Abstract

This study investigates the effects of adding nano-TiO₂ (1–5%) to flash-based cement mortar on structural performance, chemical composition, and mechanical strength. Nano-TiO₂ (nano-titanium dioxide) is added in different amounts of 1% to 5% by weight of cement, while flash, a refined form of fly ash, is utilized as a 20% substitute for cement. Compressive strength tests, FTIR (Fourier Transform Infrared) spectroscopy, flexural strength tests, compression testing machine analysis, and X-ray diffraction (XRD) analysis are used in the study to assess the material’s compressive strength, flexural strength, and structural composition. The findings show that while larger dosages cause particle agglomeration, which lowers efficiency, nano-TiO₂ at 2% dosage offers the greatest strength enhancement. The influence of nano-TiO₂ on the structure of cement mortar is validated by FTIR and XRD investigations, which confirm the changes in material composition. According to the study’s findings, adding nano-TiO₂ to flash-based cement mortar greatly increases its strength and durability, making it a good choice for high-performance and environmentally friendly building applications.

纳米tio2颗粒混凝土的压缩和红外光谱表征

本研究考察了在闪蒸水泥砂浆中加入纳米tio2（1-5%）对水泥结构性能、化学成分和机械强度的影响。将纳米二氧化钛（纳米二氧化钛）按水泥重量的1% ~ 5%添加到水泥中，而将粉煤灰的精炼形式闪光作为20%的水泥替代品。抗压强度测试、FTIR（傅里叶变换红外）光谱、弯曲强度测试、压缩试验机分析和x射线衍射（XRD）分析在研究中用于评估材料的抗压强度、弯曲强度和结构成分。研究结果表明，较大的添加量会导致颗粒团聚，降低效率，而纳米tio2在2%的添加量下具有最大的强度增强效果。通过FTIR和XRD研究证实了纳米tio2对水泥砂浆结构的影响，证实了材料成分的变化。根据研究结果，在闪蒸水泥砂浆中添加纳米tio2可大大提高其强度和耐久性，使其成为高性能和环保建筑应用的良好选择。
