Abstract
The invention relates to a method for preparing lightweight ceramic building blocks by the use of building garbage. Building garbage is used as the main raw material; that is to say, inorganic non-metallic materials such as waste residue soils, crushed bricks, crushed tiles, crushed ceramics, cullet, concrete blocks and the like are used as the main raw materials to prepare the lightweight ceramic building blocks. The process flow provided by the invention comprises the following steps of: collection of building garbage; crushing, ball-milling and sieving; preparation of a mixture; uniform mixing; granulation; die-filling; sintering; cutting and finishing to obtain a finished product. According to the invention, the application range of the raw materials of the lightweight ceramic building blocks is widened, opening a novel approach for digesting building garbage. Tests show that the amount range of building garbage is less than or equal to 75% and larger than or equal to 20%.
