Abstract
The invention provides a cement alkali resistance additive with alkali resistance, enhancement, weather ability and carbonization resistance, and a preparation method thereof. The cement alkali resistance additive is used through the steps of adding 0.5-0.8 parts of the cement alkali resistance additive to 100 parts (by weight) of a cement-based material and through uniformly stirring. The cement alkali resistance additive overcomes the building industry problem of easy saltpetering of cement materials, improves the strength of cement products, effectively improves the weather ability of the cement products and increases the carbonization resistance of the cement products.
Description
Technical field
The present invention relates to a kind of cement additire, specifically a kind of have face upward the cement accumulation of salt in the surface soil processed, improve strength of cement, improve the cement of cement weather resistance and face upward alkali additive and preparation method.
Background technology
Come out 180 for many years from Britain's portland cement, it, as a kind of important gelling material, is widely used in the engineerings such as civil construction, water conservancy, national defence.Silicate cement main component is calcium oxide, silicon oxide, aluminum oxide and ferric oxide, tricalcium silicate, Dicalcium Phosphate (Feed Grade), tricalcium aluminate, tetracalcium aluminoferrite is become by high-temperature calcination, also have some free calcium oxide, cement tricalcium silicate, Dicalcium Phosphate (Feed Grade) and water reaction when carrying out hydration reaction generates calcium hydroxide, and the calcium oxide calcining the reasons such as non-chemical combination free also generates calcium hydroxide after hardening of cement.In cement containing the moisture of calcium hydroxide by the pore of material to external migration, and carbon dioxide reaction dehydration precipitation forms the accumulation of salt in the surface soil (Ca (OH) 2+CO2=CaCO3 ↓+H2O).The cement accumulation of salt in the surface soil is the technical barrier that construction industry is difficult to capture all the time, and it is attractive in appearance that the accumulation of salt in the surface soil can affect buildings, delamination easily occurs and makes finishing failure, even can cause textural anomaly dilatation fissure.The mould that moist position is multiplied because of the cement accumulation of salt in the surface soil easily causes tetter and respiratory tract disease.So, invent and a kind ofly face upward the cement accumulation of salt in the surface soil processed, improve strength of cement, improve the cement of cement products weather resistance and face upward alkali additive and preparation method is very necessary.
Summary of the invention
The object of this invention is to provide and a kind ofly face upward the cement accumulation of salt in the surface soil processed, improve strength of cement, improve the cement of cement weather resistance and face upward alkali additive and preparation method.
The present invention is realized by following technical scheme, a kind of cement is faced upward alkali additive and is made up of by weight proportion following raw materials according, sodium polyphosphate 6 ~ 12%, ferrous sulfate 3 ~ 9%, Sodium Nitrite 1 ~ 6%, Sodium dodecylbenzene sulfonate 4 ~ 10%, potassium aluminium sulfate 15 ~ 21%, water glass 22 ~ 28%, water reducer 14 ~ 20%, organosilicon 12 ~ 18%.
Be dry mixed that whipping device carries out mixing, stirring obtains described cement and face upward alkali additive with vertical after being weighed in proportion by above-mentioned starting material.Mix is joined in cement-based material evenly according to the ratio of 0.5 ~ 0.8% of cement-based material gross weight during use.
Additive of the present invention and hydrated cementitious calcium hydroxide reaction generate silicic acid gel material, shutoff cement material pore, face upward the accumulation of salt in the surface soil phenomenon having made cement products, also improve the intensity of cement products, improve the weather resistance of cement products, effectively reduce the carbonation depth of cement products.

Embodiment 2
Alkali additive faced upward by a kind of cement, is made up of by weight proportion, sodium polyphosphate 6%, ferrous sulfate 8%, Sodium Nitrite 1%, Sodium dodecylbenzene sulfonate 10%, potassium aluminium sulfate 15%, water glass 28%, water reducer 14%, organosilicon 18% following raw materials according.
Embodiment 3
Alkali additive faced upward by a kind of cement, is made up of by weight proportion, sodium polyphosphate 12%, ferrous sulfate 3%, Sodium Nitrite 6%, Sodium dodecylbenzene sulfonate 4%, potassium aluminium sulfate 21%, water glass 23%, water reducer 13%, organosilicon 18% following raw materials according.
Above-mentioned cement is faced upward alkali additive to be joined in cement-based material, 100 parts of (weight) cement-based materials add 0.5 ~ 0.8 part of cement and face upward alkali additive, after adopting the cement of the present embodiment to face upward alkali additive, face upward alkali effective, improve cement products intensity, effectively improve the weather resistance of cement products, reduce the carbonation depth of cement products.There are very high promotion and application be worth.
Claims (1)
