Embodiment

[0016] A high-performance alkali-free liquid quick-setting agent, prepared from the following raw materials in parts by weight: 450 parts of aluminum sulfate, 60-80 parts of magnesium sulfate, 5 parts of triethanolamine, 3 parts of sepiolite, 10 parts of diethanolamine, water 472 copies.

[0017] Magnesium sulfate is 80 parts during winter, and magnesium sulfate is 60 parts during all the other seasons. The dosage should be changed according to the changes of the seasons. In winter, 20 parts more can be added to adjust the viscosity.

[0018] Preferably, one portion is 1 kg, prepared from the following raw materials in parts by weight: 450 kg of aluminum sulfate, 5 kg of triethanolamine, 3 kg of sepiolite, 10 kg of diethanolamine, 472 kg of water, and 80-60 kg of magnesium sulfate. The specific dosage varies with the seasons Make corresponding adjustments, add 20kg more in winter to adjust the viscosity.

[0019] A preparation method for the above-mentioned high-performance ...

Abstract

The invention provides a high-performance alkali-free liquid accelerator. The high-performance alkali-free liquid accelerator is prepared from the following raw materials in parts by weight: 450 partsof aluminum sulfate, 60-80 parts of magnesium sulfate, 5 parts of triethanolamine, 3 parts of sepiolite, 10 parts of diethanolamine and 472 parts of water. The defects of a traditional accelerator are overcome, and the comprehensive use performance of the accelerator is improved.

Description

technical field [0001] The invention relates to the technical field of quick-setting agents, in particular to a high-performance alkali-free liquid quick-setting agent and a preparation method thereof. Background technique [0002] Accelerator is an admixture mixed into concrete that can make concrete harden quickly. The main types are inorganic salts and organic substances. It is a powdery solid. Its function is to accelerate the hydration and hardening of cement and form sufficient strength in a short period of time. Its dosage only accounts for 2% of the amount of cement in concrete. ~3%, but it can make the concrete set within 5 minutes and set within 12 minutes, so as to achieve the purpose of rapid repair or rapid setting of concrete in the shaft. It is an indispensable additive in the shotcrete construction method and ensures the special construction requirements. At present, the general quick-setting agents on the market mainly have the disadvantages of strong corro...
