聚丙烯纤维混凝土在耐磨地面中的应用

在混凝土中掺加聚丙烯纤维,可以有效抑制混凝土的早期开裂,降低混凝土产生收缩裂缝的可能性.通过试验发现,掺加聚丙烯纤维的混凝土与不掺加聚丙烯纤维的混凝土相比,能提高抗折强度,但抗压强度没有明显改善;随着聚丙烯纤维用量的提高.混凝土坍落度逐渐减小;掺加聚丙烯纤维的混凝土耐久性有很好的提高.通过试验确定了掺加聚丙烯纤维的施工配合比,并在新中国国际展览中心取得较好的应用效果.

Polypropylene fiber reinforced concrete for wear-resistant surface

Mixing polypropylene fiber in concrete can effectively inhibit the early concrete cracking and reduce the possibility of concrete cracking.Polypropylene fiber concrete and non-mixing polypropylene fiber concrete were compared to no difference in compreesive strength,but the flexual strength and durability are improved.As the increasing in the amount of polypropylene fiber,concrete slump decreases gradually.The construction mix proportion of polypropylene fiber is determined through the experiment,and it ach...
