By adoption of the concrete multifunctional corrosion remover and the preparation method, the defect of the prior art is overcome, the freeze-thaw damage and wetting and drying alternation damage to the concretes can be avoided, the sulphate resisting cements which are high in price and severe in pollution to production can be replaced, and the concrete multifunctional corrosion remover is completed in function and capable of resisting the destroy of soils and complicated underground water to the concretes, and can be adjusted in performance according to using requirements.
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 there is the superperformances such as anti-salt ion erosion, freeze-thaw-circulation destruction and high impermeabilisation.Particularly suitable had not only required anticorrosion but also had required impervious engineering concrete structure.Mix this product and can also make concrete shrinkage value reduce, be convenient to mass concrete construction.Concrete antiseptic agent application is 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 add appropriate sanitas (replacing part of cement with flyash or breeze) in ordinary Portland cement, 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 exceedes 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.The Steel Concrete that adopts concrete antiseptic agent to produce has corrosion-resistant, freeze-thaw-, high strength, impermeable, shrink the excellent properties little, water-reducing rate is high.
The sanitas product function such as sulfate resistance sanitas, rust inhibitor of selling is on the market single, use range limitation, during for anti-corrosion concrete, must use with the admixture of sulphate resisting portland cement, raising weather resistance etc. simultaneously, and can not be used for the environment of alternation of wetting and drying, high and low temperature alternative, Xinjiang region complex geologic conditions, high, the alternation of wetting and drying of salt content in soil, underground water, these product results of use of high and low temperature alternative are poor.
Thereby, existing concrete antiseptic agent technology cannot 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, cannot resist soil, underground water complexity to concrete destruction.
Prior art performance is very single, cannot according to requirements carry out performance adjustment.
Summary of the invention
The technical issues that need to address of the present invention are just to overcome the defect of prior art, a kind of concrete multifunction sanitas and preparation method thereof is provided, it has overcome the defect 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 resist soil, underground water complexity to concrete destruction, and according to requirements carries out 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: 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;
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;
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 Sunmorl N 60Ss, 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 are fully mixed, D component is configured to 1% solution to be evenly sprayed onto in above mixture, after oven dry, grinding to fineness reaches 400 orders, 40kg/ bag packing.
In the present invention, the main component of A component: silicon-dioxide, aluminum oxide, calcium hydroxide, the hydrate that can generate with vitriol, carbonate, calcium hydroxide generation chemical reaction stable performance has consumed harmful salinity in course of hardening, has stoped the destruction of salinity to concrete structure.The interpolation of calcium hydroxide can be adjusted the pH value after concrete hydrating, stops decomposition, the destruction of the hydrolysis product of cement causing due to the consumption of calcium hydroxide, is 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 concrete and can form uniform micro-bubble, discharges concrete and is subject to freeze thawing to produce volume stress, improves concrete freezing and thawing performance.
