Original Abstract
Use of high strength concrete (HSC) becoming inevitable in case of modern structures, which require application of advanced materials. High strength of concrete can be reached by higher dose of cement or addition of various kinds of fibres as a dispersed reinforcement. In practice are most commonly used steel, glass and polypropylene fibres, but basalt fibres are still under investigation. Basalt is highly resistance to aggressive chemicals and stable in high temperatures in comparison to other materials used for dispersed reinforcement. This study focuses on use of chopped basalt fibres in purpose to enhance properties of harden concrete. Six mixes with various dose of cement and chopped basalt fibres were designed for evaluation of properties of fresh and hardened concrete. As it was expected, chopped basalt fibres have negative influence on workability of fresh concrete but in comparison to other types of fibres the decrease is not that dramatic. Test results indicate increase of compressive strength after 28 days and even higher gain of strength after 90 days in case of mixes with addition of chopped basalt fibres. Reduction of strength due to exposure to high temperatures is lower in case of mixes with application of chopped basalt fibres.
