(57) Alkali-activated concrete having a glassy surface finish, and methods and products related to the same. A substrate comprising the alkali-activated concrete is finished with a glassy surface finish that is vitrified and adheres to the substrate, for example by glazing or enameling with a suitable firing process. A mixture for the alkali-activated concrete has a cementitious binder, an alkali activator, and an aggregate. The alkali-activated concrete formed from the mixture has a high thermal resistance that is able to withstand the temperatures and thermal shock required during a suitable firing process for minerals of glazes and enamels thereon to vitrify and adhere to a surface of the alkali-activated concrete without cracking or breaking apart. The alkali-activated concrete may include geopolymers and/or inorganic polymers.
