摘 要:通过刀口模诱导开裂试验,研究了复合活性剂+聚酯纤维对混凝土抗裂收缩性能的影响,同时采用宏观性能试验和细观结构图像分析了抗裂机理。研究表明,复合活性剂+聚酯纤维掺入后,试样裂缝开裂面积减少率效果显著。
Abstract: The early cracking shrinkage resistance of concrete with composite active agent and polyester fiber was investigated by knife mold induced cracking plate test. The crack resistance mechanism was analyzed by using mechanical tests and microstructure image analysis. The results show that the crack cracking area of sample is significantly reduced after incorporating composite active agent and polyester fiber.
