Technical Field

[0002] Fiber concrete is a composite material composed of fibers as reinforcing materials. Fibers can control the development of cracks in the matrix concrete, thereby improving the crack resistance and toughness of concrete. Hydroxymethyl cellulose is an effective surfactant that promotes the dispersion of fibers in concrete slurry. It can also be called a dispersant. It can form a thicker steric layer on the fiber surface. Its surface is prone to generate charges and form repulsive forces to make the fibers evenly distributed in the slurry, thereby realizing the high-value utilization of fibers in concrete. Generally, a fiber stirring device is used to stir the fibers and hydroxymethyl cellulose to achieve fiber dispersion.

[0003] At present, during the mixing process of fiber concrete, it is necessary to add dispersants to disperse the fiber concrete. However, most of the current treatment methods are to directly discharge the dispersed solution and then add new dispersants to treat the fiber concrete. This will affect the working efficiency of the fiber concrete due to the range of adding dispersants. Utility Model Content
