Abstract
The invention discloses a concrete antifreeze pumping agent comprising the following raw material components, by weight: 15-20% of a water reducing agent, 8-12 percent of an antifreeze component, 2-5% of fluorosilicate, 0.6-1.0% of an early strength agent, 0.03-0.08% of an entraining agent, and 65-70% of tap water. The pumping agent provided by the invention is characterized in that the pumping agent can satisfy construction requirement under an environment with a temperature of -20 DEG C, and comprehensive indicators such as pumpability and early strength are substantially better than those of similar products in the market. The pumping agent provided by the invention has the advantages of high adaptability, high cost performance, no chlorine, and low alkali. The pumping agent is in a liquid state, such that the pumping agent is convenient to store, transport and utilize.
Description
Technical field
What the present invention relates to is a kind of research and development technology field of concrete admixture, is specifically related to a kind of concrete antifreezing pumping aid prepared for main raw material with phosphate fertilizer by-product product silicofluoride, prepares the concrete of various strength grade under being applicable to subzero temperature in winter.
Background technology
The vast northern area weather of China is usually colder, is 4 ~ 6 months winter, very large on concrete engineering construction impact.In order to ensure concrete construction quality and progress, concrete agitation station often selects hardening accelerator, frostproofer and water reducer separately to add to reach diminishing, antifreeze and early strong object, thus makes working procedure loaded down with trivial details and should not preserve, transport and use.Study a kind of liquid concrete anti-freezing pumping agents, to guarantee construction engineering quality and quickening speed of application, there is positive effect.
Summary of the invention
The object of the invention is to develop a kind of a kind of concrete antifreezing pumping aid being applicable to concrete batching under subzero temperature in winter to improve the deficiencies in the prior art.
Technical scheme of the present invention is: a kind of concrete antifreezing pumping aid, is characterized in that: the mass percent that its feed composition and each component account for raw material total amount is as follows:
Preferably above-mentioned water reducer is the one in polycarboxylate water-reducer, water soluble resin sulfonate water reducer or ligno-sulfate based plasticizer.More preferably described polycarboxylate water-reducer is the one in methacrylic acid-acrylic acid methyl esters polycarboxylate water-reducer, allyl ethers polycarboxylate water-reducer or amide-imide polycarboxylate water-reducer; More preferably described water soluble resin sulfonate water reducer is the one in sulfonated melamine compound resin water reducer, the ancient grand resin water reducer of code of sulfonation or polystyrene sulfonic acid resin water reducer.More preferably described ligno-sulfate based plasticizer is the one in calcium lignin sulfonate water depressor, sodium lignin sulfonate water reducer or magnesium lignosulfonate water reducer.
Preferably described antifreezing component is the one in Sodium Nitrite, Sulfothiorine or ethylene glycol.Preferably described silicofluoride is the one in silicofluoride magnesium, Sodium Silicofluoride or potassium silicofluoride.Preferably described hardening accelerator is the one in trolamine, tri-isopropanolamine or sodium sulfate.Preferably described air entrapment agent is the one in rosin thermopolymer air entrapment agent, sodium abietate or alkyl sodium sulfonate.
The preparation method of above-mentioned concrete antifreezing pumping aid is: take each raw material by weight percentage; Then each raw material taken is placed in forced action type mixing machine and mixes, namely obtain concrete antifreezing pumping aid.
Beneficial effect:
Concrete antifreezing pumping aid prepared by the present invention is main raw material owing to have employed phosphate fertilizer by-product product silicofluoride, thus this finished product low, decrease environmental pollution.Concrete antifreezing pumping aid of the present invention, volume is only 3% ~ 4% of gelling material, construction requirement can be met under the environment of-20 DEG C, the overall target such as pumping, early strength is obviously better than market like product, and strong adaptability, cost performance are high, without chlorine, low alkali, liquid, be convenient to storage, transport and use.
