Abstract

The invention relates to a chlorine salt-free ammonia-free liquid concrete anti-freezing pumping agent, which comprises the following raw materials by weight: 250-300 parts of high concentration naphthalene series high efficiency water reducer; 10-35 parts of glycol, 10-15 parts of maltodextrin, 60-100 parts of methanol, 80-120 parts of sodium thiosulfate, 30-80 parts of sodium nitrite, 1-5 partsof sodium abietate and 400-600 parts of water. The concrete anti-freezing pumping agent has the characteristics of no chlorine salt containing, no corrosion on steel bars, no ammonia containing and no exceeding standard of ammonia in buildings; and the researches found that the anti-freezing pumping effect substantially exceeds the expectation of the technical staffs.

Description

Technical field [0001] The invention relates to the technical field of concrete, in particular to an antifreeze pumping agent for liquid concrete without chlorine salt and ammonia. Background technique [0002] Antifreeze is an admixture that can harden concrete at negative temperature and achieve expected performance under specified curing conditions. It is a substance that can prevent the moisture in the material from freezing at low temperatures. The use of antifreeze can significantly reduce the energy consumption of building construction in winter, and can ensure that the concrete can still set and harden normally under negative temperature. [0003] The antifreeze used in the construction of concrete buildings is currently mostly chloride salt antifreeze, chloride salt anti-corrosion antifreeze, and ammonia water reducer. The chloride salt antifreeze has a corrosive effect on steel bars, and the role of chloride salt anticorrosive antifreeze in humid environments Under the ...
