Development of New Eco-Efficient Cement-Based Construction Materials and Recycled Fine Aggregates and EPS from CDW

Background:

This research paper presents the results of the characterization and adaptation of the construction product developed by the Experimental Centre of Production of the Faculty of Architecture, Design and Urbanism of the University of Buenos Aires, Argentina (CEP FADU UBA) for Spanish regulations. Additionally, it shows the study of the industrialization of its manufacturing process in Spain. The product consists of a cement-based compound that includes recycled fine ceramic aggregates and EPS from rehabilitation works.

Objectives:

The aim of this research work is to propose a new eco-efficient construction product adapted to Spanish and European regulations in order to minimize the environmental impact of the construction activity, improve energy efficiency and reduce construction costs. Furthermore, it is presented as a solution to the problem that construction and demolition waste management represents.

Method and Results:

Samples have been tested to the water absorption and compression resistance tests according to UNE standards. These parameters serve to delimit its use in new sustainable constructive solutions for the design of zero energy consumption buildings (nZEB).

Conclusion:

Results show that it is possible to obtain certain samples that include recycled ceramic aggregates and EPS which present good response to the mechanical and water absorption tests. In addition, it is obtained that industrializing this product in Spain is complex due to the current waste management system.
