Method for adjusting arrangement order of chopped fibers in high-ductility concrete
The invention provides a method for adjusting arrangement orderliness of chopped fibers in high-ductility concrete, and relates to the technical field of building material preparation. The method for adjusting the arrangement order of the chopped fibers in the high-ductility concrete specifically comprises the following steps: S1, preparing materials; s2, preparing a viscosity reducer; s3, preparing a thixotropic agent; s4, stirring treatment; and S5, shunting treatment. According to the method, the problem that distribution of chopped fibers in high-ductility concrete is difficult to control is solved through multiple innovative technologies, the viscosity and frictional resistance of concrete slurry are remarkably reduced by using the thixotropic agent and the viscosity reducer under ultrahigh-speed stirring, it is ensured that the fibers are uniformly dispersed and are not prone to caking, and through a discontinuous arc-shaped splitter plate, the distribution of the chopped fibers in the high-ductility concrete is controlled. According to the method, the fibers are arranged in order in the conveying process, distribution of aquatic plants in natural fluid is simulated, the utilization rate of the fibers and the ductility of the concrete are improved, the cost of materials and equipment is reduced, and the overall performance and economic benefits of the high-ductility concrete are remarkably improved.
本发明提供一种高延性混凝土中短切纤维排列有序性调整方法，涉及建筑材料制备技术领域。该高延性混凝土中短切纤维排列有序性调整方法，具体包括以下步骤：S1.材料准备；S2.降粘剂准备；S3.触变剂准备；S4.搅拌处理；S5.分流处理。本发明的方法通过多种创新技术，解决了高延性混凝土中短切纤维分布难以控制的问题，使用触变剂和降粘剂，在超高速搅拌下，显著降低混凝土浆体的粘度和摩擦阻力，确保纤维均匀分散，不易结团，通过间断式弧型分流板，使纤维在输送过程中得到有序排列，模仿自然流体中水草的分布，该方法不仅提高了纤维的利用率和混凝土的延性，还降低了材料和设备的成本，显著提升了高延性混凝土的整体性能和经济效益。
