Abstract

See full text

A method for producing a cement material wherein 1) a first acid is reacted with a first cement precursor to form a second cement precursor, and 2) the second cement precursor is converted to a cement material. The first cement precursor includes one or more of Ca, Si, or Al, and the reaction with the first acid produces a second cement precursor that includes one or more of Ca, Si, or Al, and the conjugate base of the first acid. The second step can be performed by thermally converting the second cement precursor to a cement material by sintering or thermally decomposing the second cement precursor at a temperature in the range of 500 to 2000° C. The first step can be performed in the presence of water as a wet slurry. The concentration of the first acid can be greater than 20% by weight.
