Alfa fiber reinforced concretes are not used to their full potential due to the limited information on their properties, especially in more severe environments. In this study, the effects of elevated temperature on the properties of concretes reinforced with Alfa fiber were analyzed. The influence of fiber length on reinforced concretes is mainly investigated. ; For this purpose, five types of structural concretes were formulated; two types of concrete reinforced with 1% Alfa fiber volume using two different fiber lengths of 20 mm and 30 mm (AC-20, and AC-30), and three control concretes, two polypropylene fiber reinforced concretes (PC) using the same fiber length (PC-20, PC-30), and one ordinary concrete (OC). ; The results showed that with the increase of temperature, the mechanical performance decreased and the porosity rose continually for all mixtures. However, the use of Alfa fiber with a length of 20 mm showed the optimal results in terms of compressive and tensile strength, even at temperatures of 600 degress C. This finding suggests that Alfa vegetable fiber can be used to produce more sustainable concretes with acceptable mechanical properties compared to the use of polypropylene fiber, even under severe conditions of elevated temperature
