摘　　要：为研究一种新型改性聚脲聚合物材料——聚异氰氨酸酯噁唑烷酮(简称POZD)加固足尺梁、板的受弯性能,设计了3根钢筋混凝土梁与3块钢筋混凝土板进行抗弯试验,其中1根未加固梁与1块未加固板分别作为对比件。试验结果表明:采用POZD材料加固有效提升了试验构件的抗弯承载力、抗弯刚度、抗裂性能和延性。In order to study the flexural property of a kind of new modified polyurea polymer material,i.e.polyisocyanurate oxazolidinone(POZD for short)for the reinforcement of full-scale beams and slabs,three reinforced concrete beams and three reinforced concrete slabs are designed for the bending resistance test.One unreinforced beam and one unreinforced slab are used as comparison specimens.The experimental results show that:the use of POZD material for reinforcement can effectively improve the flexural bearing capacity,flexural stiffness,crack resistance,and ductility of the test components.
