摘要

本研究调查了大戟科仙人掌(ETC)灌注混凝土的增强效果,重点关注其微观结构特征和机械性能。ETC 混凝土以卓越的拉伸延展性和耐久性著称,研究采用先进的三维 X 射线断层扫描和能量色散 X 射线光谱(EDX)分析对其进行了表征。含有 9% ETC 提取物混合物的试样经过了高分辨率显微计算机断层扫描,显示出平均 3.3% 的孔隙率,并提供了对孔隙、纤维和集料等内部特征的详细了解。通过乙二胺四乙酸(EDX)图谱确定了关键元素,包括硅、氧、镁和钙,突出显示了碳酸钙和青金石的形成。这项研究填补了人们对 ETC 混凝土微观结构和力学行为了解的空白,利用无损成像和化学分析提供了全面的见解。研究结果表明,可以对 ETC 混凝土进行优化,以提高其在可持续建筑中的性能,并突出其在要求高耐久性和延展性的应用中的潜力。这项研究的新颖之处在于它应用了先进的成像和分析技术来优化 ETC 混凝土的混合设计、评估耐久性并制定缓解结构问题的策略,从而为了解材料的特性和行为提供了宝贵的资料。

Characterization of Euphorbia Tortilis Cactus Concrete Specimen by 3D X-ray Tomography

This study investigates the enhancement of Euphorbia Tortilis Cactus (ETC) infused concrete, focusing on its microstructural characteristics and mechanical properties. ETC concrete, known for superior tensile ductility and durability, was characterized using advanced 3D X-ray tomography and energy dispersive X-ray spectroscopy (EDX) analysis. Specimens with a 9% ETC extract mix underwent high-resolution Micro Computed Tomography scanning, revealing an average porosity of 3.3% and providing detailed insights into internal features like pores, fibers, and aggregates. EDX mapping identified key elements, including Si, O, Mg, and Ca, highlighting calcium carbonate and brucite formations. This research addresses gaps in understanding ETC concrete’s microstructure and mechanical behavior, using non-destructive imaging and chemical analysis to offer comprehensive insights. The findings suggest that ETC concrete can be optimized for enhanced performance in sustainable construction, highlighting its potential for applications requiring high durability and ductility. The study’s novelty lies in its application of advanced imaging and analysis techniques to optimize ETC concrete mix designs, assess durability, and develop strategies for mitigating structural issues, thus providing valuable insights into the material’s properties and behavior.

期刊介绍: Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
