Description
Technical field
The present invention relates to a kind of concrete multifunction sanitas and preparation method thereof.
Background technology
Concrete antiseptic agent is a kind of completely new product that a new generation prevents steel reinforced concrete erosion, it has broken through the etch-proof traditional idea of Steel Concrete, start use admixture rot-resistant novel method, fundamentally solved many deficiencies and the limitation of traditional anti-corrosion method.Use sulfate corrosion-resistance preservative for concrete can make concrete have the superperformances such as anti-salt ion erosion, freeze-thaw-circulation destruction and high impermeabilisation.Particularly suitable not only requires anticorrosion but also require impervious engineering to concrete structure.Mix this product the concrete shrinkage value is reduced, be convenient to mass concrete construction.Concrete antiseptic agent is used easy, does not need special construction technique.This anti-corrosion method has also fully utilized industrial waste---flyash simultaneously, has the meaning of environmental protection.
By an amount of sanitas of adding in ordinary Portland cement (replacing part of cement with flyash or breeze), and make a kind of new gelling material, product meets the building material industry standard JC/T1011-2006 of People's Republic of China (PRC) indices.The sulfate resistance ability of this gelling material has surpassed the AS advanced sulfur-resistant acid salt cement level of regulation in " railway concrete and stonework standard " appendix 13.Concrete endurance quality and workability are improved a lot.Adopt the Steel Concrete of concrete antiseptic agent production to have corrosion-resistant, freeze-thaw-, high strength, the excellent properties that impermeable, contraction is little, water-reducing rate is high.
The sanitas product functions such as the sulfate resistance sanitas of selling on the market, rust inhibitor are single, the use range limitation, must use simultaneously with the admixture of sulphate resisting portland cement, raising weather resistance etc. when being used for anti-corrosion concrete, and can not be used for the environment of alternation of wetting and drying, high and low temperature alternative, the Xinjiang region complex geologic conditions, high, the alternation of wetting and drying of salt content in soil, the underground water, these product results of use of high and low temperature alternative are poor.
Thereby, existing concrete antiseptic agent technology can't be tackled freeze-thaw damage, alternation of wetting and drying to concrete destruction, and can not substitute expensive, produce with serious pollution sulphate resisting portland cement, and function singleness can't be resisted soil, underground water complexity to concrete destruction.
The prior art performance is very single, can't according to requirements carry out the performance adjustment.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, a kind of concrete multifunction sanitas and preparation method thereof is provided, it has overcome the defective of prior art, can tackle freeze-thaw damage, alternation of wetting and drying to concrete destruction, and can substitute expensive, produce with serious pollution sulphate resisting portland cement, complete function can be resisted soil, underground water complexity to concrete destruction, and according to requirements carries out the performance adjustment.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of concrete multifunction sanitas, described sanitas is mixed by following parts by weight of component: the A component: 30 parts of opposing vitriol, carbonate material; B component: 20 parts of opposing villaumite materials, C component: 10 parts of anti-crack and anti-seepage materials, D component: 3 parts of freeze-thaw-materials, E component: 10 parts of the materials of gaining in strength, F component: improve 17 parts of concrete flowability materials, G component: improve 10 parts of density materials.
The weight part proportioning of A component is: 50 parts of aluminum oxide, 30 parts of silicon-dioxide, 20 parts of calcium hydroxides;
The B component is calcium nitrite;
The weight part proportioning of C component is: 10 parts of polypropylene fibres, 0.5 part of organic swelling agent, 89.5 parts of water glass;
The D component is colophonium pyrolytic polymer;
The weight part proportioning of E component is: 75 parts of nitrocalcite, 25 parts of calcium oxide
The weight part proportioning of F component is: 92 parts of naphthene sulfonic acid calcium, 4 parts of glucose sodium saccharates, 4 parts of citric acids;
The weight part proportioning of G component is: 65 parts of SILICA FUME, 35 parts of super finely ground slags.
The present invention provides a kind of preparation method of described concrete multifunction sanitas simultaneously, after A component, B component, C component, E component, F component and G component fully mixed, the D set of dispense is set to 1% solution evenly to be sprayed onto in the above mixture, after the oven dry, grinding to fineness reaches 400 orders, 40kg/ bag packing.
Among the present invention, the main component of A component: silicon-dioxide, aluminum oxide, calcium hydroxide, can generate with vitriol, carbonate, calcium hydroxide generation chemical reaction the hydrate of stable performance, in course of hardening, consume harmful salinity, stop the destruction of salinity to concrete structure.The interpolation of calcium hydroxide can be adjusted the pH value behind the concrete hydrating, stops because decomposition, the destruction of the hydrolysis product of cement that the consumption of calcium hydroxide causes are the reactant of vitriol and silicon-dioxide, aluminum oxide generation chemical reaction simultaneously.
The main component of B component is calcium nitrite, and calcium nitrite again rebar surface forms passive film, stops the corrosion of reinforcing bar, and calcium nitrite can improve concrete intensity simultaneously.
The main component polypropylene fibre of C component, organic swelling agent improve concrete anticracking, anti-permeability performance.
It is colophonium pyrolytic polymer that the group of D component is wanted composition, adds in the concrete and can form uniform micro-bubble, discharges concrete and is subjected to freeze thawing to produce volume stress, improves concrete freezing and thawing performance.
The main component of E component is nitrocalcite, calcium oxide, and the activity of excited cementing material improves concrete strength;
The main component of F component is naphthalenesulfonate formaldehyde condensation compound, methylol carboxylate salt, improves concrete flowability by forming electric double layer on the gelling material surface.
