Description
Technical field
The present invention relates to building material field, specifically a kind of for preventing concrete from suffering the product of containing sulfate dielectric corrosion in concrete.
Background technology
The preparation concrete the most frequently used effective method of sulfate resistance dielectric corrosion is to adopt at present:
Sulfate resistance Portland cement: in cement, the content of C3A is not more than 5.0%, the total amount of C3A+C4AF is not more than 22%, and the content of C3S is not more than 50%.
Sulfate resistance Portland cement containing 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 be not more than 8.0% grog and Al2O3 content be also not more than the slag of 8.0% and make.
Adopt sulfuric-resisting salt Portland cement concrete batching, method simple possible, and anti-sulphates corrosive ability is more stable.
But, current sulfuric-resisting salt Portland cement production scale is less, and yield is relatively low, far from the needs meeting Practical Project, and, the price of cement is of a relatively high, and the cost making engineering is also higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of better concrete antiseptic agent of antiseptic effect.
For solving above-mentioned technical problem, the concrete antiseptic agent of the present invention, it is made up of closely knit component and antiseptic ingredient, wherein:
-closely knit component is silicate mineral, and making consumption is in concrete the 0.5%��1.0% of the quality of Binder Materials;
-anti-corrosion composition is the 2BaO SiO of burning2And eleostearic acid, 2BaO SiO2The quality 7.0%��7.5% making consumption be Binder Materials in concrete, the consumption that makes of eleostearic acid is in concrete the 0.02%��0.04% of the quality of Binder Materials.
In above-mentioned composition,
Described 2BaO SiO2It is not less than 300m to specific surface area with eleostearic acid intergrinding in ball mill2/ kg, is subsequently adding closely knit component, stirs.
The molecular composition of described silicate mineral is (1/2Ca, Na)0.7(Al, Mg, Fe)4(Si, Al)8O20(OH)4��nH2O��
Preferably, the consumption that makes of silicate mineral is in concrete the 0.7% of the quality of Binder Materials, 2BaO SiO2And eleostearic acid, 2BaO SiO2The quality 7.0% making consumption be Binder Materials in concrete, the consumption that makes of eleostearic acid is in concrete the 0.03% of the quality of Binder Materials.
The method of the concrete antiseptic agent of a kind of present invention of preparation comprises the following steps: the 2BaO SiO of burning2It is not less than 300m to specific surface area with eleostearic acid intergrinding in ball mill2/ kg, is subsequently adding silicate mineral, stirs.
The molecular composition of described silicate mineral is (1/2Ca, Na)0.7(Al, Mg, Fe)4(Si, Al)8O20(OH)4��nH2O��
Described 2BaO SiO2, at the temperature lower calcination 30 minutes of 1200 DEG C-1300 DEG C.
Molecular composition is (1/2Ca, Na)0.7(Al, Mg, Fe)4(Si, Al)8O20(OH)4��nH2The three layers Ore of the dioctahedron crystal structure of O has intracrystalline and holds swollen ability, it is nano level gel that chance water can be dispersed into particle size gradually, pore within fill concrete, increase considerably concrete degree of compaction, inside concrete is penetrated into, it is to avoid damage concrete internal structure thus stoping or slowing down aggressive sulphuric salt medium. Eleostearic acid inherently has anti-sulphates corrosive ability, and can also delay 2BaO SiO2Hydration rate, to avoid the Gypsum Fibrosum mixed of cement China and foreign countries react with BaO, affect normally condensing of cement; BaO and the SO oozed in people's concrete4 2-Reaction, generating is almost insoluble compound BaSO4, make water mudrock structure finer and close, it also avoid the reaction generating entringite simultaneously.
This preservative mixes the ability that can be effectively improved concrete anti-sulphates corrosive in concrete, and the cost thus increased ratio adopts low many of sulfuric-resisting salt Portland cement.
