Marine Concrete from Granulated Phosphorite Slag Cement

摘要

Development of the offshore phosphorite deposits in the Pacific shelf isrnactual now. Extraction of phosphorus is proposed using electrothermalrnsublimation technology. Such method is accompanied by thernproduction of large amount of slag materials which can be used forrnfabrication of high quality building materials. These include the slagrncements without or small content of clinker, foam glass, slag pumice,rnslag fibers, glass etc. The paper presents the test results relating torncorrosion resistance of concrete with slag cement with the addition ofrnphosphorus slag by the technology of the electrothermal sublimation.
