摘要
在混凝土的拌和料中掺进一定数量的聚丙烯短纤维，可以有效地防止混凝土早期出现的龟裂，还可明显地降低混凝土的渗透性。
After adding a certain amount of polypropylene shore fibre to the mixing material of concrete, cracks on concrete at early stage are prevented effectively and the permeability of concrete is reduced obviously, thus the durability of maritime reinforced concrete is improved greatly.
