Baking-free building block produced by utilizing nonmetallic waste slag and preparation method

Abstract

The invention discloses a baking-free building block produced by utilizing nonmetallic waste slag and a preparation method. The baking-free building block is produced by magnesium oxide, magnesium chloride, perlite, silicon-calcium powder and waste slag according to a certain proportion. The preparation method comprises the following steps: 1, waste slag with abundant resources is selected under specific conditions, and materials are prepared according to a state requirement; 2, integrated feeding is carried out according to the mixture ratio of a formulation; 3, the mixture is uniformly stirred by a stirrer; 4, compression moulding forming is carried out by a special brick making machine; 5, prehardening conservation is carried out by a supporting plate; 6, the supporting plate is removed, and natural curing conservation is carried out by stacking; 7, classification warehousing is carried out after detection; and 8, the product is sold and used. The invention has reasonable formulation, simple operation and low cost, and the building block is energy-saving and environmental-friendly and does not need sintering and steam pressure maintenance.

Description

technical field [0001] The present invention relates to a technical field of building materials, more specifically to a production of unfired blocks by using non-metallic waste slag, and also relates to a preparation method for producing unfired blocks by using non-metallic waste slag, which is applicable to various Environmentally friendly and energy-saving buildings. Background technique [0002] Qin bricks and Han tiles have been used for more than 5,000 years in the history of Chinese architecture. The production of sintered clay bricks not only destroys cultivated land, but also consumes a lot of energy. In fact, by the end of 2010, the use of solid clay bricks will be completely banned in all cities and towns across the country. [0003] Without red bricks, what to use to build walls?

[0003] Without red bricks, what to use to build walls? In recent years, various products such as autoclaved lime sand bricks, coal gangue sintered bricks, and concrete hollow blocks have appeared on the market. However, after construction and use, it has been proved that these products are either uneconomical or have defects in performance.
