摘要
聚丙烯纤维掺入混凝土中可明显改善其性能,混凝土掺入纤维后能有效控制混凝土早期干缩裂缝的数量、长度及宽度.聚丙烯纤维在混凝土中起阻裂和细化裂缝的作用。
The fraction of polypropylene fibre in concrete can greatly improve its performance,and can efficiently control the amount,length and width of early drying and shrinkage crack of the concrete.The polypropylene fibre plays a role to some extent in anti-crack and fine-drawn crack,according to the length and mixing amount of the fiber.
