PRELIMINARY RESULTS OF THE RESEARCH PROJECT ENTITLED 'DEVELOPMENT OF NEW ECO-MATERIALS AND SUSTAINABLE CONSTRUCTIVE SOLUTIONS BASED ON THE USE OF WASTE AND RENEWABLE RAW MATERIALS IN BUILDING ACOUSTICS'

摘要

The new European regulations about building products of the European Union Standard number 305/2011 of European Parliament, are about the sustainable use of natural resources. In 2014, a research project financially supported by the Spanish government (with reference BIA2013-41537R), has started to develop sustainable materials, which is entitled "Development of new eco-materials and sustainable constructive solutions based on the use of waste and renewable raw materials in building acoustics". Different materials are tested to verify if they accomplish the new established conditions. The research project is involved in the challenge about climate change and energy efficiency in the use of materials proposed by the European Union in the frame of Horizon 2020, focused on the item about utilization of raw materials. The first results are presented with different types of materials: recycled foam, animal wools, recycled wools, nanofibers and nanopapers, mixed with composites. The results are about sound absorption coefficient, flow resistivity, dynamic stiffness and some tests for acoustic isolation.
