预应力高强锚固灌浆材料研究与应用

The Research and Application of the Prestressed High-strength Anchor Grouting

介绍了一种新型预应力高强锚固灌浆材料-聚丙烯纤维水泥砂浆,研究表明:聚丙烯纤维水泥砂浆比传统水泥砂浆更具优越性,粘结力高,体积稳定性好,耐久性优良,并在实际工程中得到了验证。

In this article it introduces a new type prestressed high--strength anchor grouting --polypropylene fiber Cement mortar , the research findings indicates that polypropylene fiber Cement mortar is better than conventional Cement mortar in binding power and capacity stability and durability , its effectiveness is proved in the practicable project.
