Abstract
The invention relates to a concrete preservative which comprises a dense component and a corrosion-resistant component, wherein the dense component is silicate mineral, and the using amount of the silicate mineral is 0.5-1.0% of the mass of a cementing material in concrete; the corrosion-resistant component is over-burnt 2BaO SiO2And eleostearic acid, 2 BaO. SiO2The using amount of the eleostearic acid is 7.0-7.5% of the mass of the cementing material in the concrete, and the using amount of the eleostearic acid is 0.02-0.04% of the mass of the cementing material in the concrete. The over-sintered 2BaO SiO2Grinding together with eleostearic acid in a ball mill until the specific surface area is not less than 300m2And/kg, then adding the silicate mineral, and uniformly stirring. The corrosion inhibitor is effective in improving the sulfate corrosion resistance of concrete when incorporated into concrete, and thus the cost is much lower than when sulfate-resistant portland cement is used.
Description
Technical field
The present invention relates to building material field, specifically a kind of for preventing in concrete that concrete from suffering the product of containing sulfate dielectric corrosion.
Background technology
The concrete the most frequently used effective means of preparation sulfate resistance dielectric corrosion is to adopt at present:
Sulfate resistance portland cement: the content that the total amount that in cement, the content of C3A is not more than 5.0%, C3A+C4AF is not more than 22%, C3S is not more than 50%.
The sulfate resistance portland cement that contains mineral admixture: in grog, the content of C3A is not more than 5.0%, the permission content of the active mineral admixture in cement component is below 10%.
Sulfate resistance slag portland cement: adopt the content of C3A to be not more than 8.0% grog and Al2O3 content and be also not more than 8.0% slag and make.
Adopt sulfuric-resisting salt portland cement concrete batching, method simple possible, and anti-sulphates corrosive ability is more stable.
But sulfuric-resisting salt portland cement industrial scale is less at present, output is lower, far can not meet the needs of Practical Project, and the price of cement is relatively high, makes the cost of engineering also higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide the better concrete antiseptic agent of a kind of preservative effect.
For solving the problems of the technologies described above, concrete antiseptic agent of the present invention, is comprised of closely knit component and antiseptic ingredient, wherein:
-closely knit component is silicate minerals, usage quantity be gelling material in concrete quality 0.5%～1.0%;
-anti-corrosion composition is the 2BaOSiO of burning
2and eleostearic acid, 2BaOSiO
2usage quantity is the quality 7.0%～7.5% of gelling material in concrete, the usage quantity of eleostearic acid be gelling material in concrete quality 0.02%～0.04%.
In above-mentioned composition,
Described 2BaOSiO
2to specific surface area, be not less than 300m with eleostearic acid intergrinding in ball mill
2/ kg, then adds closely knit component, stirs.
The molecular composition of described silicate minerals is (1/2Ca, Na)

4nH
2o.
Preferably, the usage quantity of silicate minerals be gelling material in concrete quality 0.7%, 2BaOSiO
2and eleostearic acid, 2BaOSiO
2usage quantity is the quality 7.0% of gelling material in concrete, the usage quantity of eleostearic acid be gelling material in concrete quality 0.03%.
A kind of method of preparing concrete antiseptic agent of the present invention comprises the following steps: the 2BaOSiO of burning
2to specific surface area, be not less than 300m with eleostearic acid intergrinding in ball mill
2/ kg, then adds silicate minerals, stirs.

2three layers of ore of the dioctahedron crystalline structure of O have intracrystalline and hold swollen ability, it is nano level gel that chance water can be dispersed into size of particles gradually, the pore of fill concrete inside, increase considerably concrete degree of compactness, thereby stop or slow down aggressive sulphuric salt medium, be penetrated into inside concrete, avoid damaging concrete internal structure.Eleostearic acid itself just has anti-sulphates corrosive ability, and can also delay 2BaOSiO
2hydration rate, to avoid the gypsum that cement is mixed to react with BaO, affect normally condensing of cement at home and abroad; BaO with ooze the SO in people's concrete
4 2-reaction, generating is almost insoluble compound---BaSO
4, make water mudrock structure finer and close, also avoided generating the reaction of ettringite simultaneously.
This sanitas mixes the ability that can effectively improve concrete anti-sulphates corrosive in concrete, and the cost increasing is thus than adopting low many of sulfuric-resisting salt portland cement.
