Original Abstract

The article deals with self-compacting concrete mix-design with light-weight aggregate Liapor for strength class LC 25/28, D 1.6 and mix-design with light-weight aggregate Liapor combined with natural aggregate for class LC 40/44, D 1.8. These mix-designs were tested with synthetic fibres Chryso Fibre S50 in the amount of 1, 4 and 8 kg/m3 and steel fibres 20 mm in the amount of 25 kg/m3. Rheological properties were experimentally tested by means of Slump test, Orimet, J-Ring and L-Box immediately after mixing and at time intervals of 60 and 90 minutes after mixing. Volumetric changes including development of temperature of fresh concrete were measured for 7 days from the time of placing. Physico-mechanical properties of hardened concrete were observed - compressive strength after 7 and 28 days, tensile bending strength after 28 days, static and dynamic elastic modules, frost resistance, surface resistance to water and defrosting chemicals.
