Abstract
It has been found that different type of fibers added in specific percentage to concrete improves the mechanical properties, durability and serviceability of the structure. Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Different types of Fibre reinforced concrete includes steel fibres, glass fibres, synthetic fibres and natural fibres Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine.
Highlights
The basalt is washed and melted. The manufacture of basalt fiber requires the melting of the quarried basalt rock at about 1400 °C (2550 °F)
Ma et al (2013) have studied the seismic behaviour of an earthquake-damaged reinforced concrete frame structure retrofitted with basalt fiber-reinforced polymer From the shake table tests of the fiber reinforced polymer (FRP)-retrofitted structure the authors have concluded that the shear capacity, ductility, and hysteretic energy dissipation capacity of each story were greatly improved and that the beamcolumn joint failure mode was prevented and the structure experienced much less damage compared with the original structure when subjected to ground motions of the same intensity
Wu et al (2013) have studied the flexural behaviour of RC beams strengthened with steelwire continuous basalt fiber composites plates (SBFCP).The authors have observed that SBFCP strengthened beams have competitive advantages, with respect to their durability and performance-cost ratio, in comparison with specimen strengthened with carbon fiber reinforced polymer (CFRP) materials
Summary
The basalt is washed and melted. The manufacture of basalt fiber requires the melting of the quarried basalt rock at about 1400 °C (2550 °F). The authors have bonded the basalt fiber sheets on the surface of beam and this flexure strengthened specimens have tested under bending load.
