Within a current BRITE/EURAM project, investigations were carried out on the use of processed building rubble and its effects on concrete properties. The material was produced using different processing plants. Though the main constituent was crushed concrete, the proportion of other materials was also considered. The amount of impurities, such as wood, plastics, paper, etc., within the selected samples were negligible. Sulphate and chloride levels within the selected samples were below harmless levels. It has been recognised that the qualitative assessment of the average composition and uniformity of the material can be made by thermogravimetric analysis, therefore, such examinations were considered. The particle density and water absorption, which are the critical characteristics to produce concrete with desirable properties were studied. Other properties which can provide additional information but do not directly influence the concrete properties were also examined. It was concluded that the results of this work can produce useful information for practical guidelines for the use of materials.
