钛白渣作水泥缓凝剂的应用研究

目前天然石膏供不应求、价格飞涨，其很大比例是用做水泥缓凝剂。为解决这一矛盾，本文从石膏缓凝剂的缓凝机理入手，对钛白粉生产过程中钛白渣的化学成分、在水泥中与天然石膏的性能对比试验、最佳掺量等方面情况进行分析研究，得出钛白渣可以替代天然石膏作水泥缓凝剂、其最佳掺量为5％～6％等结论，为资源的综合利用和水泥企业缓凝剂选择开拓了新的道路。

RESEARCH THE APPLICATION OF TITANIUM WHITE RESIDUE AS SET RETARDER IN CEMENT

In recent years, natural gypsum supply falls short of demand, price soars rapidly, its very large proportion is used to do set retarder of the cement. In order to solve this problem, the paper starts from the gypsum retardant mechanism of set retarder, to analysis and study the titanium white residue chemical component in the process byproduct of titanium white powder, the function compare experiments in cement with the natural gypsum, the best addition, etc. the conclusions are that titanium white residue can act as the natural gypsum to make set retarder in cement, and its the optimization addition is 5%-6%, etc, the paper explore the new road for synthesize utilizing the resources and choosing set retarder of cement enterprises.
