在这项工作中，展示并讨论了对 PET 和 CFRP 加固的混凝土梁样本进行的一系列初步测试的结果。测试的新颖之处在于使用了废料，并取得了有希望的结果。增强材料由 PET 和 CFRP 制成，分别排列为连续棒材和条带。它们位于样本内部，与钢筋混凝土元件中的钢筋处于相同位置。对于这两种情况，人们注意到它们限制了裂缝的存在，特别是避免和/或减少了钢筋混凝土结构元件中的腐蚀过程。特别是，分析了这些纤维增强混凝土的混凝土纤维粘附力和整体行为，以评估未来研究的可能性。然而，测试结果表明，用 CFRP 条加固的样本具有更好的性能。 (c) 2016 Elsevier Ltd. 保留所有权利。
In this work the results of a series of preliminary tests on concrete beam specimens reinforced with PET and CFRP are shown and discussed. The novelty in the tests lies in the use of a waste material with promising results. The reinforcement is made with PET and CFRP are arranged as continuous bars and strips, respectively. They are positioned inside the specimen, in the same position of the steel bars in a reinforced concrete element. For both cases it is noticed that they limit the presence of cracks and, especially, avoid and/or reduce the corrosion processes in reinforced concrete structural elements. In particular, the concrete-fibers adhesion and the global behavior of these fiber reinforced concretes is analyzed in order to evaluate the possibility of future investigation. However, the results of the tests showed a better behavior for specimens reinforced with CFRP strips. (c) 2016 Elsevier Ltd. All rights reserved.
