Basalt fiber inherits all these qualities and has a low cost compared to carbon fibers, alkali resistant AR glass and polypropylene. Basalt fiber is produced from basalt crushed stone melt at a temperature of 1500 °C. The structure of Technobasalt® fiber has a uniform quality due to its natural origin and a smoothly running production cycle.

 · The test results show that the presence of polypropylene (PP) fiber and basalt fiber (BF) in the mortar reduces the initial slump flow and increases the slump flow loss rate. The bond strength and flexural strength of fiber-reinforced mortar (FRM) are improved, whereas no obvious improvement on the compressive strength has been observed.
