Slickens baked brick and production method thereof

Abstract

The invention relates to a braked brick, specifically a braked brick prepared from slickens and a preparation process thereof. The sintering material of the slickens baked brisk, in terms of oven dry weight, comprises the following components in part by weight: 35 to 45 parts of slickens by weight, 30 to 45 parts of coal gangue or coal cinder by weight, 10 to 25 parts of engineering dregs or shale by weight, 5 to 10 parts of clinker by weight and 3 to 8 parts of fine sawdust or rice husks by weight. The material source of slickens baked brisk is extensive, so that the waste slickens is recycled to save the land resources and protect the cultivated land, thus the large-surface yield slickens waste which easily generates raise dust is sufficiently used for changing waste into valuable and purifying the environment. The acquired slickens baked brisk is thermally insulated and heat-insulated, shock and pressure resistant, free of decrustation and distortion, and difficult to break and burst; the yield can be more than 99%, thus the slickens baked brick is suitable for the large-scale industrial production.

Description

technical field [0001] The invention relates to a sintered brick, in particular to a sintered brick made of stone mud and a preparation process thereof. Background technique [0002] Stone mud is the waste produced by stone processing. It is a mixture of stone powder and water. Once the water in the stone mud is lost, the stone powder is easily blown up by the wind to generate dust, which will cause great pollution to the surrounding environment; , cannot be used as building materials like sand, and some are even discharged directly into the river, causing the river to be turbid. [0003] The stacking of rock mud not only wastes a lot of resources, but also produces serious secondary pollution. When the wind blows, it is no less than a sandstorm. How to clean up and dispose of piled rock mud has become a common concern of all sectors of society. How to effectively, adapt measures to local conditions, and recycle rock mud is of great significance to resource recycling and to...

AI Technical Summary

Problems solved by technology

However, due to the looseness of the stone mud itself, it is easy to crack or burst when making sintered bricks, so sintering is difficult. In the prior art, a large amount of binder, such as silt, needs to be added when using waste rock powder to prepare sintered bricks. or cement, otherwise it cannot meet the requirements of industrialization
