Influence of SO3 from CFBC Coal Ash on Setting Time of Cement

来源 :The 8th International Symposium on Cement & Concrete(ISCC 20 | 被引量 : 0次 | 上传用户：ccnuzgq1

【摘 要】

：

As the Circulated Fluidized Bed Combustion(CFBC)coal ash has high SO3 content,when used as cement admixture with gypsum,the SO3 content in cement easily goes beyond the limit.
