Environmentally effective waffle floor structures from fibre concrete

Popis výsledku v původním jazyce

Development of sustainable material effective structure is based on the effort to reduce primary non-renewable material consumption. Utilization of fibre concrete creates the conditions for the dimension optimization, leading to the savings in raw materials and thus to the more favourable environmental characteristics of realized structures. The aim of the research is to verify the potential design of slender waffle floor structures with minimized thickness of upper slab (25 to 30 mm). Test specimens inthe form of representative segment of waffle floor slab were made from two different mixtures: HPC with 25 mm long steel fibres and UHPC with 13 mm long steel fibres. Ribs were reinforced by steel rods, upper deck only by steel fibres. The specimens were tested by the combination of torsion and bending. The environmental evaluation of samples proved that by the shape and material optimization up to 70% of material can be saved.
