Basalt fibres in concrete can improve the structural behaviour like strength, stiffness and permeability [6], [11], [15]. Basalt fibre in concrete effectively curb the drying shrinkage of concrete [5]. By using modern technology for industrial production, basalt fibres can be produced for the same price as or even less than glass fibre.

The natural aggregates are one of the main components in the production of concrete. Although deposits of natural aggregates lie on the earth's surface or at low depths and belong to common deposits, the shortage of aggregate, especially natural sand, is presently observed in many countries. In such a situation, one is looking for other …
