Textile reinforced mortar (TRM) stands as an alternative for strengthening or repair reinforced concrete (RC) structures. It presents some advantages when compared to other consolidated techniques, however, as an innovative solution, more research and developments are needed. Therefore, this work is an exploratory study using a locally manufactured AR fiberglass textile (TEXIGLASS AR-360-RA-04) to flexural strengthening reinforced concrete beams. The beams geometry consisted of a rectangular section (1500 mm long, 200 mm deep and 120 mm wide) and were subjected to four point bending test. The experimental program investigates the influence of distinct textile layers (2, 3 and 4), age of TRM (3, 7 and 28 days) and the level of beam precracking (no precracking, 50% and 100% of the yielding load) on the flexural behavior of strengthened RC beams. It was mainly found that: (a) all beams presented an increment of ultimate load and the load at serviceability conditions (b) different TRM ages and precracking levels affect the cracking and yielding loads, but no significant influence on the ultimate load; (c) the load-carrying capacity enhances as the number of textile layers increases, as expected. Finally, the results indicate that the tested Brazilian textile has potential to be used in TRM.

纺织增强砂浆（TRM）可以替代加固或修复钢筋混凝土（RC）结构。与其他合并技术相比，它具有一些优势，但是，作为一种创新的解决方案，需要更多的研究和开发。因此，这项工作是一项探索性研究，使用本地制造的AR玻璃纤维织物（TEXIGLASS AR-360-RA-04）来抗弯加固钢筋混凝土梁。梁的几何形状由矩形截面（长1500 mm，深200 mm和宽120 mm）组成，并经过四点弯曲测试。该实验程序研究了不同的纺织品层（2、3和4），TRM的使用期限（3、7和28天）以及光束预裂水平（无预裂，屈服载荷的50％和100％）的影响。钢筋混凝土梁的抗弯性能。主要发现：（a）所有梁都表现出极限载荷的增加，并且在使用条件下载荷是（b）不同的TRM龄期和预裂化水平会影响裂纹和屈服载荷，但对极限载荷没有显着影响；（c）如预期的那样，随着纺织品层数的增加，承载能力增强。最后，结果表明，经过测试的巴西纺织品具有在TRM中使用的潜力。
