A Study on Flexural Behaviour of Basalt Fiber Reinforced Geopolymer Concrete

In present study various proportions of basalt fibers are added to the geopolymer concrete and compressive and split tensile strength of the different mixes were compared with the geopolymer concrete without basalt fibers.

Fibers are added to the geopolymer concrete in the range of 0.5% to 2.5% at 0.5% increments. Flexural strength of different mixes were compared with reference mix (0% fiber).

From the results it is concluded that addition of basalt fibers at an optimum content to the geopolymer concrete can increase flexural strength.

Basalt is a volcanic rock and can be chopped into small particles then formed into continuous or chopped fibers. Basalt fiber has a higher working temperature and has a good resistance to impact load, fire resistance and chemical attack.

The applications of these basalt composites are plastic polymer reinforcement, soil strengthening, construction of bridges and highways, heat and sound insulation for residential and industrial buildings, bullet proof vests and retrofitting and rehabilitation of structures.
