<p>The invention relates to the use of a mortar prepared from a mixture of anhydrite binder, sand, fluidised-bed ash from the combustion of sulphur containing fuels, especially coal, water and usual additives, for producing cement floors. As compared with the state of the art, the invention not only leads to a cost reduction in the production of anhydrite binder cement floors but also contributes to environmentally acceptable disposal of the ash dumps arising in the fluidised-bed combustion of coal. The resulting cement floor has advantageous technological properties, in particular with respect to the bending tensile strength and the degree of swelling. </p> |
