Paragraph starter

This research demonstrates that textile-reinforced alkali-activated mortar (TRAAM), derived from industrial waste, can significantly enhance the shear capacity of masonry structures by up to 335%. Furthermore, TRAAM exhibits remarkable thermal resilience, maintaining its performance after exposure to high temperatures (up to 550 °C) with minimal degradation. This suggests TRAAM is a promising sustainable material for retrofitting applications, offering improved structural integrity and fire resistance.
