Example Embodiment

[0030] Example 1

[0031] A sintered hollow brick with silt waste stone powder, which is made of the following components by weight: 40% silt, 25% waste stone powder, 20% coal gangue, 0.5% vegetable straw powder, 3% modified ceramic powder, 4% sea mud, non 1.5% crystalline quartz particles, 1.5% sodium fluorosilicate, 1% kyanite, 0.5% polyvinyl alcohol resin, 1.5% sepiolite, 1.5% shell;

[0032] The processing method of the above hollow brick is as follows:

[0033] (1) Crushing: Use a fine crushing jaw crusher, hammer crushing or fine crushing to crush the raw materials. The diameter of the raw material particles: 7% greater than 1.5mm, 18% of 1.5-0.9mm, 0.9-0.3mm 51%, 24% less than 0.3mm;

[0034] (2) Mixing and stirring: Add appropriate amount of water to the crushed raw materials and stir evenly, the moisture content of the mixture after stirring treatment is 12.5%; (Note: The above data is based on each 500g as a sample standard).

[0035] (3) Aging: input the stirred raw materia...

Abstract

Provided is a sintered hollow brick prepared from silt and dumped stone powder.The sintered hollow brick is prepared from, by weight, 40% of silt, 25% of dumped stone powder, 20% of coal gangue, 0.5% of plant straw powder, 3% of modified ceramic powder, 4% of sea mud, 1.5% of amorphous quartz particles, 1.5% of sodium fluosilicate, 1% of kyanite, 0.5% of polyvinyl alcohol resin, 1.5% of sepiolite and 1.5% of shells.According to the sintered hollow brick prepared from the silt and the dumped stone powder, raw material consumption can be reduced, and it is guaranteed that the inherent quality of a formed green body is stable; the molding pressure is large, and the green body strength is high; combustion is achieved by means of the calorific value of the coal gangue itself, energy is saved, and pollution is reduced; the produced coal gangue hollow brick reduces the structure weight of a building, improves the building function and has good heat preservation and sound insulation properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a hollow brick sintered with sludge waste stone powder. Background technique [0002] Coal gangue is one of the largest industrial solid wastes in China. Moreover, the annual discharge of coal gangue is equivalent to about 10% of the coal production in that year. The annual emission rate will be greater than 160 million tons. Stacking coal gangue not only takes up a lot of land, but also pollutes the environment and affects people's life and health. In addition, the spontaneous combustion of coal gangue can release a variety of harmful gases, etc., and at the same time it is accompanied by a large amount of smoke and dust and has the risk of explosion. Therefore, the spontaneous combustion of coal gangue has different degrees of impact on the surrounding atmospheric environment, human health, and animal and plant growth. Fly ash is one of the largest industrial was...
