Photographs of cross-section of automated reinforcement integration in Shotcrete 3D Printing through green state milling

This data was generated in association with the paper: Dörrie, R., Kloft, H., Sawicki, B., Freund, N., & Lowke, D. (2024, September 4). Automated reinforcement integration in Shotcrete 3D Printing through green state milling. 4th RILEM International Conference on Concrete and Digital Fabrication DC 2024, ISBN 978-3-031-70030-9, RILEM 2024. The concept presented in paper assumes reinforcement integration is Shotcrete 3D Printed elements by 1) spraying the core of the element; 2) milling of grooves before concrete hardens and installation of reinforcement bars; 3) spraying the concrete cover. It investigates influence of milling (time and notch geometry) and spraying (time) parameters on quality of obtained element in terms of voids, spraying shadows, etc. After fabrication of elements with given fabrication parameters and hardening of concrete (minimum 7 days), they were sliced to reveal the cross-section. The slices where photographed. These photographs are presented in the current dataset. See readme file and paper for more details.

本数据集关联的研究论文为：Dörrie, R.、Kloft, H.、Sawicki, B.、Freund, N. 与 Lowke, D. 于2024年9月4日发表的《通过绿色状态铣削（green state milling）实现喷射混凝土3D打印（Shotcrete 3D Printing）中的配筋自动化集成》，收录于第4届国际材料与结构研究实验联合会（RILEM）国际混凝土与数字化建造大会（DC 2024），国际标准书号（ISBN）为978-3-031-70030-9，属于RILEM 2024会议论文集。该论文提出的配筋集成方案，针对喷射混凝土3D打印构件采用以下三步流程：1）喷射构件芯部混凝土；2）在混凝土硬化前铣削凹槽并安装钢筋；3）喷射混凝土保护层。本研究探究了铣削参数（铣削时间与槽口几何形状）及喷射参数（喷射时间）对构件质量的影响，评估维度包括孔隙、喷射阴影等缺陷。研究人员按照预设制备参数制作构件，并在混凝土养护至少7天后，对构件进行切片以暴露其横截面，随后对切片进行拍摄。本数据集即包含这些拍摄得到的照片。更多细节可参阅数据集自述文件与原论文。
