The mineral composition of aluminate cement is characterized by a large amount of calcium sulfoaluminate minerals, which is different from other series of cements. Moreover, aluminate cement has the basic characteristics of early strength, high strength, high impermeability, high frost resistance, corrosion resistance, low alkali and low production energy consumption. Aluminate cement is widely used in various construction projects (especially winter construction projects and emergency repair projects), seaport projects, underground projects, as well as various cement products and prefabricated components. The future prospect of sulphoaluminate cement is very good.
Portland cement has been used for construction of marine engineering, but sulfate and chloride in seawater will cause corrosion and damage to Portland cement minerals and steel bars. Concrete strength can be greatly reduced, causing structural damage, especially in splash zones. Therefore, people have to apply anti-corrosion coatings such as epoxy resin on the concrete surface, but this not only increases the construction process and material cost, but also requires continuous maintenance. The sulphoaluminate cement has excellent anti-corrosion properties in seawater, and its strength in seawater will not decrease, but will increase.
Due to the over-exploitation of the mine, the ground has collapsed, the groundwater level has dropped, and the surface plants have dried up, which has seriously affected the local ecological environment and agricultural production. The self-connecting top filling of the goaf is an important part of the green mining of the mine, and it is also the key work of the ecological restoration of the mine. At this time, the characteristics of high water base, early strength, high strength and micro-expansion of sulphoaluminate cement can be fully utilized, and the sulphoaluminate cement-based filler with self-connecting function can be successfully applied to mining projects in such areas. It has played an important role in the green mining of mines.
