Накратко на български

Зеленият геополимерен бетон се създава изцяло от отпадъци от строителство и разрушаване за производство на разглобяеми структурни компоненти. Това помага за намаляване на вредните емисии от цимента и ограничава количеството отпадъци, които се изхвърлят в сметищата.

Construction and Demolition Waste-based “Green” Demountable Structural Components

Traditional concrete is the main building block of our infrastructure and it uses Portland cement (PC) as the main binding agent, production of which is fast increasing globally and responsible for about 7-10% total man-made annual anthropogenic CO2 emissions significantly contributing to global warming. Negative impacts of PC manufacturing are coupled with the quarrying of natural aggregates. Concrete also constitutes more than half of the 800 million tons of construction and demolition waste (CDW) generated each year, which is the largest waste stream in almost all countries. CDW industry is recognized one of the main sectors contributing to the global solid waste production, constituting 30-40% of total urban waste and its landfilling is responsible for about 35% of the deposition area worldwide. On the other hand, reinforced concrete structures lack of longevity due to their high deterioration tendency under simultaneous mechanical and environmental effects, which leads to increased needs for new demolition and reconstruction activities furthering the quantity of CDW generated and raw materials for the manufacturing of new construction materials. This is also exacerbated by catastrophic events such as earthquakes. In an effort to tackle the issues related to generation of massive amounts of CDW as well as traditional concrete, CodeDEMO project proposes a new paradigm of manufacturing construction materials and demountable structural components by using resources coming entirely from CDW, with the following main objectives: (i) the development of structural geopolymeric green concrete mixtures with both binder and aggregate phases based on CDW and (ii) the use of green structural concretes in the design and production of pre-fabricated demountable structural components for a more resource- and eco-efficient designs for building circularity.

Цел на проекта

Generation of high volumes of construction and demolition waste (CDW) is seriously problematic from environmental, economic and societal perspectives. Furthermore, CDW is generally managed by the proposition of low-tech recycling applications which are costly, energy-inefficient and unsustainable. Within the scope of the current project, a new construction paradigm composed of pre-fabricated large-scale elements produced with 100% recycled “green” materials out of CDW that can be easily assembled/disassembled according to a cradle-to-cradle design approach is proposed. Current project will not only propose completely “green” solutions on materials’ basis but also on structural basis by developing geopolymeric (cement-free) concrete mixtures, ingredients of which will be obtained completely from CDW and large-scale structural components that will be easily demountable without creating extra waste and consuming too much energy. The action will also develop and enhance the research fellow’s transferable skills necessary for thriving his career in a flourishing area that underpins innovative technological development across a range of diverse disciplines and will make a marked impact on know-how exchange of interdisciplinary research expertise, breaking the common trend in construction industry and strengthening the ties among researchers/engineers who work on construction materials and structural aspects.
