Abstract
In one embodiment, a building material derived from a geopolymer formulation comprises sand, ground granulated blast furnace slag (GGBFS), fly ash, sodium tetraborate, boric acid, zeolite, sodium caseinate, and SC-9. Optionally, the formulation also comprises additional constituents like sodium metasilicate, sodium hydroxide, magnesium oxide, hemp, basalt fibers, aggregates, and fillers. The building materials have high compressive strength, flexural strength, tensile strength, impact resistance, and thermal resistance.
Claims21
A building material derived from a geopolymer formulation comprising:
- a sand, a ground granulated blast furnace slag (GGBFS), a fly ash, sodium tetraborate, a boric acid, a zeolite, a sodium caseinate, SC-9, and one or more of sodium metasilicate and sodium hydroxide;
