用自然煤矸石、硫酸铝渣及沸石生产复合水泥

Study on the Production of Composite Portland Cement with Burnt Coal Waste,Aluminium Sulfate and Zeolite

天然沸石是一种较好的活性混合材料 ,生产时掺入可以改变水泥性能 ;另外 ,煤矸石、硫酸铝渣等工业废渣如果用于生产水泥 ,既可以降低水泥成本 ,又可以保护环境。通过试验研究和生产实践证明 ,合理搭配使用天然沸石、煤矸石。

Natural zeolite is a better active blending material for cement production. It can reduce cost and has better cement performance. Industrial residues such as coal waste,aluminium sulfate residue and so on can not only reduce cost but also protect environment against pollution when using for cement production . The feasibility of using these industrial residues for cement production is proven through the experiments of adding in coal waste,aluminium sulfate residue,and it can obtain better result in production practice.
