| titleOfInvention | A kind of antifreeze type alkali-free liquid accelerator and preparation method thereof |
| abstract | The invention provides an antifreeze type alkali-free liquid quick-setting agent, which is prepared by the following method: taking hydrophilic gas-phase silica, making it uniformly dispersed in water, and then adding iminodisuccinic acid or its salt, aluminum sulfate , pseudo-boehmite, stir for at least 30min, after stirring, add ethylene glycol, triisopropanolamine, alkylbenzene sulfonate, lignin sulfonate, stir to make it evenly mixed, and adjust the pH of the entire system Adjust to 6‑8. The antifreeze-type alkali-free liquid quick-setting agent of the invention can speed up the initial setting and final setting speed of concrete, and increase the 1d compressive strength of cement stone and the retention rate of compressive strength in the later period. |
