Fiber orientation method and fiber concrete prepared based on fiber orientation method
The invention belongs to the field of fiber concrete, and provides a fiber orientation method and fiber concrete prepared based on the fiber orientation method.The fiber orientation method comprises the steps that end balls with the density larger than 2500kg/m < 3 > are manufactured; the end balls are connected with fibers with the length ranging from 10 mm to 30 mm, and the fibers with the end balls at one ends are obtained; wherein the mass of the fibers is smaller than that of the end balls; and adding the fiber with the end ball at one end into cement paste, uniformly mixing, longitudinally vibrating the paste, enabling the end ball to drag the fiber to sink, and orienting the fiber, thereby obtaining the cement paste. Under the requirement of the same bearing capacity, the fiber mixing amount can be reduced by adopting the method, so that the adverse effect caused by overhigh fiber yield is reduced. Under the same fiber mixing amount, the bearing capacity of the concrete can be remarkably improved, and the method is simple and high in practicability.
本发明属于纤维混凝土领域，提供了一种纤维定向的方法及基于此制备的纤维混凝土，包括：制作密度大于2500kg/m3的端部球；将所述端部球与长度为10～30mm的纤维相连，得到一端带有端部球的纤维；其中，纤维质量小于端部球的质量；将所述一端带有端部球的纤维加入到水泥浆体中，混匀，并对浆体进行纵向振动，端部球拖拽纤维下沉，定向纤维，即得。同等承载力需求下，采用本发明可降低纤维掺量，从而降低因纤维产量过高带来的不利影响。同等纤维掺量下，本发明可显著提高混凝土承载力，方法简单，实用性强。
