In this work, we studied ettringite formation, C-S-H propagation, and the thermomechanical properties of sugarcane bagasse (SBC) fiber-reinforced concrete with a maximum dosage of 0.17% by weight. Scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and infrared (IR) analyses were performed. TGA results showed bio-based concrete resistant to temperatures exceeding 500°C. TGA results revealed thermal stability of bio-based concrete. SEM analysis showed ettringite and C-S-H propagation without altering mechanical properties. These results are consistent with those obtained by other authors.
