Fiber stirring and dispersing process for mortar with high fiber mixing amount
The invention relates to the field of buildings, in particular to a fiber stirring and dispersing process for high-fiber-content mortar. Comprising the following steps: additionally adding fine foam before adding fibers, so that the volume of the mortar is increased, the fibers are not entangled and caked in the stirring process, and the uniformity of the mortar is ensured. And after the stirring is completed, adding a sufficient amount of defoaming agent to defoam the slurry. The invention solves the technical problems that under the condition of not reducing the length-diameter ratio of the fiber or reducing the mixing amount of the fiber, the fiber is not caked and is uniformly stirred when being added into a system, the construction performance of newly mixed concrete (mortar) slurry is ensured, and the toughening effect under the condition of high fiber mixing amount is finally ensured. In the technical process, stirring is little, the phenomenon of fiber caking and entanglement is not prone to occurring, and therefore it is guaranteed that the fibers can be evenly distributed in a mortar system in the high-mixing-amount state.
本发明涉及建筑领域，尤其涉及一种高纤维掺量砂浆用纤维搅拌分散工艺。包括在加入纤维前，额外加入微细泡沫，使砂浆体积增大，使纤维在搅拌过程不发生缠结结团，保证浆体均匀性。当搅拌完成后，再加入足量的消泡剂，对浆体进行消泡。本发明解决的技术问题是在不降低纤维长径比或降低纤维掺量的条件下，保证纤维加入体系内不结团、均匀搅拌，保证混凝土(砂浆)新拌浆体的施工性能，最终保证高纤维掺量下的增韧效果。本发明的工艺过程搅拌较少，纤维结团缠结现象不容易发生，从而保证了纤维在高掺量的状态下能均匀分布于砂浆体系中。
