The Research on Preparation of Binding Material and Concrete with Desulphurization Gypsum

Abstract:

The binding material and concrete are prepared by desulphurization gypsum, cement, stone, sand and admixture. The performances of binding material are studied in the paper. The experimental results showed that it is absolutely feasible to prepare binding material by using cement, desulphurization gypsum and superplasticizer after drying and screening of desulphurization gypsum. The binding material was prepared by adding desulphurization gypsum replacing 10 percent cement and superplasticizer. the cement micellae compressive and bending strength of the binding material can meet the standard requirements of P.O42.5 and the binding material’s set time and soundness are up to standard. The concrete was prepared by adding desulphurization gypsum replacing 30 percent cement and superplasticizer. The concrete’s strength is up to standard of the C30 concrete, and its impermeability meets the requirement of P12. To execute the research can not only massively use waste sludge desulphurization gypsum but also solve environmental pollution.
