Abstract: 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 TiO2 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.

Abstract: The invention belongs to the technical field of the resource treatment of industrial wastes, and particularly relates to a method for preparing a cementing material using smelting industrial waste slag after utilizing the simultaneous removal of SO2 and NOx in flue gas and an application of the cementing material obtained by the same. According to the invention, SO2 and NOx in the flue gas can be treated with the smelting industrial waste slag, meeting requirement of flue gas desulfurization and denitration; moreover, the smelting industrial waste slag can be purified and separated by means of waste gas resources to obtain a cementing material, realizing the resource utilization of the smelting industrial waste slag and waste gas.
