| titleOfInvention | Polymerized aluminum phosphate series chlorine-free sulfur-free liquid alkali-free setting accelerator and preparation method thereof |
| abstract | The invention discloses a polymerized aluminum phosphate series chlorine-free sulfur-free liquid alkali-free setting accelerator and a preparation method thereof, and relates to the technical field of alkali-free setting accelerators. The alkali-free accelerator comprises the following components in percentage by mass: 50-60% of phosphoric acid, 10-15% of bauxite, 5-10% of magnesium fluosilicate, 2-4% of magnesium hydroxide, 2-4% of diethanol amine, 2-6% of a condensing agent and water to be supplemented to 100%. The accelerator is mainly applied to sprayed concrete, and the dosage of the accelerator is 5-7% of that of a cementing material. The accelerator has good stability, is free from layering and precipitation crystallization after being placed at room temperature and low temperature (5 ℃) for 3 months, and has no change in use effect; because the concrete has no alkali metal ions, no chloride ions and no sulfate ions, the corrosion to steel bars in the concrete and alkali aggregate reaction are reduced, the durability of the sprayed concrete is improved, the 28-day compressive strength ratio is more than 100% under the compatibility reaction of a condensing agent, and the requirements of first-class products in JC477-2005 can be met. |
