Abstract

See full text

Methods for producing pozzolanic or latent hydraulic cement clinker substitutes may involve calcining clay with a fuel comprising a mineral substance at temperatures in the range from 500 to 1250° C., preferably from 550 to 1150° C., most preferably from 700 to 900° C. A resulting mixture of mineral substance from the fuel and the calcined clay forms a pozzolanic or latent hydraulic cement clinker substitute, in which a fraction of the mineral substance incorporated into the pozzolanic or latent hydraulic cement clinker substitute by the fuel is 1-60% by weight.
