Innovative geopolymeric ingredients for mortars and structural insulation panels with tailored properties

Main goal of this project is the development of mortars based on innovative geopolymeric ingredients which by adding weee powders it can be obtain new construction materials with good flame retardant, thermal, acoustic, electromagnetic proprieties.

The production of hazardous waste materials from industrial processes has cause major concern on the environment due to their intractable, harmful and costly disposal methods. Therefore, a new type of geopolymer composites can be synthesized from different industrial waste material including the waste from recycled Electrical and Electronic Equipment (WEEE). As the market continues to expand and innovation cycles become even shorter, the replacement of equipment accelerates, making EEE a fast-growing source of waste. While Directive 2002/95/EC has contributed effectively to reducing hazardous substances contained in new EEE, hazardous substances such as mercury, cadmium, lead, hexavalent chromium and polychlorinated biphenyls (PCBs) and ozone-depleting substances will still be present in WEEE for many years. The content of hazardous components in EEE is a major concern during the waste management phase, and recycling of WEEE is not undertaken to a sufficient extent. A lack of recycling results in the loss of valuable resources. The purpose of DIRECTIVE 2012/19/EU is to contribute to sustainable production and consumption by, as a first priority, the prevention of WEEE and, in addition, by the re-use, recycling and other forms of recovery of such wastes so as to reduce the disposal of waste and to contribute to the efficient use of resources and the retrieval of valuable secondary raw materials. From 2016, the minimum collection rate shall be 45 % calculated on the basis of the total weight of WEEE collected. Member States shall ensure that the volume of WEEE collected evolves gradually during the period from 2016 to 2019. From 2019, the minimum collection rate to be achieved annually shall be 65 % of the average weight of EEE placed on the market in the three preceding years in the Member State concerned, or alternatively 85 % of WEEE generated on the territory of that Member State. Until 31 December 2015, a rate of separate collection of at least 4 kilograms on average per inhabitant per year of WEEE from private households or the same amount of weight of WEEE as was collected in that Member State on average in the three preceding years, whichever is greater, shall continue to apply. By derogation, Bulgaria, the Czech Republic, Latvia, Lithuania, Hungary, Malta, Poland, Romania, Slovenia and Slovakia may, because of their lack of the necessary infrastructure and their low level of EEE consumption, decide to achieve, from 14 August 2016, a collection rate that is lower than 45 % but higher than 40 % of the average weight of EEE placed on the market in the three preceding years; and the percent of collection rate corresponding to period after 2016 shall reached not later than 14 August 2021. Utilization of waste materials and byproducts is a partial solution to environmental and ecological problems. Use of these materials not only helps in getting them utilized in cement, concrete and other construction materials, it helps in reducing the cost of cement and concrete manufacturing, but also has numerous indirect benefits such as reduction in landfill cost, saving in energy, and protecting the environment from possible pollution effects. WEEE consists of discarded old computers, TVs, refrigerators, radios – basically any electrical or electronic appliance that has reached its end of life. Efforts have been made in the concrete industry to use non biodegradable components of WEEE as a partial replacement of the coarse or fine aggregates. The possible utilization of WEEE particles as coarse aggregates in concrete can vary between 0 % to 30%. Recent studies have shown that reuse of very finely grounded WEEE powder in concrete has economical and technical advantages for solving the disposal of large amount of WEEE, reuse in complete industry may be the most feasible application. WEEE particles can be used as coarse aggregate, fine aggregate, fine filler in concrete depending on its chemical composition and particle size. WEEE sources in the form of loosely discarded , surplus, obsolete ,broken, electrical or electronic devices will been collected, crushed and ground to the particle size. Compressive strength, Tensile strength and Flexural strength of Concrete with and without WEEE as aggregates will be made at varying mix design proportion, different curing age and different concentration of alkaline activator will be studied. It is to investigate the optimum synthesis condition based on the compressive strength of the specimen. Prior to the concreting work, few sets of characterization tests specifically X-Ray Fluorescence Analysis (XRF), Sieve Analysis test and Laser Diffraction Particle Sizing test on the WLP will be carried out for selection of sample with optimum condition for geopolymer concrete production.
