| The European Union has identified the flow of construction and demolition waste (CDW) as a priority waste stream. In 2012 more than 2.5 million tons were generated, of which almost 33% was derived from building sector. Also according to the data sheet "Construction and Demolition Waste" published by the Ministry of Environment, in Spain 54% of the waste generated wastes correspond to ceramics, which are referred to in the European Waste List (MAM Order / 304/2002) as "Non-Hazardous Industrial Waste (RINP)". Because of this situation, the Spanish government has created several rules focused on minimizing the environmental impact caused by the construction industry and, in particular, a specific standard for the proper management of the CDW (Royal Decree 105/2008), which aims to promote their reduction and avoid landfilling, promoting as well the correct waste management to turn them into resources and save raw materials. Therefore CEDEX has created a guide CDW reuse as raw material for the manufacture of mortar, concrete, brick and lightweight aggregate. However, no manual establishes strategies for recycling wastes in gypsum composites. For all this, the aim of this study is to analyze the feasibility of incorporating ceramic brick waste from new construction and ceramic tile waste from demolition in a plaster matrix, through a pilot scheme carried out in laboratory and ensuring compliance with regulations. The purpose is that construction agents can find various options for reuse of construction waste generated. Results show that it is possible to incorporate up to a 50% of ceramic waste over the weight of gypsum without changing its basic properties. With this addition it can be obtained a reducing in compressive strength only by 4%, a 6% increase in the surface hardness and a 25% reduction of capillary water absorption. All these results will be exposed in a waste reusing database, which will be developed by the Polytechnic University of Madrid to help promoting the reduction of environmental impact caused by the construction sector. | |
