摘要
3D打印技术具有快速成型、无需模具、可精细化制作复杂结构的特点,近年来被应用在建筑行业,来更快更好地完成工程建设。3D打印建筑材料多为水泥基材料,其工作性能和力学性能与普通混凝土有一定的区别。为得到适用于3D打印的混凝土材料,本研究基于3D打印材料的性能指标,利用PVA纤维改善混凝土性能,进一步调整配合比后,最终得出适用于3D打印的早强混凝土材料。
In recent years, 3D printing technology has been applied in the construction industry to build constructions faster and better due to its characteristics of rapid manufacturing, no need for molds and fine fabrication of complex structures. Most of the 3D printed building materials are cement-based materials, and their work performance and mechanical properties are different from ordinary concrete. Based on the performance indexes of 3D printing materials, this paper used PVA fiber to improve the performance of concrete in order to obtain concrete materials suitable for 3D printing. After further adjustment of the mix ratio, the final result is applicable to 3D printing of early strength concrete materials.
