基于工作性能的3D打印PVA纤维混凝土配合比优化设计

Optimization design of 3D printing PVA fiber concrete mix ratio based on work performance

3D打印具有快速成型、无需模具、可精细化制作等优点,越来越多地应用在建筑行业中。基于混凝土配合比针对3D打印施工特点进行改进,在材料流动性、凝结时间、抗压强度和抗折强度等方面进行一系列的优化设计,通过结构强度确定最佳配合比,在优化3D打印混凝土工作性能的基础上,提高混凝土的早期强度和总体力学性能。

Because of the advantages of rapid prototyping,no need for molds,and refinement,3D printing is increasingly used in the construction industry.Based on the concrete mix ratio,a series of optimized designs are carried out in terms of material fluidity,setting time,compressive strength and flexural strength for improving the 3D printing construction features.The optimum mix ratio is determined by the structural strength,and the early strength and overall mechanical properties of the concrete are improved on the basis of optimizing the working performance of the 3D printed concrete.
