| titleOfInvention | Preparation method and application of calcium carbonate nano-slurry with different crystal forms |
| abstract | The invention provides a preparation method and application of calcium carbonate nano-slurry with different crystal forms, wherein the preparation method comprises the following steps: preparing a calcium salt solution and a carbonate solution by adopting a solvent, and doping a surfactant into the prepared solution; slowly pouring the prepared calcium salt solution and the carbonate solution into a reactor at the same speed and uniform speed to react quickly to obtain mixed slurry; and standing and aging the mixed slurry for 18-36 h, washing and centrifuging by using deionized water until the pH of the mixed slurry is neutral, and thus obtaining calcium carbonate nano-slurry with different crystal forms. The calcium carbonate nano-slurry with different crystal forms prepared by the invention is used as an early strength agent to be added into a cement-based material, so that the early strength of cement can be obviously improved, and compared with the early strength of the cement without the nano-slurry, after the aragonite and calcite mixed crystal form nano-slurry is added, the 1d compressive strength improvement rate of the common portland cement is up to 30%. |
