裂缝问题在我国众多混凝土结构工程中普遍存在,是工程领域需要解决的主要问题。本文分析了混凝土裂缝产生的原因,并结合国内聚丙烯纤维的应用情况,拟提出在混凝土中加入聚丙烯纤维来抑制混凝土裂缝的产生与扩展,并详细分析了聚丙烯纤维在混凝土中的作用机理,结合具体工程提出,在混凝土中适量加入聚丙烯纤维是抑制混凝土开裂的一种方法。
The problem of cracks is common in many concrete structures in our country and is the main problem to be solved in engineering field. In this paper, the causes of concrete cracks are analyzed. Based on the application of polypropylene fibers in China, it is proposed to add polypropylene fibers to the concrete to suppress the generation and expansion of concrete cracks. The mechanism of polypropylene fibers in concrete is analyzed in detail , Combined with the specific project proposed in the amount of concrete added polypropylene fiber is a way to inhibit concrete cracking.
