用钡元素或锶元素部分取代硫铝酸钙矿物中的钙元素,形成一系列新型硫铝酸钡(锶)钙衍生矿物,这些矿物烧成温度低,具有良好的快硬早强、微膨胀和耐侵蚀等性能,本文对该特种水泥进行了系统介绍,对新型水泥矿物晶体学特性、矿物制备及水化等理论基础进行阐述,介绍了硫铝酸钡(锶)钙水泥在力学、防腐、抗渗等方面的突出优势,以及通过矿物复合技术合成阿利特-硫铝酸钡(锶)钙水泥、贝利特-硫铝酸钡(锶)钙等新型高性能水泥。另外,还介绍了该系列水泥在实际工程中的应用情况,结果表明其具有较高的恶劣环境适应能力。
Partial substitution of barium or strontium for calcium in sulphoaluminate minerals results in the formation of a series of new barium sulphoaluminate (strontium) derived minerals that have a low firing temperature, good fast and harden early strength, slightly expanded And erosion-resistant properties, this paper introduces the specialty cement systematically, elaborates the theoretical foundation of new cement mineral crystallography, mineral preparation and hydration, introduces the application of barium sulphoaluminate (strontium) calcium cement in mechanics, corrosion protection , Impermeability and other outstanding advantages, as well as through the mineral composite technology Alite - barium sulphoaluminate (strontium) calcium cement, Bailey - barium sulphoaluminate (strontium) calcium and other new high-performance cement. In addition, the application of this series of cement in the actual project is also introduced. The results show that it has high harsh environment adaptability.
