Abstract

This study investigates the enhancement of concrete slabs using a biopolymer-modified cementitious repair material (CXT) composed of Ordinary Portland Cement, Xanthan Gum, and Tartaric Acid Powder. The innovative formulation of CXT aims to improve the mechanical properties of repaired concrete structures. Experimental results demonstrate that CXT significantly enhances mechanical properties such as the load-bearing capacity of concrete slabs. Non-destructive testing methods, including the Rebound Hammer test and Ultrasonic Pulse Velocity (UPV), as well as destructive testing methods, were employed to evaluate the performance of CXT in repairing cracks. The study highlights the improved load-bearing capacity and structural integrity of CXT-repaired slabs, contributing to increased longevity and reduced maintenance costs of concrete structures. Furthermore, the sustainability metrics of CXT, including Process Mass Intensity (PMI), Energy Intensity (EI), Environmental Factor (E-Factor), and Reaction Mass Efficiency (RME), are evaluated, illustrating its cost-effectiveness and environmental benefits. This comprehensive approach underscores the potential of CXT as a durable and sustainable repair material for concrete infrastructure.

黄原胶基复合材料修复钢筋混凝土结构裂缝的效果

本研究调查了使用由普通硅酸盐水泥、黄原胶和酒石酸粉末组成的生物聚合物改性水泥基修复材料（CXT）对混凝土板进行增强的情况。CXT 的创新配方旨在改善修复后混凝土结构的机械性能。实验结果表明，CXT 能显著提高混凝土板的承载能力等力学性能。研究采用了非破坏性测试方法，包括回弹锤测试和超声波脉冲速度（UPV），以及破坏性测试方法，来评估 CXT 在修复裂缝方面的性能。研究结果表明，CXT 修复板的承载能力和结构完整性得到了改善，有助于延长混凝土结构的使用寿命并降低维护成本。此外，研究还评估了 CXT 的可持续性指标，包括工艺质量强度 (PMI)、能源强度 (EI)、环境因子 (E-Factor) 和反应质量效率 (RME)，以说明其成本效益和环境效益。这种综合方法凸显了 CXT 作为混凝土基础设施耐用和可持续修复材料的潜力。
