Characteristics of SFRC with Fibres Dramix 4D and 5D Produced by Bekaert

Popis výsledku v původním jazyce

The paper presents load-deflection diagrams measured in flexural tests of prisms performed to compare standard fibres 3D and fibres 4D and 5D. Fibre Dramix 4D and 5D differ from the standard fibres 3D by hooked ends that should provide better anchoring of fibres in the fibre concrete structure. Enhanced fibre concrete characteristics are exhibited by the BEKAERT firm in case of use of 4D and 5D fibres. The beneficial behaviour of SFRC with 4D and 5D fibres was evaluated with help of four-point flexuraltests according to Czech Prestandard ČSN P 73 2452 ?Zkoušení ztvrdlého drátkobetonu? (Testing of hardened Steel Fibre Reinforced Concrete). Four-point tests of prism specimens 150/150/700 mm are strongly recommended as they provide information on SFRC properties with respect to homogeneity of the material, uniform distribution of fibres and appropriate scatter of results. For each mentioned type of fibres a set of three test specimens was prepared with volume content 1% of fibres.
