Abstract
The invention provides highly efficient antifreeze used for cement concrete, which has the advantages of a small intermingled quantity of the antifreeze in concrete, good water-solubility, no chlorine, harmlessness and inexpensive price. The concrete has great high strength at early stage, sodium sulfate is used instead of chloride, thereby ensuring that metals are not corroded and are not toxic. The highly efficient antifreeze can not only be applied to the construction of ordinary concrete in winter, but also to the construction of pumping concrete and commercial concrete. The antifreeze has the advantages of good performance, wide application and high efficiency.
Description
Technical field: the present invention relates to a kind of high-efficiency antifreezing agent that is used for cement concrete, belong to building material field.
Background technology: along with speeding up of modernization development, building not only requires the quality height but also requires speed fast, and northern China concreting in cold-weather problem is the fast-developing bottleneck of restriction building in the north industry always.The insulation measure cost of in the past taking is too high.It is a kind of with low cost adding frostproofer by comparison, effective good method.
The frostproofer of Shi Yonging was based on villaumite in the past, and compound Sodium sulfate anhydrous.min(99) and tensio-active agent form, and its shortcoming is that villaumite is serious to metallic corrosion, influences reinforced steel bar strength, influences the concrete durability degree, and should not promote; Another kind of is that the urea compound nitrite is the main antifreezing component, compound other fillers, and this kind frostproofer price height, volume is big, drug effect is low, and harmful.
Invent a kind of do not have chlorine, harmless, volume is little, metal is not had the cheap high-efficiency antifreezing agent of burn into is purpose of the present invention.
Summary of the invention: the invention provides a kind of new high-efficiency antifreezing agent, be characterized in that its volume in concrete is little, good water solubility, no chlorine, harmless, cheap, early age strength of concrete is high, select for use sodium sulfate to substitute villaumite, to metal non-corroding, nontoxic.Be not only applicable to the normal concrete winter construction, and be applicable to pump concrete and commerical ready-mixed concrete winter construction, excellent performance, applied widely, the service efficiency height.
Each composition of the present invention by mass ratio is: sodium sulfate (2-50%), calcium formiate (2-40%), six water acetic acid magnesium (2-20%), organic alcohol amine (5-20%), low-carbon alcohol (2-20%).
Used organic alcohol amine can be trolamine, diethanolamine, tri-isopropanolamine; Used low-carbon alcohol can be ethylene glycol, glycerol, 2-propylene glycol.
Embodiment 1: sodium sulfate (40%), calcium formiate (20%), six water acetic acid magnesium (20%), trolamine (10%), ethylene glycol (10%).
Embodiment 2: sodium sulfate (30%), calcium formiate (30%), six water acetic acid magnesium (20%), diethanolamine (10%), glycerol (10%).
Embodiment 3: sodium sulfate (50%), calcium formiate (20%), six water acetic acid magnesium (10%), tri-isopropanolamine (10%), 2-propylene glycol (10%).
Embodiment 4: sodium sulfate (45%), calcium formiate (25%), six water acetic acid magnesium (15%), tri-isopropanolamine (10%), ethylene glycol (5%).
Embodiment 5: sodium sulfate (25%), calcium formiate (35%), six water acetic acid magnesium (20%), diethanolamine (10%), ethylene glycol (10%).
Embodiment 6: sodium sulfate (35%), calcium formiate (35%), six water acetic acid magnesium (20%), trolamine (5%), glycerol (5%).
