Apt to cake after moisture absorption when laid in air for a long time.A little green because of Fe2+ ,yellow when Fe2+ is oxided to Fe3+.Soluble in water easily,and water solution is acid.
- Aluminum sulfate can be used to produce cement reinforcement and as accelerator .
2. The proportion of aluminum sulfate used in the production of cement reinforcement is 40-70%.
3. Aluminum sulfate is a typical representative of aluminum salt, so it has some characteristics of aluminum salt. In the process of making cement, aluminum sulfate is mixed in cement mortar and then fully stirred. After a period of time, aluminum sulfate will be mixed with cement mortar. The hydrated products react chemically, and the products are aluminum hydroxide and iron hydroxide. These two substances are colloidal and will not dissolve in water. Aluminum sulfate will also undergo chemical changes with calcium hydrated aluminate in the cement to form a chemical substance with an expansion effect. During the production of cement, these generations The colloidal and expansive substances fill the cement with small gaps in the hardening stage, so the density of the cement will be greater and stronger, and its waterproof performance and impermeability will be better. Therefore, aluminum sulfate plays a role as a waterproofing agent in the production of cement. During production, aluminum sulfate is added to the cement slurry in a certain proportion, so that the produced cement is smeared on the surface of the building to play a permanent waterproof and moisture-proof role.
