Abstract
The invention relates to the technical field of anti-freezing agents, particularly to a concrete anti-freezing agent. The concrete anti-freezing agent is formed by the following raw materials of, by weight, 15 to 25 parts of poly carboxylic acid water reducing agents, 5 to 10 parts of sodium lignin sulfonate, 5 to 10 parts of alkyl glycoside, 0.3 to 0.8 part of tea saponin, 3 to 6 parts of sodium gluconate, 0.1 to 0.5 parts of sodium dodecyl benzene sulfonate, 6 to 12 parts of calcium formate and 30 to 40 parts of water through preparation. According to the concrete anti-freezing agent, the adaptability to concrete is good, the quality is stable, the product is environmentally-friendly, various engineering requirements can be met, and the concrete can be maintained not to freeze at minus 30 DEG C to minus 20 DEG C.
Description
Technical field
The present invention relates to frostproofer technical field, particularly a kind of concrete antifreezer.
Background technology
In northern China winter construction, in order to ensure that the quality of engineering prevents concrete generation freeze injury, mainly take two kinds of safeguard procedures, one is adopt to cover or go along with sb. to guard him temperature-rising method to prevent concrete temperature to be down to less than 0 DEG C, and this method cost is high, operating process is complicated; Two is admixture frostproofers in concrete, and the method construction is simple, and effect is also better, is therefore widely applied in China.
Up to the present, the pumping frostproofer used in domestic and international construction work is all with diminishing combination, then composite high-early strength component, antifreezing component and bleed component are formulated.Wherein diminishing component comprises naphthalenesulfonate formaldehyde condensation compound (naphthalene series high-efficiency water-reducing agent), sulfonated melamine compound condenses, sulfonated lignin; Early stage component comprises vitriol, carbonate, nitrate etc., and wherein majority is sodium salt; Nitrite, nitrate, villaumite, urea and ammoniacal liquor etc. are had in antifreezing component.Villaumite can to steel bar corrosion, and work-ing life is built in impact; The release such as urea, ammoniacal liquor irritating smell, affect quality of life, nitrite has carcinogenesis, and easily causes alkali-aggregate reaction in concrete, the bad phenomenon such as the accumulation of salt in the surface soil, and impact building uses and visual appearance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of concrete antifreezer, and this frostproofer is good to concrete adaptability, steady quality, product environmental protection, can adapt to various requirement of engineering, and concrete can be kept not freeze at-20 DEG C ~-30 DEG C.
For achieving the above object, the present invention adopts following technical scheme:
A kind of concrete antifreezer, be made up of the raw material of following weight part:
The polycarboxylate water-reducer that the present invention uses has excellent resistance to frost, redeployed concrete work performance can be made good, concrete can be kept not freeze at low temperatures.
The sodium lignosulfonate that the present invention uses has diminishing, slow setting, bleed three efficacy concurrently, significantly improves parcel performance, also can reduce the use of a part of water reducer simultaneously, cost-saving.
Alkyl glycoside in the present invention is synthesized by renewable resources natural fat alcohol and glucose, is the more comprehensive new non-ionic surfactants of a kind of performance.It has the characteristic of conventional nonionic and anion surfactant concurrently, there is high surface, good ecological security and intermiscibility, it is internationally recognized first-selection " green " functional surfactant, the stability of frostproofer can be improved, ensure the steady quality of frostproofer, can also early age strength of concrete be improved, improve concrete mobility.
Tea saponin, be a kind of excellent property non-ionic type pure natural tensio-active agent it there is stronger foaming, emulsification, dispersion, the effect such as wetting, and hardly by the impact of water hardness.Tea saponin forms a large amount of micro-bubbles, and when concrete use temperature is lower than predetermined, the water in concrete freezes, water is squeezed in bubble, the impact of concrete structure is significantly reduced, concrete later strength is not affected, ensure concrete later strength.
Sunmorl N 60S in the present invention has the function of retardant and water reducer, can increase concrete plasticity-and intensity.
Sodium dodecylbenzene sulfonate in the present invention significantly solves the adaptability problem of frostproofer and water reducer.
Calcium formiate of the present invention has mildew-resistant, antibacterial effect, prevents frostproofer mouldy.
Preferably, concrete antifreezer of the present invention, be made up of the raw material of following weight part:
Compared with prior art, beneficial effect of the present invention is:
Concrete antifreezer of the present invention has nontoxic, alkali-free, without chlorine, discharge without ammonia, diminishing is suitable, concrete slump keeps, time of coagulation is short, good with cement adaptability, remarkable improve concrete newly mix and stir sclerosis after performance, good to concrete adaptability, steady quality, the features such as product environmental protection, the regulation negative temperature conservation intensity of 7 days reaches more than 23% of normal curing in 28 days, negative temperature conservation transfers the normal curing intensity of 28 days to and reaches more than 150% of normal curing after 7 days, concrete is more durable for work-ing life, it is a kind of high performance concrete frostproofer, concrete can be kept not freeze at-20 DEG C ~-30 DEG C, various requirement of engineering can be adapted to, be specially adapted to the skeleton construction of north of china in winter construction.
