Manuscript Topics
The carbon dioxide emissions are caused by many activities including construction that, due to cement production alone, contributes with more than 6% of this value. Concrete is the most used construction material in the world, with an estimated yearly production of 2.35 Mton. The main reason for the high environmental impact associated with concrete production is related to the use of Portland cement. In order to produce a single ton of cement it is necessary to use 125 kW of electricity and to emit to the atmosphere about 800 kg of CO2. On the other hand, the use of natural aggregates is another serious environmental impact caused by concrete production, which can be tackled by the use of recycled aggregates. This solution also allows reducing the amount of waste discarded illegally or placed in landfills.
This special issue focuses on the development of sustainable cementitious composites, either by the use of recycled aggregates or by the use of sustainable binders produced from recycled materials or other industrial by-products.
Research articles concerning the experimental characterization of sustainable concrete (SC), the development and implementation of analytical methods or numerical models applied to the characterization of SC and the life cycle assessment or life cycle cost analysis of SC are particularly encouraged.
