Example Embodiment

[0071] (1) Preparation of mixture: mix light-burned magnesia powder or a mixture of light-burned magnesia powder and quicklime, mineral admixtures, various aggregates and water measured in accordance with the ratio of raw materials and mix them to form a slurry . The equipment and processes used for raw material metering, mixing and stirring can adopt existing well-known equipment and processes.

[0072] (2) Mixture molding: The slab molding process can adopt the existing known sheet molding process, such as: extrusion molding process, group vertical mold casting molding process, etc. In the molding process, prefabricated fiber cloth can be manually placed into the mold or fiber injection machinery can be used to inject fiber chopped strands into the mold. The length of the chopped fiber strands should be controlled within 10-30mm. Before molding, a prefabricated rib skeleton must be placed in the mold.

[0073] (3) Pre-curing: The pre-curing of the board can adopt the same curin...

Abstract

The invention discloses a production process of building envelope products and belongs to the field of civil engineering. Light calcined magnesia power or mixture of light calcined magnesia power and quicklime is proportionally mixed with mineral admixtures such as granulated blast-furnace slag, coal ash, silica fume, red mud tailing powder and slag to obtain cementing material, the cementing material is mixed with aggregate and water into mixture used for producing building envelope material, and the building envelope material is finally hardened under CO2 environment into building envelope products such as building blocks, plates and tiles by means of mixing, forming, precuring and the like. The production process is low in production energy consumption, CO2 emitted from industrial waste residue and in industrial production is effectively utilized, and the building envelope products are new energy-saving environment-friendly products.

Description

technical field [0001] The invention belongs to the field of civil engineering, and specifically refers to a production process for producing building enclosure material products. Background technique [0002] Most of the building envelope materials (including bricks, blocks, plates, etc.) currently used in my country are made of cement as the cementitious material, adding various aggregates and mixing with water, and are made by forming, cutting, curing and other processes. The cementitious material cement used therein needs to be calcined at a high temperature during the production process, and the calcining temperature is 1450°C. Lightly burned magnesia powder and quicklime are cementitious materials obtained by calcination of magnesia (a mineral with magnesium carbonate as the main component) and limestone respectively. The calcination temperature is much lower than that of cement, 750°C and 900°C respectively. , so its production energy consumption is much lower than t...
