Název v původním jazyce

Ultra-high strength steel fibre reinforced concrete

Popis výsledku v původním jazyce

Ultra-high strength steel fibre reinforced concrete with cement matrix contains silica cement, basalt aggregate, steel fibres, admixtures and additives. The dosage of admixtures is given by the results of the porosity tests of basalt aggregate and steelfibres mixture. The admixtures are dosed so that the required workability is reached; according to real application. There is 600 to 1000 kg/m3 of silica cement in cement matrix, basalt aggregate has three sieve sizes, namely 0-4, 4-8 and 8-16, the totaldose of basalt aggregate is in the range 1500 and 2000 kg/m3. Ratio of sieve sizes is determined by granulometry and mineralogical composition of particular source of basalt aggregate. Water/cement ratio ranges between 0.16 and 0.25. Two types of steelfibres are evenly distributed in the volume of hardened steel fibre reinforced concrete. The first type of fibres has rectangular section with width ranging between 0.2 and 0.5 mm, height between 1.5 and 2.0 mm and length between 25 and 3
