Abstract

The invention discloses a non-sintered slag soil wall body block and specifically relates to a non-sintered brick or building block prepared from industrial waste slag or engineering slag soil and a preparation process thereof. The non-sintered wall body block disclosed by the invention mainly comprises the following main raw materials in parts by dry weight: 55-85 parts by weight of industrial waste slag or engineering slag soil, 5-15 parts by weight of cementing material, 0-12 parts by weight of fine aggregate and 0.05-0.1 part by weight of modifying additive. The non-sintered slag soil wall body block disclosed by the invention has wide raw material sources, fully utilizes the extensive and large-quantity industrial waste slag and engineering slag soil, turns wastes into treasure, saves land resources and protects cultivated land. The produced non-sintered slag soil wall body block has the advantages of high compressive strength, good resistance to seepage, freezing and thawing, heat preservation, heat insulation and environmental friendliness. The finished product rate of a product is more than 99%, and the product is suitable for industrial batch production.

Description

technical field [0001] The invention relates to a non-sintered slag wall body block material, in particular to a non-sintered brick or building block made from industrial waste slag or engineering slag and a preparation process thereof. Background technique [0002] Industrial waste is solid waste discharged from industrial production, including coal gangue, shale, fly ash, etc. Engineering slag is a large amount of underground or underground engineering soil excavated during engineering construction, and a large amount of solid waste such as waste concrete, waste bricks and tiles, etc. generated during urbanization and demolition. [0003] The stacking of these two types of muck not only wastes a lot of resources, but also causes a lot of waste of land and damages the natural environment. How to clean up and dispose of these piled industrial wastes or engineering slags has become a common concern of the society. Recycling these slags efficiently and according to local cond...
