PRODUCTION OF CEMENT ADDITIVES FROM COMBUSTION PRODUCTS OF HYDROCARBON FUELS AND STRENGTH ENHANCING METAL OXIDES
The present invention provides combustion products of hydrocarbon fuels and controlled amounts of metal oxide strength enhancing materials. The combustion products are useful as additives to cementitious materials. A hydrocarbon fuel such as coal is introduced into a combustion chamber (12) and selected amounts of materials comprising CaO, SiO2 and Al2O3 are also introduced into and/or downstream from the chamber (12). The hydrocarbon fuel undergoes combustion while the metal oxide strength enhancing materials react with each other and/or the ash or other reaction products of the hydrocarbon fuel. The combustion products have been found to significantly increase compressive strengths of cements such as Portland cement. A reduction in SO2 emission levels also results from the introduction of the metal oxide strength enhancing materials into the combustion process.
