" subtle concrete structures" . "According to the results of expert's analysis, the concrete production represents 7% of all CO2 emissions. The effort to reduce those harmful impacts leads the experts worldwide to search for the possibilities of savings in concrete consumption resulting in decrease of emissions. The results of such efforts lead to the change of silicate composites design, such as self compacting concrete (SCC), high strength concrete (HSC), high performance concrete (HPC) and ultra high performance concrete (UHPC). Proposed project is focused on research of new UHPC composites reinforced with textile meshes and polymer fibres. It is assumed that these types of fibres enable the design of ultra thin structural concrete elements. The aim of the research is theoretical and experimental verification of UHPC matrix in combination with non conventional reinforcement and verification of structural behaviour and environmental parameters of ultra thin elements from optimized silicate composite designed from local materials."@en .
