<p>Coal combustion product cement compositions produced using classes of relatively low-cost industrial by-products and low-value minerals. A variety of highly sustainable cements with low-environmental impact can be provided. Coal combustion by-products and other wastes produced on the large scale from the burning of coal or coal and biomass in coal-fired power stations with or without low-value minerals, processed minerals, and/or by-products of the mining, mineral processing, metal refining, petrochemical, fine chemical, pharmaceutical, agrochemical, biotechnology, food, feed and energy industries, as well as agricultural and municipal by-products, can be utilized to provide improved cements and cementitious materials that are more economic and environmentally friendly than traditional cements including Portland cement.
Coal combustion product cement is obtained upon physical combining or chemically reaching a by-product or low-value mineral with a reactant.</p> |
