| titleOfInvention | A kind of β semi-hydrated gypsum retarder and preparation method thereof |
| abstract | The present invention relates to a kind of β semi-hydrated gypsum retarder and preparation method thereof by mechanical grinding, to be mixed to get inorganic compounding retarder with zeolite, metallurgical slag (manganese slag, steel slag or slag etc.) for primary raw material；Preparation section is simple, at low cost, resultant effect is good.The present invention gives full play to the synergistic combination effect between each material of zeolite, metallurgical slag, cement, it is adjustable the setting time of β semi-hydrated gypsum, compared with the retarder such as traditional sodium citrate, calgon, gypsum material loss of strength is small, moreover it is possible to effectively improve the water resistance of gypsum material；Not only gypsum performance had been improved, but also can effectively solve the problem of metallurgical slag accumulation pollutes environment, has realized and makes the best use of everything. |
