Abstract

The aim of this project was to evaluate the performance of M25 grade basalt fibre concrete with the normal M25 grade concrete. Concrete has a good serviceability, but it is failing in some conditions due to the improper mixing which results in cracking. So the concrete is likely to be get replaced by other material like fibres, to get good serviceability. In the same way the additive material should be economic. Basalt is a naturally available material which will increase the strength of concrete by producing infinite variance in strength compared to normal concrete. The main aim of this investigation is first to obtain the strength of normal concrete of grade M25 with locally available ingredients and then to study the effect of different proportions of basalt fibre in the mix and to find out the effect on various mix proportions of basalt fibres in the mix range to the concrete. And the concrete specimens were tested at different age levels such as 7, 14, 28 for mechanical properties of concrete namely, cube compressive strength. Based on the laboratory experiments cube specimens have been designed for basalt fibre concrete tests. The basalt fibres in the concrete mixture have been carried in the range 0 to 6%. The basalt fibre containing concrete mixtures have been aged at 7, 14, 28 days. When basalt fibres are mixed in the concrete at different percentage values, different densities such as 6kg/m3, 12kg/m3, 18kg/m3, 24kg/m3, 30kg/m3, 36kg/m3 have been obtained.
