereof.Therefore, strengthen concrete is carried out effective sfgd. to improve the density of concrete structure, reduce water permeate,, guarantee that the concrete security has the realistic meaning of weight improving concrete work-ing life.It is also very urgent to develop a kind of surface-reinforcing sealant that can improve concrete surface intensity, degree of compactness and water-repellancy.
Summary of the invention
The object of the present invention is to provide a kind of cement concrete surface of the intensity of concrete surface, anti-steel bar corrosion, anti-carbonization and waterproof ability that can improve with strengthening sealing agent.
The cement concrete surface that the present invention proposes is made up of magnesium silicofluoride, silicone emulsion, Tai-Ace S 150, water with strengthening sealing agent, and each weight percentages of components is:
Magnesium silicofluoride 100
Silicone emulsion (solid content) 12-200
Tai-Ace S 150 0-160
Water 100-700
The preferable part by weight of each component is:
Magnesium silicofluoride 100
Silicone emulsion (solid content) 40-60
Tai-Ace S 150 15-30
Water 200-250.
The present invention is a kind of cement concrete use silicates compound surface treatment agent.It had both had enhancing, densification preferably, and the waterproof sealing effect is arranged again.
When the present invention is applied in cement concrete surface, after magnesium silicofluoride can infiltrate in hardened cement concrete surface hole and the microfracture, react with hydrated cementitious product calcium hydroxide, generate silica dioxide gel and fluorochemical, fill concrete surface and inner capillary-size pore, reduce the primary defective of cement concrete surface, improve the pore structure on top layer, the raising of cement concrete surface intensity, wear resistance ratio are enhanced about more than once before being untreated.Simultaneously the siloxanes of low polymerization degree also can be penetrated into inside concrete and hydrolysis or form hydrophobic film or product with the reaction of hydrated cementitious product in the component, has hydrophobic, waterproof effect preferably.
The present invention is a kind of white emulsion; can produce chemical reaction, water miscible plugging agent; it can infiltrate concrete, heavy concrete brick, sand-cement slurry, gypsum, wash in the mixture of stone, terrazzo and any sand, stone, cement, and permanent protection and enhancement are provided.Can be widely used in the enhancing and the sealing of concrete surfaces such as bridge, tunnel, motorway, buildings.
The present invention prepares easy control, at first a certain amount of magnesium silicofluoride is dissolved in the water, and the silicone emulsion with the regulation ratio mixes then, and the white liquid that obtains even matter gets final product.
Distinct advantages of the present invention has:
(1) have higher strengthening the property, because formula material composition of the present invention can be produced product with cement reaction, combine closely together, increase density, intensity and the hardness of concrete surface, this hardened process can prevent that the cement flooring is closely knit inadequately and the destruction that produces.
(2) have preferably fill, densification, the present invention deeply infiltrates into concrete surface 5mm, produces the chemical reaction in a kind of pinning inside concrete space, provides far-reaching permanent shutoff to the concrete surface of various forms.Form a strong imperforate entity list surface layer;
(3) have waterproof, sealing function preferably, siloxanes can be penetrated into inside concrete and hydrolysis or form hydrophobic film or product with the reaction of hydrated cementitious product in the present invention prescription, has hydrophobic, waterproof effect preferably;
(4) have higher anti-environmental attack ability, especially can improve anti-carbonization, anti-steel bar corrosion and viscosifying power.Owing to eliminate the concrete salt and the impurity of surperficial unfavorable combination, and the surface enhancing makes the perviousness of concrete carbonic acid gas reduce greatly with closely knit;
(5) have ventilation property preferably, the sealing agent after the present invention handles both can stop the infiltration of water molecules, can see through the water vapour in the concrete again and film like the skin and appear.The moisture that is enclosed in the concrete can in time be appeared;
(6) long-lasting effect: need only use the present invention once, cement concrete surface just forever has good enhancing, high-durability, waterproof and stopping property.
