聚丙烯纤维混凝土或砂浆的施工及力学性能

Construction and Mechanical Capabiity of Polypropylene Fiber Concrete or Mortar

进行了聚丙烯纤维掺入量对混凝土及砂浆的操作性能及力学性能影响的试验研究。试验表明 ,混凝土及砂浆中聚丙烯纤维掺入量的变化 ,将对混凝土及砂浆的用水量、砂率、劈裂抗拉强度以及变形性能等方面产生影响。在保证混凝土及砂浆的施工操作性能前提下 ,找出最佳掺入量及配合比。

Effects of mixing amount of polypropylene fiber on properties of concrete or mortar were studied experimently.The experiment indicated that the changes of mixing amount of polypropylene fiber will influence such aspects as water consumption,sand coarse aggregate ratio,split tensile strength and deformation,etc.of concrete or mortar.Furtheremore,under construction serviceability premise of concrete or mortar,the optimal mixing amount of polypropylene fiber and it's cooperational ratio with concrete or mortar were abtained.
