Abstract
The invention provides a process for producing bricks by using saponification residual slag. The process comprises processes of pretreatment of raw materials, batching, mixing and humidifying of materials and forming of adobe. During batching, materials comprise, by weight percentage, 20%-35% of the saponification residual slag, 15%-30% of aggregate and 35%-65% of fly ash and the batching is conducted through a batching machine. By the aid of the process, during steam curing process, calcium hydroxide and silicon dioxide and aluminium oxide in the fly ash are subjected to chemical reaction, hydrated calcium silicate and hydrated calcium aluminate are produced, a layer of hydration products is formed on surfaces of the fly ash and other mixing materials, so that the fly ash and other mixing materials are cemented together, a wall material with certain physical and mechanical properties is formed, and the strength of bricks is more than mu 10. The process is simple, a lot of residual slag can be processed, devices are simple, clay bricks can be replaced, land resources are saved, no environment pollution exists, wastewater cannot be produced and secondary solid waste cannot be produced.
Description
Technical field
