Basalt fiber alkali resistance and methods to increase it

In this paper, destruction mechanism for basalt fiber in cement concrete is described and a variety of methods to protect it from alkali-corrosion are analyzed.

The main activity of Global Basalt Engineering LLC is creation of effective productions on release of continuous basalt fiber (СBF) with technologies of the last generation and composites on the basis of СBF (Basalt Fiber-Reinforced Polymer Composites as BFRP).

The use of basalt fiber for disperse concrete reinforcement is a very promising direction in the concrete technology. However, the constraint for mass introduction of this material is a low resistance of basalt fibers to the products of cement hydration.
