The fibers are used to reinforce concrete prevent first of all the formation of microcracks and open cracks, increase the strength and resistance of concrete. They also used in the production of wall building materials such as autoclaved cellular concrete, ceramics or silicate. Literature shows positive effects of the use of basalt (aggregate and dust) as an addition to autoclaved sand-lime products and the chemical composition of basalt fibers is not significantly different from the chemical composition of the basalt itself. The addition of basalt fibers did not bring the expected results. The additive adversely affects the fragility of the product, compressive and tensile strength of the product as well as absorbability. This is related to the incorrect arrangement of fibers in the sand-lime matrix. It can not be unequivocally stated that the addition of basalt fibers has a negative effect on lime-sand products. Further attempts should be made to apply basalt fibers more efficiently and to consider how to properly distribute the elements in the matrix.
