| titleOfInvention | Waterproof enhanced alkali-free liquid accelerator and preparation method thereof |
| abstract | The invention relates to the technical field of building materials, in particular to a waterproof enhanced alkali-free liquid accelerator and a preparation method thereof. The accelerating agent comprises a modified aluminate solution, a stabilizer, a pH regulator, magnesium dihydrogen phosphate and water; the preparation method of the modified aluminate solution comprises the following steps: adding stearic acid into a reaction kettle, heating to 70-80 ℃, heating to a molten state, starting a stirring device, adding ammonia water for reaction, cooling to 35-50 ℃, adding aluminum sulfate, aluminum isopropoxide and water into the reaction kettle, carrying out ultrasonic reaction, cooling to normal temperature, and adding calcium hydroxide for reaction to prepare the modified aluminate. The accelerator is used for synthesizing an alkali-free liquid accelerator, the prepared alkali-free liquid accelerator has a waterproof function, the durability of concrete can be improved, the rebound rate of the concrete is low, the stability of a product can be improved, the early and later strength of sprayed concrete is obviously improved, and the alkali-free liquid accelerator has important practical application value in the aspect of concrete construction. |
