固废制备高贝利特硫铝酸盐水泥的研究进展

高贝利特硫铝酸盐水泥具有早期强度高、后期强度发展好的特点,生产能耗低且CO2排放量少。从固废原料的利用、水泥制备工艺与水泥性能3个层面,综述了固体废弃物制备高贝利特硫铝酸盐水泥的研究现状;并提出固废制备高贝利特硫铝酸盐水泥需进一步研究和解决的问题,如大宗固废原料的利用、全固废制备技术及固废重金属固化、溶出评价等,亦为今后理论研究与实践发展的新路径。

Research progress on preparation of high Belite sulphoaluminate cement with solid waste

High Belite sulphoaluminate cement has characteristics of high early strength and late strength development,besides low production energy consumption and CO2 emissions.It was elaborated on research status of high Belite sulphoaluminate cement prepared with solid waste from the utilization of solid waste materials and cement preparation technology as well as cement properties.The problems needed further research and solution were put forward,which is also a new path of the development of theoretical research and practice in the future,such as utilization of bulk solid waste materials,all solid waste preparation technology,and solidification and dissolution evaluation of heavy metals in solid waste,etc.
