Method for preparing magnesium oxide light and calcium oxide light and application thereof in preparation of calcium-magnesium composite expanding agent |
| abstract |
Method for preparing magnesium oxide light and calcium oxide light using dolomite and application thereof in the preparation of a calcium-magnesium composite expanding agent. Magnesium oxide and calcium oxide are effectively separated by a one-step method using a decomposition temperature difference bewteen magnesium oxide and calcium oxide during a dolomite calcination decomposition process and a difference in the weight of the decomposed material. The preparation of a calcium-magnesium composite expanding agent using magnesium oxide light and calcium oxide light resolves the problem of limitations in the origin of a magnesium expanding ingredient in the calcium-magnesium composite expanding agent, i.e., the magnesium oxide light, and the problem of quick hydration reaction rate and low effective expanding efficiency of a calcium expanding ingredient in the calcium-magnesium composite expanding agent, i.e., free calcium oxide, thereby optimizing an expanding process of directly calcinating dolomite to produce a calcium-magnesium composite expanding agent. |
