| titleOfInvention | Nucleus type concrete early strength agent and preparation method thereof |
| abstract | A kind of nucleus type concrete early strength agent and preparation method thereof, the early strength agent that parts by weight are 1000 parts, which is made, is: 100~150 parts of polymer, 20~50 parts of sodium metasilicate pentahydrate, 60~90 parts of calcium nitrate tetrahydrate, remaining is deionized water.Preparation method: being added polymer into three-necked flask first, and deionized water is added later becomes bottom liquid, and flask is placed in hot bath, controls temperature, stirring；Sodium metasilicate pentahydrate is taken, deionized water is added in it, is configured to solution A；Calcium nitrate tetrahydrate is taken, deionized water is added in it, is configured to solution B；Solution A, solution B are added dropwise into bottom liquid for same rate simultaneously, and by product insulated and stirred after being added dropwise to complete, product is finally rapidly cooled to room temperature, obtained final product is nucleus type concrete early strength agent by reaction.Its performance is good, and concrete setting can be made fast, and demoulding time is short, is not easy the mould that collapses, and have certain water-reducing effect, and late strength of concrete loss is few. |
