The raw clay waste is generated in the pieces conformation stage in the structural ceramic industry. Incorporation of raw clay waste is an alternative to make the structural ceramic sector more environmentally sustainable while reducing the consumption of clayey raw material. The Brazilian structural ceramic industry consumes 10.3 billion tons of clay per month. This work aims to study the technical feasibility of raw clay waste addition in clayey mass used in the structural ceramic production. Samples of raw clay waste and clay were tested for chemical, physical and mineralogical characterization. Specimens containing raw clay waste contents, varying from 10% to 90%, were produced and burned in a kiln at 850°C. The technological features evaluated were: water absorption, apparent porosity, apparent density, loss on ignition, firing shrinkage and mechanical strength. The results show that the addition of waste improves significantly the evaluated features.
