Abstract
Chemically bonded ceramics and manufacturing processes are described. In one aspect, a manufacturing process of a chemically bonded ceramic is carried out by: (1) combining an acidic liquid and Fly ash to form a mixture; and (2) curing the mixture to form the chemically bonded ceramic. The Fly ash corresponds to at least a majority by weight of solids combined with the acidic liquid to form the mixture.
Claims13
A manufacturing process of a chemically bonded ceramic, comprising:
- combining an acidic liquid and Fly ash to form a mixture, wherein the Fly ash corresponds to at least a majority by weight of solids combined with the acidic liquid to form the mixture;
- and
- curing the mixture to form the chemically bonded ceramic,
- wherein the Fly ash corresponds to at least 90% by weight of solids combined with the acidic liquid to form the mixture,
- wherein curing the mixture is carried out at a temperature up to 110° C., and
- wherein a compressive strength of the chemically bonded ceramic is at least 15 MPa,
- further comprising placing the mixture in a mold, and wherein curing the mixture is at least partially carried out with the mixture placed in the mold.
