CSA Sub-materials for Manufacturing CSA Cement Using Waste By product

摘要

The present invention relates to an auxiliary material for manufacturing CSA cement using waste by-products, and more particularly, as a waste sludge containing some or all of the components of CaO-Al2O3-SiO2-SO3-Fe2O3, which is a major component of CSA cement, silicon wafer sludge, desulfurization Waste by-products that are discarded while using fly ash and dyeing wastewater sludge, and by mixing one or more of waste lime and iron-making sludge as a moisture content control material and providing it as an auxiliary material for mixing with lime, the main raw material of CSA cement. In addition to solving environmental problems by the use of CSA, it is characterized by reducing the cost of raw materials for the production of CSA cement, and in particular, the cost of raw materials can be reduced because expensive Al-based raw materials can be used inexpensively and stably.
