Abstract

This study explores the viability of mango seed hydrochar (MSH), synthesized through hydrothermal carbonization (HTC), as a sustainable supplementary cementitious material. Incorporating MSH at an optimal 1.5 % replacement level significantly enhanced mortar performance, achieving compressive and flexural strengths of 41.7 MPa and 7.2 MPa, respectively surpassing the control mix. Advanced characterization techniques including powder X-ray diffraction (PXRD), Fourier-transform infrared spectroscopy (FTIR), BET, and Micro-CT confirmed improved pozzolanic activity, increased mesoporosity, and refined matrix densification. The results demonstrate MSH potential to enhance microstructural integrity and support eco-efficient, non-structural cementitious applications.

芒果籽衍生的碳氢化合物作为胶凝材料中的可持续添加剂：微观结构和性能分析

本研究探讨了通过水热炭化（HTC）合成芒果籽氢炭（MSH）作为可持续补充胶凝材料的可行性。加入最优1.5%替代水平的MSH显著提高了砂浆性能，抗压和抗折强度分别达到41.7 MPa和7.2 MPa，超过了对照混合料。先进的表征技术，包括粉末x射线衍射（PXRD）、傅里叶变换红外光谱（FTIR）、BET和Micro-CT，证实了火山灰活性的改善，介孔率的增加，以及基体致密化的改善。结果表明，MSH具有增强微观结构完整性和支持生态高效、非结构性胶凝应用的潜力。
