Process for producing building binders and products from fly ash obtained by combustion of solid fossil fuels

摘要

the invention relates to the production of construction materials and the way product from fly ash derived from combustion of solid fossil fuels, whose essence is thethe fly ash obtained by burning the solid fossil fuels will crush on rudeness grains under 100 micrometer, together with vysusenu00fdm clay in the mnozstvu00ed 5.00% az 80,00%, vztazeno on the weight of the fly ash.dry or in presence of water and pridu00e1 to go with chemical aktivacnu00ed pru00edsada, able to add alkali metal and alkaline earth metal ions or / and increased ph in the mnozstvu00ed 0,10% az 15.00%.vztazeno weight fly ash or its aqueous solution or / and zahru00edvu00e1 for the presence of water at temperature of 70 to 100.degree.c.degree.c under atmospheric pressure or in an autoclave at a temperature of 100.degree. c and 400.degree.c pressure 0.1 mpa or to 50 mpa to obtain a dry construction material or capable of being moulded wet construction mass, which possibly shapes to pozadovanu00e9ho shape construction product.
