Problems solved by technology

Most of the waste ceramics are disposed of by landfill, which has serious pollution to the environment.
At present, building blocks are made by introducing ceramic materials as raw materials for concrete blocks to improve the resource recycling rate of ceramic materials, but the existing building blocks made of ceramic materials still need to add a large amount of cement and other additives. Improve the performance of blocks, therefore, the existing building blocks made of ceramics have not been significantly changed in terms of production cost and performance

Abstract

The invention relates to the technical field of building materials, and particularly discloses a ceramic building block and a preparation method thereof. The ceramic building block comprises the following components in parts by mass: 45-65 parts of ceramic coarse aggregate, 45-58 parts of ceramic fine aggregate, 20-25 parts of ground ceramic powder, 20-25 parts of sodium silicate and 8-12 parts of water. According to the ceramic building block provided by the invention, ceramic is used as a main raw material, under the condition that traditional components such as cement, sand and lime are not added, only three ceramic raw materials with different particle sizes and proportions are compatible, and a conventional curing process is performed under the action of sodium silicate, so that relatively high use strength can be achieved, and addition of cement is omitted; and the manufacturing cost of the building block is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a ceramic block and a preparation method thereof. Background technique [0002] In recent years, most of the block materials used in my country's housing construction projects are autoclaved aerated concrete blocks. Compared with sintered clay bricks, autoclaved aerated blocks have light weight, With excellent properties such as thermal insulation, sound absorption and good processability, it is gradually becoming a popular material in the construction industry. The existing autoclaved aerated blocks are made of cement, sand, lime and fly ash as main raw materials. Although they show many excellent properties as building masonry materials, the acquisition of siliceous materials and calcareous materials The method often has a negative impact on the ecological environment, and the extensive use of cement also increases the production cost of autoclaved aerated blocks to ...
