Objective
Objectives and content
Cement and concrete manufacturers have a strong need for sufficient supply with quality raw materials at acceptable expenses. The supply from quarries and gravel pits is running short, due to decreasing resources and environmental restrictions. In addition, the generation of demolition wastes is increasing with dramatic growth rates, at the end of the century at least 175 M. tons annually. European Directives on waste dumping and landfills are very strict, the dumping costs are increasing all over Europe. So the construction sector has an imperative need for reusing building rubble. Until now it is limited only to subordinate purposes though its potential performance is much higher.
With respect to total building rubble recycling, the project considers as well the coarse portions for producing high quality concrete as the reuse of fines <4 mm. i.e. about 40% of all demolition waste, for cement manufacturing. There is no evidence that studies for this purpose have been developed in Europe or elsewhere.
The first aim of the project is to develop appropriate technologies for manufacturing high quality cement and concrete, using representative demolition waste in different countries with a variability of composition, contamination and material properties:
- Research on mechanical, physical and chemical properties (e.g. strength, creep and shrinkage, leaching tests) with emphasis on durability behaviour (e.g. freeze/thaw resistance) will be carried out to prove the applicability and limiting conditions.
-Prenormative requirements and guidelines and furthermore design specifications for recycling will be deduced from the results.
Achievements of this project will bring solutions to all aspects of the product life-cycle: Raw material - Processing - Manufacturing - User - Recycling.
The final result will be a definitive design and specification manual for the reuse of demolition waste for high quality building products. This will be demonstrated both by the production of cement meeting the EN requirements and by various concretes with high performance, both produced with building rubble replacing natural raw materials.
Main expected benefits are:
-Costs reduction of: raw materials, process energy, transport and quarries exploitation,
-Reduction of environmental impact: rational use of raw materials, crucial reduction of waste deposition, reduction of CO2, heavy metals and other pollutant emissions.
