Abstract

The invention belongs to the technical field of building materials, and specifically relates to water seepage bricks, in particular to a low-energy-consumption sintering water seepage brick using industrial waste residues as a main raw material and a manufacturing method of the low-energy-consumption sintering water seepage brick. The low-energy-consumption sintering water seepage brick comprises the following raw materials in parts by weight: 50-70 parts of blast furnace granulated slags, 20-50 parts of coal gangue, 2-5 parts of a solubilizer, 2-5 parts of a plastifier and 2-10 parts of a binder. According to the low-energy-consumption sintering water seepage brick disclosed by the invention, the blast furnace granulated slags and the coal gangue are compounded to prepare the sintering water seepage brick, so that the utilization rate of the blast furnace granulated slags can be effectively increased, the recycling clean high-value utilization of solid waste is realized, and the trash utilization and the sustainable development of resources are realized. According to the low-energy-consumption sintering water seepage brick disclosed by the invention, a granulate stacking method and a hole making agent method are united for use, and loose porous structure of the blast furnace granulated slags and high-carbon-content coal gangue can be used as a hole making agent, so that the intensity is guaranteed, besides, the opening communication hole rate can be increased as much as possible, the infiltrability is improved, and the water seepage brick with high permeability is manufactured.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and in particular relates to a water seepage brick, in particular to a low-energy sintered water seepage brick with industrial waste residue as the main raw material and a manufacturing method thereof. Background technique

[0002] Blast furnace water-quenched slag is a kind of loose and porous particles formed when the molten slag is water-quenched and quenched during blast furnace smelting. Each ton of pig iron will produce 0.25 to 1.2 tons of blast furnace water-quenched slag. At present, the blast furnace water-quenched slag accumulated in my country's slag yards has exceeded 100 million tons. Preparation of cement, concrete, and foam glass are the main methods for utilizing blast furnace water-quenched slag, but generally speaking, the comprehensive utilization rate of blast furnace water-quenched slag is insufficient and the added value of the product is low.
