PROCESS FOR PRODUCING CEMENT OR CEMENT SUBSTITUTES

摘要

This invention relates to a process for producing cement or cement substitutes on the basis of carbon-containing compounds with a carbon content of more than 10 wt-%, wherein the carbon-containing compounds are burnt in a furnace at a temperature of 600 to 900°C, and wherein beside the carbon-containing compounds at least one additional, inert and/or low-heating-value material, which already before or after a thermal treatment has cement properties, is introduced into the furnace and calcined.
