Main aim of this paper is to verify how the addition of basalt fibers to the autoclaved aerated concrete (AAC) may improve the performance of the composite material from a mechanical point of view. AAC is an environmentally friendly material known for its characteristics of lightness and versatility; basalt fibers are natural inorganic fibers, with good mechaanical properties. The insertion of fibers in a concrete leads to a change in the definition of mixture rheology; for this reason the research has primarily focused on the identification of the best mix design, operating on the dosage of the ingredients in order to find the best balance between executive requirements and final performance characteristics. For a better characterization of the final product, compression test on the fiber-reinforced specimens were carried out in order to determine mechanical properties. At the same time, a thermographic survey was made for a better understanding of the hygroscopic behavior of the material, downstream of a comparision with AAC specimens without fibers. The obtained result are illustrated in thi work demonstrating the feasibility and innovation of the process useful to guarantee the material e greater resistance to cracking, as well as satisfactory levels of comfort.
