Abstract

The invention discloses a solid waste unfired water permeable brick and a preparation method thereof, and belongs to the technical field of building materials, the water permeable brick is composed ofthe following components by weight: 22-30 parts of phosphorus slag, 15-23 parts of alkaline slag, 6-10 parts of silica fume, 17-20 parts of fly ash, 8-10 parts of epoxy resin, and 10-15 parts of water. Alkaline slag and phosphorus slag adopted by the method belong to solid waste produced by factory production, and the solid waste is recycled and then treated to a certain extent for reuse, so thatenvironmental pollution caused by the phosphorus slag and the alkaline slag is reduced. Meanwhile, the utilization rate is also improved; chlorine in the alkaline residues is removed through a waterwashing method, water washing is conducted three times or more according to the water-solid ratio of 6: 1, pollution of chloride ions to the environment is prevented, and meanwhile the compressive strength and breaking strength of the water permeable brick are improved.

Description

technical field [0001] The invention relates to a solid waste burn-free permeable brick and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Phosphorus slag is a kind of low melting point slag that is discharged regularly in the furnace when yellow phosphorus is produced by electric furnace method. About 8-10t of phosphorus slag is discharged for every 1t of yellow phosphorus produced. There are about 60 small and medium-sized yellow phosphorus factories in China all over the country. With the massive discharge of phosphorus slag, the environmental pollution is aggravated. In order to use phosphorus slag more effectively, my country formally formulated and implemented "GB6645-86 for granulated electric furnace phosphorus slag in cement" in 1986. Not much, effective use of phosphorus slag, turning waste into wealth, has obvious social and economic benefits, and has a broad prospect. [0003] Alkali slag is ...
