It聽is the raw material of cement industry, also known as cement additive. As a retarder, the amount of fluorogypsum is about 5% of cement.聽 Compared with natural gypsum, the chemical composition of fluoro-gypsum is stable and close to the chemical composition of natural gypsum, so fluoro-gypsum instead It has been widely used as cement retarder and mineralizer instead of natural gypsum, and it has become the main way to treat fluoro-gypsum in recent years.The results show that the use of fluoro-gypsum as cement retarder can not only achieve the same retarder effect as natural gypsum, but also improve the strength of cement without other side effects. Using fluorite-聽fluorogaster as the compound mineralizer of calcined cement slurry, the factory test shows that the compound mineralizer of fluorogaster calcined slurry has stable physical properties, the setting time, stability qualification rate and strength of clinker are better than the original clinker, and the mineralization effect is better.wholesale Gypsum website: [***] |
