From the experiments , we can see the affect of concrete performances mixing with liter polypropylene fiber and glass fiber is minor . compare with common concrete , the crack - load of concrete slab mixing with liter polypropylene fiber and glass fiber is marked improved . mixing with liter polypropylene fiber and glass fiber , the behavior of cracks - resisting of is marked improved , and the cracks are controlled and smeller 研究表明,在混凝土中掺入低掺量的聚丙烯纤维或玻璃纤维对抗压强度及抗拉强度的影响较小;纤维混凝土板比普通混凝土板的开裂荷载有较为显著的提高;加入低掺量的聚丙烯纤维后,混凝土板的抗塑性开裂性能有显著提高,可以抑制、细化裂缝。
