THE POSSIBLE USE OF INDUSTRIAL WASTE IN THE MANUFACTURE OF AN HYDRAULIC CEMENT

This paper describes the results of a factorial experimental design study into the possible use of industrial waste as feedstock for the manufacture of hydraulic cement. A survey of some currently available waste materials is presented and research techniques used to select those most suitable are described. These include particle size distribution, scanning electron microscopy and x-ray diffractometry. The design and subsequent analysis of a statistically based factorial experiment is discussed. Hence, the influence of a number of variables on the production of conventional hydraulically cementitious phases is determined. Such variables include mix proportion, effect of fluxing agent, firing temperature and time. Results indicate that industrial wastes can produce the required phases, i.e.: dicalcium and tricalcium silicates and tricalcium aluminate. Further the amounts and rate of their formation is shown to depend on the feedstock materials, their relative proportion, the firing temperature used and the presence of added fluxing agents. However, the influence of extended firing times was found to be negligible. (Author/TRRL)
