Method for preparing natural hydraulic lime by using limestone and quartz powder
The invention relates to a method for preparing natural hydraulic lime by using limestone and quartz powder, and belongs to a building material. The method is implemented by taking limestone as a main raw material through the steps of adding high-purity quartz powder to adjust the ratio of calcium oxide and silicon oxide, controlling the content of alumina, carrying out mixed material co-grinding for 6-10 hours by using a ball mill, adding water with a mass accounting for 8% of the mass of a mixed raw material, fully stirring, putting the obtained object into a sealing bag to place for 6-7 hours, pressing the obtained object into a cylinder, drying the cylinder by using a drying oven, putting the cylinder into a muffle furnace to calcinate for 3 hours at a temperature of 1100-1200 DEG C, cooling the calcinated material to room temperature in the air by air cooling, determining the free calcium oxide content of the calcinated product, adding a certain amount of water for slaking into the calcinated product, and after the slaking process is completed, obtaining desirable natural hydraulic lime.
