Description
Technical field
The present invention relates to the adjustable concrete pumping frostproofer of a kind of performance, be applicable to that winter construction with using in commerical ready-mixed concrete, the pump concrete, belongs to building material field.
Background technology
In large-scale construction work, not only requiring has modern operating technique and construction means, simultaneously concrete has also been proposed the technical feature requirement of multiple function.For example, the commerical ready-mixed concrete of winter construction, the pump concrete of Highrise buildings for keeping its good working performance, need concrete to have resistance to frost, good like big fluidised form, slump retentivity, early strong, reinforced effects is good.Especially early strong intensity can shorten the concrete insulated curing time, reduced cost.And in the different environment engineering; According to the different functions needs; Winter construction then requires concrete to have requirements such as early strong or each age strength, and the raising of all these concrete technical features and improvement all realize through mixing the concrete pumping frostproofer.
Domestic and international existing pumping frostproofer kind is more, and what consumption was more is villaumite resistance rust type pumping frostproofer.This pumping frostproofer greatest drawback is to be used for the prestressed reinforced concrete engineering.With naphthalene water reducer, sulfamate water reducer and other antifreeze component compound frostproofer, water-reducing rate is not very high, and volume stability is poor.The pumping agent of single component, though pumping is effective, volume stability, resistance to frost, early strong poor performance.
Summary of the invention
The technical problem that the present invention solves is: prevent that concrete from enduring cold in early days, early-age shrinkage, improve concrete pumpability, improve early age strength of concrete and later strength that production technique is simple, cost is lower.
Technical solution of the present invention is:
The adjustable concrete pumping frostproofer of a kind of performance comprises the components in weight percent of following material: water reducer 28%-42%; Air entrapment agent 0.3%-0.7%; Liquid agent 0.05%-0.07%; Toughener 1.5%-2.5%; Frostproofer 2.0%-3.0%; Slump-loss suppressor factor 1.5%-5.0%; Water 45%-65%.
Said water reducer is naphthalenesulfonate formaldehyde condensation compound water reducer, sulfamate water reducer, aliphatic water reducing agent or polycarboxylate water-reducer or two or more combination.
Said air entrapment agent is triterpenoid saponin, 12 molten basic sodium sulfate or 12 molten basic Supragil GNs.
Said liquid agent is dibutylester or tri butyl ester.
Said toughener is water glass or Sulfothiorine.
Said frostproofer is methyl alcohol or terepthaloyl moietie.
Said loss suppressor factor is Sunmorl N 60S, Hydrocerol A or tripoly phosphate sodium STPP.
This concrete pumping frostproofer
Pumping frostproofer of the present invention, water-reducing rate is high, morning is strong, good effect of freezing protection, and volume is lower, material cost is low, has good economic benefit and social benefit.And can regulate raw-material cooperation ratio according to the request for utilization of different user, reach the different functions requirement.As: diminishing require, require antifreeze morning by force, different requirement time of coagulation, and alkali-free, chloride ion-containing not are to the effect of reinforcing bar non-corroding.
The invention effect
The present invention is the pumping frostproofer, through various performance tests and test, has following characteristics and function:
1) the present invention compares with other type frostproofer, and water-reducing rate is high, multiple functional, good combination property, early strong reinforced effects is good.After product of the present invention mixes concrete, can make concrete water-reducing ratio reach 25%-35%, pumpability is good.-7d compressive strength rate 10%-20%, 28d compressive strength rate 100%-120%, 28d shrinkage ratio are less than 120%, to the effect of reinforcing bar non-corroding.
2) pumping frostproofer production technique of the present invention is simple; Material cost is low; In concrete, use winter and have the low characteristics of volume; Have also that effective, the big fluidised form of early-strength anti-freezing, pump-conveying property are high, air content is moderate, improve mechanical performance of concrete, slump-loss is little, improves concrete workability comprehensively.The concrete surface shrinkage crack of moulding is few, can comprehensively improve concrete impermeability, frost resistance, anti-carbonization property and endurance quality or the like.
