Abstract

The invention discloses a tuff and tuff lava sintered brick and a preparation method thereof. The tuff and tuff lava are used as main materials combined with the weathered soils of the tuff and the tuff lava, or silts from rivers, lakes and seas or building waste soils or clays as adhesives, or slag or coal gangues or fly ashes or coals are also used as internal fuels. The tuff and tuff lava sintered bricks are prepared by the procedures of crushing, stirring, blank forming, drying and roasting, etc. The preparation method is characterized by utilizing industrial wastes, environmental protection, saving soil and energy, improving the compressive strength and thermal insulation performance of bricks, and the like, and the tuff and tuff lava sintered bricks conform to the national standards of sintering porous bricks, hollow bricks and road bricks. The tuff and tuff lava sintered brick has the advantages of high strength, heat preservation, convenience for preparation and construction, and the like, and is another new product replacing clay brick after the nation prohibits clay brick usage.

Description

technical field [0001] The invention relates to a building material, in particular to a tuff and tuff lava sintered brick produced by using tuff and tuff lava as raw materials and a production method thereof. Background technique [0002] Brick is a commonly used building material, and bricks are usually divided into fired bricks and non-fired bricks. All bricks made by roasting are called sintered bricks, such as clay sintered bricks, sintered hollow bricks, etc. Clay sintered bricks are mainly made of clay, which is made by batching, shaping, drying, and high-temperature roasting; cement and lime are used as raw materials. The bricks made of raw materials are non-fired bricks, such as lime sand bricks, cement porous bricks, etc. Due to the use of clay as a material for traditional clay fired bricks, a large amount of land has been destroyed. In order to protect cultivated land, the state has issued repeated orders to prohibit and use clay fired bricks. Therefore, the prod...
