Use of Basalt Fibers for Soil Improvement
Acta Physica Polonica A, 2016 Soil reinforcement with natural and man-made fibers is one of the techniques to improve a number of mechanical and physical properties of soils. Although basalt originated fibers are currently being used for concrete, it is not an easy task to find a source in literature concerning the use of basalt fibers for soil improvement.

Effect of macro polypropylene fiber and basalt fiber on impact resistance of basalt fiber‐reinforced polymer‐reinforced concrete [PDF]
Structural Concrete, 2020 AbstractIn this paper, the effect of macro nonmetallic fibers (i.e., polypropylene fibers and basalt fibers) on the impact response of basalt fiber‐reinforced polymer‐reinforced concrete (FRP‐RC) discs is experimentally investigated using a self‐developed drop‐weight impact test device.
