Abstract
The invention discloses an anticorrosive anti-erosion additive for high-belite cement, which is prepared from the following components in weight percentage: 15-22 percent of naphthalene sulfonated formaldehyde condensate, 5-15 percent of tertiary butyl benzoic acid, 2-5 percent of ethyl silicate, 15-25 percent of slag powder, 15-25 percent of coal ash and the balance of water. By adding the anticorrosive anti-erosion additive for the high-belite cement to the high-belite cement, the anticorrosive anti-erosion ability of concrete prepared from the high-belite cement can be enhanced. Meanwhile, the anticorrosive anti-erosion additive for the high-belite cement has a water-reducing function and an air-entraining function and is capable of prolonging the service life of the concrete prepared from the high-belite cement and broadening the application range of the high-belite cement.
Description
Technical field
The present invention relates to a kind of additives for building materials, especially relate to the anticorrosion anti-erosion additive of a kind of high belite cement.
Background technology
At present, the cement that anhydrite is processed exists not enough aspect anticorrosion anti-erosion, can not satisfy the needs of some special dimension, such as the plant and equipment of gas washing in SA production enterprise, so often need be to wherein adding some material to strengthen its anticorrosion erosion-resisting characteristics.
What in hydraulic structure such as impact-resisting wear-resisting cavitation prevention concrete, road abrasion-proof concrete, terrace abrasion-proof concrete etc., use all is silica flour class impact-resisting wear-resisting additive, and it is to reach anticorrosion erosion-resistant effect with silica flour instead of part cement with the enhancing concrete crushing strength, and this is for concrete; Under the situation of equal hydration heat, compare with common cement concrete, do not have tangible reinforced effects; Because the effect of silica flour has reduced cement consumption, concrete ultimate compression strength has improved; Anticorrosion erosion-resisting characteristics has also improved; But the cement that it is processed for anhydrite, it improves very limited, can not reach satisfied effect.
The firing temperature of high belite cement is low; The quantity discharged of the carbonic acid gas that in sintering process, produces, sulfurous gas etc. is low, and energy consumption is low, and environmental pollution is few; Production cost is low; And its intensity, weather resistance are all good than common cement, but high belite cement aspect anticorrosion, anti-erosion and Portland cement almost as broad as long, this directly causes it can not be applied to occasion anticorrosion, that the anti-erosion aspect has higher requirements.
Summary of the invention
The technical problem that the present invention will solve is, overcomes the deficiency of prior art, and a kind of anticorrosion anti-erosion additive of high belite cement that can improve the anticorrosion erosion-resisting characteristics of high belite cement is provided.
The present invention solve the technical problem the technical scheme that is adopted; The anticorrosion anti-erosion additive of a kind of high belite cement, formulated by following components in weight percentage: naphthalenesulfonate formaldehyde condensation compound 15-22%, the special fourth 5-15% of phenylformic acid; Ethyl silicate 2-5%; Slag powders 15-25%, coal ash powder 15-25%, surplus is a water.
Preferred weight percent is: naphthalenesulfonate formaldehyde condensation compound 20%, the special fourth 10% of phenylformic acid, ethyl silicate 3%, slag powders 20%, coal ash powder 20%, water 27%.
The preferred naphthalenesulfonic acid-formaldehyde condensate of said naphthalenesulfonate formaldehyde condensation compound.
The preparation method: each the solid particulate matter component in will filling a prescription adds in the liquid material in the prescription, grinds, and processes slurry.
Method of use: additive of the present invention is joined in the cement clinker, and addition is the 0.5-5% of cement clinker weight, is preferably 2%.
The anticorrosion anti-erosion additive of the present invention's high belite cement; Add among the high belite cement, can strengthen the concrete anticorrosion corrosion resistance processed with this cement, have diminishing, air-entraining function simultaneously; Be applicable to various places; Such as maritime works's engineering, deleterious solonchak medium engineering and the engineering that needs long-term safety to use, can prolong the concrete work-ing life that high belite cement is processed, enlarge the range of application of high belite cement.
