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.

In one embodiment, a method of manufacturing a dry geopolymer formulation. The method comprises obtaining the various constituents of the geopolymer formulation from one or more of a sand, a ground granulated blast furnace slag (GGBFS), a fly ash, sodium tetraborate, a boric acid, a zeolite, a sodium caseinate, SC-9, sodium metasilicate and sodium hydroxide; and mixing the constituents to a homogenous mixture. In another embodiment, the present disclosure describes a method of manufacturing a building material comprising obtaining the dry geopolymer formulation, mixing the hydrated formulation, dispensing the formulation; and curing the formulation.

The present disclosure relates to a visible light-catalyzed translucent concrete, and a preparation method and use thereof. The preparation method includes: extracting an iron oxide from a copper slag, mixing the iron oxide with TiO.sub.2 to obtain a photocatalyst, and then mixing the photocatalyst with an additive to obtain a photocatalytic slurry; preparing a concrete slurry using the copper slag after iron extraction as an aggregate; and pouring the photocatalytic slurry, the concrete slurry, and the photocatalytic slurry in sequence into a mold pre-laid with an optical fiber, to obtain the visible light-catalyzed translucent concrete. In the visible light-catalyzed translucent concrete, iron in the copper slag is used as a part of raw materials of the photocatalyst, and the copper slag after iron extraction is used as an aggregate to replace natural sand and gravel. This solves environmental pollutions caused by the copper slag and realizes resource utilization.
