example 1

[0010] Example 1: the various raw materials of the core layer are calculated by weight, and the alkali slag consumption is 60 parts, the fly ash is 20 parts, the glass powder is 15 parts, and the sawdust is 5 parts; the various raw materials of the shell layer are calculated by weight, and the glass powder content is 50 parts, 45 parts of clay, and 5 parts of sawdust. According to the above-mentioned weight ratio, each proportioning material is mixed evenly by a mixer. First add 30% of its weight of water to the dry material of the core layer to make pellets in the pelletizing tray, and then put the formed core layer balls into the pelletizing tray with the dry material of the shell layer by rolling the ball method, and start The ball forming tray is shaken for a long enough time so that the shell material is wrapped on the green body of the core layer to form a wrapping structure. The composition of the package structure is as follows: based on the weight of dry materials, 9...

[0011] Example 2: with the various raw materials of the core layer by weight, the alkali slag consumption is 60 parts, the fly ash is 15 parts, the glass powder is 20 parts, and the sawdust is 5 parts; the various raw materials of the shell layer are by weight, and the glass powder content is 45 parts, 50 parts of clay, and 5 parts of sawdust. According to the above-mentioned weight ratio, each proportioning material is mixed evenly by a mixer. During the molding process of the green body, first add 30% of its weight of water to the dry material of the core layer to make pellets in the pelletizing tray, and then put the formed core layer balls into the container filled with the dry material of the shell layer by rolling the ball. In the ball forming tray, start the ball forming tray to shake for a long enough time, so that the shell material is wrapped on the core layer green body to form a wrapped structure. The composition of the wrapping structure is as follows: based on d...

example 3

[0012] Example 3: By weight, the various raw materials of the core layer are 60 parts of alkali slag, 30 parts of fly ash, 10 parts of glass powder, and 0 parts of sawn wood; It is 45 parts, the clay consumption is 45 parts, and the sawdust consumption is 10 parts. According to the above-mentioned weight ratio, each proportioning material is mixed evenly by a mixer. In the process of forming the green body, the core layer is first formed, and 30% of its weight of water is added to the dry material of the core layer to make pellets in the pelletizing tray, and then the core layer balls are put into the shell with the ball rolling method. In the ball forming tray of the dry material, start the ball forming tray to shake for a long enough time, so that the shell material is wrapped on the core layer green body to form a wrapped structure. The composition of the package structure is as follows: based on dry material, the mass percentage of the core layer is 70 parts, and the mass...

Abstract

The invention discloses an alkaline residue porcelain granule which has a compound package structure. The alkaline residue porcelain granule comprises a porous core layer (2) and a shell layer having blind holes (1), wherein the porous core layer comprises alkaline residue, glass powder, coal ash and saw dust and the shell layer having blind holes comprises glass powder, clay and saw dust. A method for manufacturing the alkaline residue porcelain granule comprises the steps of: uniformly mixing the materials of the porous core layer and the shell layer having blind holes by a blender, adding water into the dry materials of the porous core layer to pelletize in a pelletizing pan in order to form the pellets of the core layer, placing the pellets into a balling pan which is filled with the dry materials of the shell layer, starting the balling pan, shaking for a sufficient time, packing the materials of the shell on the core layer by rolling in order to form the porcelain granule green-pressing having the package structure, drying the porcelain granule green-pressing at 105 DEG C, pre-burning the dried porcelain granule green-pressing, rising temperature and roasting, and then naturally cooling so as to finish the firing of the alkaline residue porcelain granule. The alkaline residue porcelain granule can efficiently prevent the chloride ion in the alkaline residue from dissociating and improve the application performance of the porcelain granule which uses the alkaline residue as raw materials in the concrete.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to alkali slag ceramsite with wrapped structure and a manufacturing method thereof. Background technique [0002] Alkali slag is a kind of waste slag discharged from ammonia-soda soda ash enterprises. Because of its high water content and a large amount of chloride, it has become a solid waste that is difficult to handle. For a long time, the alkali slag discharged from the alkali factory has occupied a large amount of cultivated land. It has caused great pollution to the environment. The comprehensive management of alkali slag has become a major scientific research topic in today's society. In the current situation of increasingly scarce natural resources, the research on using alkali slag to make building materials has become a hot spot. As a construction engineering material, alkali slag has been studied mainly in engineering soil and other aspects, and has been applied in engin...
