Description
Clay bricks can be used to prepare refractory bricks; this dataset includes primary raw materials, auxiliary materials, energy inputs, atmospheric emissions, and waste generated during the production process. Infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The production process of clay bricks involves crushing, batching, mixing and molding, drying, firing, inspection, and packaging.
Activity Description
The production activities of clay bricks include processes such as crushing, batching, mixing and forming, drying, firing, inspection, and packaging.
Process Description
The Al2O3 content in fireclay bricks is generally above 40%, with Fe2O3 content less than 2.0–2.5%. The mix composition typically consists of 65–85% calcined grog and 35–15% bonding clay. The finely ground bonding clay and milled calcined grog are blended, then combined with coarse grog to form a semi-dry mix, which is pressed at high pressure and fired at approximately 1400 °C, resulting in favorable properties. Fireclay bricks exhibit weak acidity at high temperatures and have relatively poor resistance to alkali slag corrosion. Fireclay bricks are made from readily available materials, offering low cost, high durability, and advantages such as fire resistance, thermal insulation, sound insulation, and moisture absorption.
