This decade has provided ample evidence that the ceramic industry needs to minimise the impact of its operations on environment. The amount of refuse is estimated to be over 100 000 tons per year in Portugal. On the European level it is estimated to be around than a million ton annually. Hence, the reutilization of this refuse is of great environmental interest. This research project deals with an industrial application of this refuse that can substitute raw material and partially energy intensive materials in construction. Preliminary studies performed on ceramic refuse indicated that these materials have a high content of amorphous metakaolinite. The finely grained ceramic wastes showed pozzolanic properties, i.e. reacted with lime at ordinary temperature producing extra cementitious materials. Based on the results obtained so far this research project proposes to study the application of crushed or grained ceramic wastes in concrete industry. The project prime aims it's to improve the concrete performance with substitution of it constituents by these by products. Besides, this substitution will reduce the final costs of concrete. In this way it will be possible to recycle the wastes from the ceramic industry, saving at the same time the raw materials and energy used for production of cement and aggregates.
