Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] A coal gangue shale sintered hollow brick, made of the following components by weight: 10% industrial waste soil, 50% waste stone powder, 25% coal gangue, 3% potassium phosphotungstate, 1.5% cellulose, 1.5% activated carbon, Zirconium silicate 1.5%, asbestos powder 1.5%, sepiolite powder 1.5%, tourmaline powder 1.5%, modified ceramic powder 3%;

[0025] The processing method of above-mentioned hollow brick is as follows:

[0026] (1) Crushing: The raw materials are crushed by fine crushing jaw crusher, hammer crushing or fine crushing roller machine. The diameter of raw material particles: 9% greater than 1.5mm, 24% of 1.5-0.9mm, 0.9-0.3mm 46%, 21% less than 0.3mm;

[0027] (2) Mixing and stirring: add an appropriate amount of water to th...

Abstract

The invention provides a gangue shale fired hollow brick. The gangue shale fired hollow brick is characterized by being prepared from the following components by weight: 10% of industrial spent clay, 50% of waste stone powder, 25% of gangue, 3% of potassium phosphotungstate, 1.5% of cellulose, 1.5% of activated carbon, 1.5% of zirconium silicate, 1.5% of asbestos powder, 1.5% of sepiolite powder, 1.5% of tourmaline powder and 3% of modified ceramic powder. The gangue shale fired hollow brick has the beneficial effects that raw materials can be saved and the stability of the inherent quality of the formed green body is ensured; the briquetting pressure is high and the strength of the green body is high; the energy is saved and pollution is reduced by firing the brick by utilizing the calorific value of gangue; the gangue hollow brick produced by the process has the beneficial effects of reducing the dead weights of building structures and improving the building functions and has good heat and sound insulation properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a coal gangue shale sintered hollow brick. 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 wastes in my cou...
