Report on a Preliminary Technical Feasibility Study into the Disposal, Storage and Utilization of Industrial Waste Gypsum

摘要

A preliminary study was made of waste gypsum from the phosphoric acid industry in the RSA with a view to investigating present methods of disposal of waste gypsum at the various plants and alternative methods of disposal, with particular reference to the stability and containment of solid material and the control of effluents and also gaining information about the nature of the material from a point of view of utilizing it in the building and construction industries, with particular reference to using it as a set regulator in portland cement and for the manufacture of building units and portland cement. The work was done with financial assistance from the Cooperative Scientific Programmes Unit of the Council for Scientific and Industrial Research.
