摘要
近年来,3D打印混凝土因无模板、自动化与智能化等优势,在建筑业智能建造方向受到越来越多的关注,结合工程实践已形成诸多应用示范.工程应用需求也对3D打印混凝土性能提出了更高要求,常常需要选择配筋增强实现安全与可靠性设计.但3D打印混凝土配筋增强技术受制备工艺影响与传统混凝土工程有所差异,应针对打印条件下配筋增强方法进行科学优化与性能调控.因此,本文聚焦配筋工艺、材料与性能、细微观表征及数值分析等方面阐述了 3D打印混凝土配筋增强的基础研究进展;聚焦工程应用存在的问题,对配筋增强基础研究面临的挑战与未来发展也进行了简要讨论,力求为配筋3D打印混凝土结构安全应用提供参考.
Abstract
3D printed concrete(3DPC)has been the subject of ongoing study in recent years due to the growing trend of intelligent building materials industry and construction industry.Due to the automation,intelligent,and formwork-free advantages,several engineering demonstrations have been established.There are more demands on 3DPC properties because of its widespread application in engineering.Engineering applications are also placing greater demands on the performance of 3DPC which requiring selective reinforcement enhancements for safe and reliability design.3DPC reinforcement technology is different from casting concrete construction due to the changing preparation process.And scientific optimization and performance control should be carried out for the reinforcement method under printing.This paper focuses on the development of 3DPC reinforcement enhancement study in terms of the reinforcing process,materials and features,numerical analysis,and comprehensive microscopic characterization.In addition,the challenges faced by reinforcement enhancement fundamental research and the technical difficulties of future development are also briefly discussed.The intention is to serve as a reference for the scientific development of reinforced 3DPC structures,meeting the demand for safe applications guidance.
