Abstract
Extrusion based 3D Concrete Printing (E-3DCP) is a rapidly growing method of construction due to its ability to manufacture bespoke architectural and structural elements without incurring the additional time and costs typically associated with the manufacturing of the formwork of these components. However, Complex geometries such as overhangs, bridges, and cantilevers pose significant challenges to E-3DCP, increasing the risk of premature failure during 3D printing and complicating the integration of longitudinal reinforcement. In response to these challenges, researchers have developed various techniques and strategies to mitigate these complexities and failures. This paper provides a comprehensive review of these methods, evaluating their advantages and disadvantages, and identifying research gaps in the current literature.
基于挤压的三维混凝土打印(E-3DCP)是一种快速发展的建筑方法,因为它能够制造定制的建筑和结构元素,而无需承担通常与这些组件的模板制造相关的额外时间和成本。然而,悬臂、桥梁和悬臂等复杂几何形状给 E-3DCP 带来了巨大挑战,增加了 3D 打印过程中过早失效的风险,并使纵向加固的集成变得更加复杂。为了应对这些挑战,研究人员开发了各种技术和策略来减轻这些复杂性和故障。本文全面回顾了这些方法,评估了它们的优缺点,并指出了当前文献中存在的研究空白。
期刊介绍:
Automation in Construction is an international journal that focuses on publishing original research papers related to the use of Information Technologies in various aspects of the construction industry. The journal covers topics such as design, engineering, construction technologies, and the maintenance and management of constructed facilities.
The scope of Automation in Construction is extensive and covers all stages of the construction life cycle. This includes initial planning and design, construction of the facility, operation and maintenance, as well as the eventual dismantling and recycling of buildings and engineering structures.
