Abstract

The invention relates to the technical field of sintered brick production, in particular to a coal gangue sintered brick and a production process thereof. The coal gangue sintered brick is prepared from the following raw materials in parts by weight; 70- 90 parts of coal gangue, 10-15 parts of fly ash, 6-10 parts of gypsum, 4-6 parts of coal cinder, 5-8 parts of diatomite, 6-10 parts of hollow glass beads, 3-6 parts of furnace slag, 12-18 parts of sludge, 10-15 parts of sludge, 9-14 parts of construction waste soil, 16-21 parts of shale, 4-8 parts of a functional additive, 2.8-4.2 parts of a mineralizing agent, 2.3-3.5 parts of a fluxing agent, 2.0-2.6 parts of a flocculation agent and 1.8-2.5 parts of a cementing agent. The coal gangue sintered brick prepared by the process not only can reduce the waste of resources, but also realizes the purpose of changing waste into valuables, and accords with the concept of green development at present; furthermore, the coal gangue sintered brickproduced by the production process not only has good antibacterial performance, but also can adsorb harmful gases such as indoor formaldehyde or benzene; in addition, the strength and the plasticity of the coal gangue sintered brick are improved to a great extent and the quality of the coal gangue sintered brick is improved.

Description

technical field [0001] The invention relates to the technical field of sintered brick production, in particular to a coal gangue sintered brick and its production process. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Coal gangue is a rock mixed with organic and inorganic compounds co-deposited with coal during the coal formation process, usually in a thin layer and in the coal seam or at the top or bottom of the coal seam. Coal gangue is divided into clay rocks, sandstone rocks, carbonates, and aluminum rocks according to the main mineral content. According to the source and final state, coal gangue can be divided into three categories: excavation gangue, coal preparation gangue and natural gangue. [0003] Coal gangue is discarded, occupying a large area of...
